Refactor codebase for consistency and readability

- Standardize array and vector formatting for clarity.
- Adjust spacing and indentation in examples and TUI code.
- Ensure proper newline usage across files (e.g., LICENSE, TOML files, etc.).
- Simplify `.to_string()` and `.ok()` calls for brevity.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that are welcoming, open, and respectful.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+*   Demonstrating empathy and kindness toward other people
+*   Being respectful of differing opinions, viewpoints, and experiences
+*   Giving and gracefully accepting constructive feedback
+*   Accepting responsibility and apologizing to those affected by our mistakes,
+    and learning from the experience
+*   Focusing on what is best not just for us as individuals, but for the
+    overall community
+
+Examples of unacceptable behavior include:
+
+*   The use of sexualized language or imagery, and sexual attention or
+    advances of any kind
+*   Trolling, insulting or derogatory comments, and personal or political attacks
+*   Public or private harassment
+*   Publishing others' private information, such as a physical or email
+    address, without their explicit permission
+*   Other conduct which could reasonably be considered inappropriate in a
+    professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+[security@owlibou.com](mailto:security@owlibou.com). All complaints will be
+reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interaction in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+
+## Attribution

+# Contributing to Owlen
+
+First off, thank you for considering contributing to Owlen! It's people like you that make Owlen such a great tool.
+
+Following these guidelines helps to communicate that you respect the time of the developers managing and developing this open source project. In return, they should reciprocate that respect in addressing your issue, assessing changes, and helping you finalize your pull requests.
+
+## Code of Conduct
+
+This project and everyone participating in it is governed by the [Owlen Code of Conduct](CODE_OF_CONDUCT.md). By participating, you are expected to uphold this code. Please report unacceptable behavior.
+
+## How Can I Contribute?
+
+### Reporting Bugs
+
+This is one of the most helpful ways you can contribute. Before creating a bug report, please check a few things:
+
+1.  **Check the [troubleshooting guide](docs/troubleshooting.md).** Your issue might be a common one with a known solution.
+2.  **Search the existing issues.** It's possible someone has already reported the same bug. If so, add a comment to the existing issue instead of creating a new one.
+
+When you are creating a bug report, please include as many details as possible. Fill out the required template, the information it asks for helps us resolve issues faster.
+
+### Suggesting Enhancements
+
+If you have an idea for a new feature or an improvement to an existing one, we'd love to hear about it. Please provide as much context as you can about what you're trying to achieve.
+
+### Your First Code Contribution
+
+Unsure where to begin contributing to Owlen? You can start by looking through `good first issue` and `help wanted` issues.
+
+### Pull Requests
+
+The process for submitting a pull request is as follows:
+
+1.  **Fork the repository** and create your branch from `main`.
+2.  **Set up pre-commit hooks** (see [Development Setup](#development-setup) above). This will automatically format and lint your code.
+3.  **Make your changes.**
+4.  **Run the tests.**
+    - `cargo test --all`
+5.  **Commit your changes.** The pre-commit hooks will automatically run `cargo fmt`, `cargo check`, and `cargo clippy`. If you need to bypass the hooks (not recommended), use `git commit --no-verify`.
+6.  **Add a clear, concise commit message.** We follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) specification.
+7.  **Push to your fork** and submit a pull request to Owlen's `main` branch.
+8.  **Include a clear description** of the problem and solution. Include the relevant issue number if applicable.
+
+## Development Setup
+
+To get started with the codebase, you'll need to have Rust installed. Then, you can clone the repository and build the project:
+
+```sh
+git clone https://github.com/Owlibou/owlen.git
+cd owlen
+cargo build
+```
+
+### Pre-commit Hooks
+
+We use [pre-commit](https://pre-commit.com/) to automatically run formatting and linting checks before each commit. This helps maintain code quality and consistency.
+
+**Install pre-commit:**
+
+```sh
+# Arch Linux
+sudo pacman -S pre-commit
+
+# Other Linux/macOS
+pip install pre-commit
+
+# Verify installation
+pre-commit --version
+```
+
+**Setup the hooks:**
+
+```sh
+cd owlen
+pre-commit install
+```
+
+Once installed, the hooks will automatically run on every commit. You can also run them manually:
+
+```sh
+# Run on all files
+pre-commit run --all-files
+
+# Run on staged files only
+pre-commit run
+```
+
+The pre-commit hooks will check:
+- Code formatting (`cargo fmt`)
+- Compilation (`cargo check`)
+- Linting (`cargo clippy --all-features`)
+- General file hygiene (trailing whitespace, EOF newlines, etc.)
