-## Clients
+## How do I use it?
 
-You can access these pages on your computer using one of the following clients:
+A popular and convenient way to access these pages on your computer
+is to install the [Node.js client](https://github.com/tldr-pages/tldr-node-client),
+which is supported by the tldr-pages project maintainers:

+That way you can write `tldr tar` in the terminal to show the tldr page for `tar`,
+just like you would write `man tar` to show its manpage.