+
+## Coding Style
+
+-   We use `cargo fmt` for automated code formatting. Please run it before committing your changes.
+-   We use `cargo clippy` for linting. Your code should be free of any clippy warnings.
+
+## Commit Message Conventions
+
+We use [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) for our commit messages. This allows for automated changelog generation and makes the project history easier to read.
+
+The basic format is:
+
+```
+<type>[optional scope]: <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+**Types:** `feat`, `fix`, `docs`, `style`, `refactor`, `test`, `chore`, `build`, `ci`.
+
+**Example:**
+
+```
+feat(provider): add support for Gemini Pro
+```
+
+Thank you for your contribution!

 ```
 
 ## Using the TUI
 
-### Mode System (Vim-inspired)
+OWLEN uses a modal, vim-inspired interface. Press `?` in Normal mode to view the help screen with all keybindings.
 
-**Normal Mode** (default):
+- **Normal Mode**: Navigate with `h/j/k/l`, `w/b`, `gg/G`.
-- `i` / `Enter` - Enter editing mode
+- **Editing Mode**: Enter with `i` or `a`. Send messages with `Enter`.
-- `a` - Append (move right and enter editing mode)
+- **Command Mode**: Enter with `:`. Access commands like `:quit`, `:save`, `:theme`.
-- `A` - Append at end of line
-- `I` - Insert at start of line
-- `o` - Insert new line below
-- `O` - Insert new line above
-- `v` - Enter visual mode (text selection)

-- `Ctrl-d/u` - Half-page scroll
-- `Ctrl-f/b` - Full-page scroll
-- `Tab` - Cycle focus between panels
-- `p` - Paste from clipboard
-- `dd` - Clear input buffer
-- `q` - Quit
 
-**Editing Mode**:
+## Documentation
-- `Esc` - Return to normal mode
-- `Enter` - Send message and return to normal mode
-- `Ctrl-J` / `Shift-Enter` - Insert newline
-- `Ctrl-↑/↓` - Navigate input history
-- Paste events handled automatically
 
-**Visual Mode**:
+For more detailed information, please refer to the following documents:
-- `j/k/h/l` - Extend selection
-- `w/b/e` - Word-based selection
-- `y` - Yank (copy) selection
-- `d` - Cut selection (Input panel only)

-# Debug build
-cargo build
-
-# Release build
-cargo build --release
-
-# Build with all features
-cargo build --all-features

-```
-
-### Development Notes
-- Standard Rust workflows apply (`cargo fmt`, `cargo clippy`, `cargo test`)
-- Codebase uses async Rust (`tokio`) for event handling and streaming
-- Configuration is cached in `~/.config/owlen` (wipe to reset)
-- UI components are extensively tested in `owlen-core/src/ui.rs`

+
+This crate provides an implementation of the `owlen-core::Provider` trait for the [Ollama](https://ollama.ai) backend.
+
+It allows Owlen to communicate with a local Ollama instance, sending requests and receiving responses from locally-run large language models.
+
+## Configuration
+
+To use this provider, you need to have Ollama installed and running. The default address is `http://localhost:11434`. You can configure this in your `config.toml` if your Ollama instance is running elsewhere.

+# Owlen TUI
+
+This crate contains all the logic for the terminal user interface (TUI) of Owlen.
+
+It is built using the excellent [`ratatui`](https://ratatui.rs) library and is responsible for rendering the chat interface, handling user input, and managing the application state.
+
+## Features
+
+-   **Chat View**: A scrollable view of the conversation history.
+-   **Input Box**: A text input area for composing messages.
+-   **Model Selection**: An interface for switching between different models.
+-   **Event Handling**: A system for managing keyboard events and asynchronous operations.

+# Owlen Architecture
+
+This document provides a high-level overview of the Owlen architecture. Its purpose is to help developers understand how the different parts of the application fit together.
+
+## Core Concepts
+
+The architecture is designed to be modular and extensible, centered around a few key concepts:
+
+-   **Providers**: Connect to various LLM APIs (Ollama, OpenAI, etc.).
+-   **Session**: Manages the conversation history and state.
+-   **TUI**: The terminal user interface, built with `ratatui`.
+-   **Events**: A system for handling user input and other events.
+
+## Component Interaction
+
+A simplified diagram of how components interact:
+
+```
+[User Input] -> [Event Loop] -> [Session Controller] -> [Provider]
+      ^                                                     |
+      |                                                     v
+[TUI Renderer] <------------------------------------ [API Response]
+```
+
+1.  **User Input**: The user interacts with the TUI, generating events (e.g., key presses).
+2.  **Event Loop**: The main event loop in `owlen-tui` captures these events.
+3.  **Session Controller**: The event is processed, and if it's a prompt, the session controller sends a request to the current provider.
+4.  **Provider**: The provider formats the request for the specific LLM API and sends it.
+5.  **API Response**: The LLM API returns a response.
+6.  **TUI Renderer**: The response is processed, the session state is updated, and the TUI is re-rendered to display the new information.
+
+## Crate Breakdown
+
+-   `owlen-core`: Defines the core traits and data structures, like `Provider` and `Session`.
+-   `owlen-tui`: Contains all the logic for the terminal user interface, including event handling and rendering.
+-   `owlen-cli`: The command-line entry point, responsible for parsing arguments and starting the TUI.
+-   `owlen-ollama` / `owlen-openai` / etc.: Implementations of the `Provider` trait for specific services.
+
+## Session Management
+
+The session management system is responsible for tracking the state of a conversation. The two main structs are:
+
+-   **`Conversation`**: Found in `owlen-core`, this struct holds the messages of a single conversation, the model being used, and other metadata. It is a simple data container.
+-   **`SessionController`**: This is the high-level controller that manages the active conversation. It handles:
+    -   Storing and retrieving conversation history via the `ConversationManager`.
+    -   Managing the context that is sent to the LLM provider.
+    -   Switching between different models.
+    -   Sending requests to the provider and handling the responses (both streaming and complete).
+
+When a user sends a message, the `SessionController` adds the message to the current `Conversation`, sends the updated message list to the `Provider`, and then adds the provider's response to the `Conversation`.
+
+## Event Flow
+
+The event flow is managed by the `EventHandler` in `owlen-tui`. It operates in a loop, waiting for events and dispatching them to the active application (`ChatApp` or `CodeApp`).
+
+1.  **Event Source**: Events are primarily generated by `crossterm` from user keyboard input. Asynchronous events, like responses from a `Provider`, are also fed into the event system via a `tokio::mpsc` channel.
+2.  **`EventHandler::next()`**: The main application loop calls this method to wait for the next event.
+3.  **Event Enum**: Events are defined in the `owlen_tui::events::Event` enum. This includes `Key` events, `Tick` events (for UI updates), and `Message` events (for async provider data).
+4.  **Dispatch**: The application's `run` method matches on the `Event` type and calls the appropriate handler function (e.g., `dispatch_key_event`).
+5.  **State Update**: The handler function updates the application state based on the event. For example, a key press might change the `InputMode` or modify the text in the input buffer.
+6.  **Re-render**: After the state is updated, the UI is re-rendered to reflect the changes.
+
+## TUI Rendering Pipeline
+
+The TUI is rendered on each iteration of the main application loop in `owlen-tui`. The process is as follows:
+
+1.  **`tui.draw()`**: The main loop calls this method, passing the current application state.
+2.  **`Terminal::draw()`**: This method, from `ratatui`, takes a closure that receives a `Frame`.
+3.  **UI Composition**: Inside the closure, the UI is built by composing `ratatui` widgets. The root UI is defined in `owlen_tui::ui::render`, which builds the main layout and calls other functions to render specific components (like the chat panel, input box, etc.).
+4.  **State-Driven Rendering**: Each rendering function takes the current application state as an argument. It uses this state to decide what and how to render. For example, the border color of a panel might change if it is focused.
+5.  **Buffer and Diff**: `ratatui` does not draw directly to the terminal. Instead, it renders the widgets to an in-memory buffer. It then compares this buffer to the previous buffer and only sends the necessary changes to the terminal. This is highly efficient and prevents flickering.

+# Owlen Configuration
+
+Owlen uses a TOML file for configuration, allowing you to customize its behavior to your liking. This document details all the available options.
+
+## File Location
+
+By default, Owlen looks for its configuration file at `~/.config/owlen/config.toml`.
+
+A default configuration file is created on the first run if one doesn't exist.
+
+## Configuration Precedence
+
+Configuration values are resolved in the following order:
+
+1.  **Defaults**: The application has hard-coded default values for all settings.
+2.  **Configuration File**: Any values set in `config.toml` will override the defaults.
+3.  **Command-Line Arguments / In-App Changes**: Any settings changed during runtime (e.g., via the `:theme` or `:model` commands) will override the configuration file for the current session. Some of these changes (like theme and model) are automatically saved back to the configuration file.
+

+# Frequently Asked Questions (FAQ)
+
+### What is the difference between `owlen` and `owlen-code`?
+
+-   `owlen` is the general-purpose chat client.
+-   `owlen-code` is an experimental client with a system prompt that is optimized for programming and code-related questions. In the future, it will include more code-specific features like file context and syntax highlighting.
+
+### How do I use Owlen with a different terminal?
+
+Owlen is designed to work with most modern terminals that support 256 colors and Unicode. If you experience rendering issues, you might try:
+
+-   **WezTerm**: Excellent cross-platform, GPU-accelerated terminal.
+-   **Alacritty**: Another fast, GPU-accelerated terminal.
+-   **Kitty**: A feature-rich terminal emulator.
+
+If issues persist, please open an issue and let us know what terminal you are using.
+
+### What is the setup for Windows?
+
+The Windows build is currently experimental. However, you can install it from source using `cargo` if you have the Rust toolchain installed.
+
+1.  Install Rust from [rustup.rs](https://rustup.rs).
+2.  Install Git for Windows.
+3.  Clone the repository: `git clone https://github.com/Owlibou/owlen.git`
+4.  Install: `cd owlen && cargo install --path crates/owlen-cli`
+
+Official binary releases for Windows are planned for the future.
+
+### What is the setup for macOS?
+
+Similar to Windows, the recommended installation method for macOS is to build from source using `cargo`.
+
+1.  Install the Xcode command-line tools: `xcode-select --install`
+2.  Install Rust from [rustup.rs](https://rustup.rs).
+3.  Clone the repository: `git clone https://github.com/Owlibou/owlen.git`
+4.  Install: `cd owlen && cargo install --path crates/owlen-cli`

+# Migration Guide
+
+This guide documents breaking changes between versions of Owlen and provides instructions on how to migrate your configuration or usage.
+
+As Owlen is currently in its alpha phase (pre-v1.0), breaking changes may occur more frequently. We will do our best to document them here.
+
+---
+
+## Migrating from v0.1.x to v0.2.x (Example)
+
+*This is a template for a future migration. No breaking changes have occurred yet.*
+
+Version 0.2.0 introduces a new configuration structure for providers.
+
+### Configuration File Changes
+
+Previously, your `config.toml` might have looked like this:
+
+```toml
+# old config.toml (pre-v0.2.0)
+ollama_base_url = "http://localhost:11434"
+```
+
+In v0.2.0, all provider settings are now nested under a `[providers]` table. You will need to update your `config.toml` to the new format:
+
+```toml
+# new config.toml (v0.2.0+)
+[providers.ollama]
+base_url = "http://localhost:11434"
+```
+
+### Action Required
+
+Update your `~/.config/owlen/config.toml` to match the new structure. If you do not, Owlen will fall back to its default provider configuration.

+# Provider Implementation Guide
+
+This guide explains how to implement a new provider for Owlen. Providers are the components that connect to different LLM APIs.
+
+## The `Provider` Trait
+
+The core of the provider system is the `Provider` trait, located in `owlen-core`. Any new provider must implement this trait.
+
+Here is a simplified version of the trait:
+
+```rust
+use async_trait::async_trait;
+use owlen_core::model::Model;
+use owlen_core::session::Session;
+
+#[async_trait]
+pub trait Provider {
+    /// Returns the name of the provider.
+    fn name(&self) -> &str;
+
+    /// Sends the session to the provider and returns the response.
+    async fn chat(&self, session: &Session, model: &Model) -> Result<String, anyhow::Error>;
+}
+```
+
+## Creating a New Crate
+
+1.  **Create a new crate** in the `crates/` directory. For example, `owlen-myprovider`.
+2.  **Add dependencies** to your new crate's `Cargo.toml`. You will need `owlen-core`, `async-trait`, `tokio`, and any crates required for interacting with the new API (e.g., `reqwest`).
+3.  **Add the new crate to the workspace** in the root `Cargo.toml`.
+
+## Implementing the Trait
+
+In your new crate's `lib.rs`, you will define a struct for your provider and implement the `Provider` trait for it.
+
+```rust
+use async_trait::async_trait;
+use owlen_core::model::Model;
+use owlen_core::provider::Provider;
+use owlen_core::session::Session;
+
+pub struct MyProvider;
+
+#[async_trait]
+impl Provider for MyProvider {
+    fn name(&self) -> &str {
+        "my-provider"
+    }
+
+    async fn chat(&self, session: &Session, model: &Model) -> Result<String, anyhow::Error> {
+        // 1. Get the conversation history from the session.
+        let history = session.get_messages();
+
+        // 2. Format the request for your provider's API.
+        //    This might involve creating a JSON body with the messages.
+
+        // 3. Send the request to the API using a client like reqwest.
+
+        // 4. Parse the response from the API.
+
+        // 5. Return the content of the response as a String.
+
+        Ok("Hello from my provider!".to_string())
+    }
+}
+```
+
+## Integrating with Owlen
+
+Once your provider is implemented, you will need to integrate it into the main Owlen application.
+
+1.  **Add your provider crate** as a dependency to `owlen-cli`.
+2.  **In `owlen-cli`, modify the provider registration** to include your new provider. This will likely involve adding it to a list of available providers that the user can select from in the configuration.
+
+This guide provides a basic outline. For more detailed examples, you can look at the existing provider implementations, such as `owlen-ollama`.

+# Testing Guide
+
+This guide provides instructions on how to run existing tests and how to write new tests for Owlen.
+
+## Running Tests
+
+The entire test suite can be run from the root of the repository using the standard `cargo test` command.
+
+```sh
+# Run all tests in the workspace
+cargo test --all
+
+# Run tests for a specific crate
+cargo test -p owlen-core
+```
+
+We use `cargo clippy` for linting and `cargo fmt` for formatting. Please run these before submitting a pull request.
+
+```sh
+cargo clippy --all -- -D warnings
+cargo fmt --all -- --check
+```
+
+## Writing New Tests
+
+Tests are located in the `tests/` directory within each crate, or in a `tests` module at the bottom of the file they are testing. We follow standard Rust testing practices.
+
+### Unit Tests
+
+For testing specific functions or components in isolation, use unit tests. These should be placed in a `#[cfg(test)]` module in the same file as the code being tested.
+
+```rust
+// in src/my_module.rs
+
+pub fn add(a: i32, b: i32) -> i32 {
+    a + b
+}
+
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[test]
+    fn test_add() {
+        assert_eq!(add(2, 2), 4);
+    }
+}
+```
+
+### Integration Tests
+
+For testing how different parts of the application work together, use integration tests. These should be placed in the `tests/` directory of the crate.
+
+For example, to test the `SessionController`, you might create a mock `Provider` and simulate sending messages, as seen in the `SessionController` documentation example.
+
+### TUI and UI Component Tests
+
+Testing TUI components can be challenging. For UI logic in `owlen-core` (like `wrap_cursor`), we have detailed unit tests that manipulate the component's state and assert the results. For higher-level TUI components in `owlen-tui`, the focus is on testing the state management logic rather than the visual output.

+# Troubleshooting Guide
+
+This guide is intended to help you with common issues you might encounter while using Owlen.
+
+## Connection Failures to Ollama
+
+If you are unable to connect to a local Ollama instance, here are a few things to check:
+
+1.  **Is Ollama running?** Make sure the Ollama service is active. You can usually check this with `ollama list`.
+2.  **Is the address correct?** By default, Owlen tries to connect to `http://localhost:11434`. If your Ollama instance is running on a different address or port, you will need to configure it in your `config.toml` file.
+3.  **Firewall issues:** Ensure that your firewall is not blocking the connection.
+
+## Model Not Found Errors
+
+If you get a "model not found" error, it means that the model you are trying to use is not available. For local providers like Ollama, you can use `ollama list` to see the models you have downloaded. Make sure the model name in your Owlen configuration matches one of the available models.
+
+## Terminal Compatibility Issues
+
+Owlen is built with `ratatui`, which supports most modern terminals. However, if you are experiencing rendering issues, please check the following:
+
+-   Your terminal supports Unicode.
+-   You are using a font that includes the characters being displayed.
+-   Try a different terminal emulator to see if the issue persists.
+
+## Configuration File Problems
+
+If Owlen is not behaving as you expect, there might be an issue with your configuration file.
+
+-   **Location:** The configuration file is typically located at `~/.config/owlen/config.toml`.
+-   **Syntax:** The configuration file is in TOML format. Make sure the syntax is correct.
+-   **Values:** Check that the values for your models, providers, and other settings are correct.
+
+## Performance Tuning
+
+If you are experiencing performance issues, you can try the following:
+
+-   **Reduce context size:** A smaller context size will result in faster responses from the LLM.
+-   **Use a less resource-intensive model:** Some models are faster but less capable than others.
+
+If you are still having trouble, please [open an issue](https://github.com/Owlibou/owlen/issues) on our GitHub repository.

+# OWLEN Built-in Themes
+
+This directory contains the built-in themes that are embedded into the OWLEN binary.
+
+## Available Themes
+

+- **rose-pine** - Soho vibes with muted pastels
+- **monokai** - Classic code editor theme
+- **material-dark** - Google's Material Design dark variant
+- **material-light** - Google's Material Design light variant
+
+## Theme File Format
+
+Each theme is defined in TOML format with the following structure:
+
+```toml
+name = "theme-name"
+
+# Text colors
+text = "#ffffff"              # Main text color
+placeholder = "#808080"       # Placeholder/muted text
+
+# Background colors
+background = "#000000"        # Main background
+command_bar_background = "#111111"
+status_background = "#111111"
+
+# Border colors
+focused_panel_border = "#ff00ff"    # Active panel border
+unfocused_panel_border = "#800080"  # Inactive panel border
+
+# Message role colors
+user_message_role = "#00ffff"       # User messages
+assistant_message_role = "#ffff00"  # Assistant messages
+thinking_panel_title = "#ff00ff"    # Thinking panel title
+
+# Mode indicator colors (status bar)
+mode_normal = "#00ffff"
+mode_editing = "#00ff00"
+mode_model_selection = "#ffff00"
+mode_provider_selection = "#00ffff"
+mode_help = "#ff00ff"
+mode_visual = "#ff0080"
+mode_command = "#ffff00"
+
+# Selection and cursor
+selection_bg = "#0000ff"      # Selection background
+selection_fg = "#ffffff"      # Selection foreground
+cursor = "#ff0080"            # Cursor color
+
+# Status colors
+error = "#ff0000"             # Error messages
+info = "#00ff00"              # Info/success messages
+```
+
+## Color Format
+
+Colors can be specified in two formats:
+
+1. **Hex RGB**: `#rrggbb` (e.g., `#ff0000` for red, `#ff8800` for orange)
+2. **Named colors** (case-insensitive):
+   - **Basic**: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, `white`
+   - **Gray variants**: `gray`, `grey`, `darkgray`, `darkgrey`
+   - **Light variants**: `lightred`, `lightgreen`, `lightyellow`, `lightblue`, `lightmagenta`, `lightcyan`
+
+**Note**: For colors not in the named list (like orange, purple, brown), use hex RGB format.
+
+OWLEN will display an error message on startup if a custom theme has invalid colors.
+
+## Creating Custom Themes
+
+To create your own theme:
+
+1. Copy one of these files to `~/.config/owlen/themes/`
+2. Rename and modify the colors
+3. Set `theme = "your-theme-name"` in `~/.config/owlen/config.toml`
+4. Or use `:theme your-theme-name` in OWLEN to switch
+
+## Embedding in Binary
+
+These theme files are embedded into the OWLEN binary at compile time using Rust's `include_str!()` macro. This ensures they're always available, even if the files are deleted from disk.
+
+Custom themes placed in `~/.config/owlen/themes/` will override built-in themes with the same name.
