+# Hacking (Development)
 This project can only gain positively from contributions. Fork today and make your own enhancements and segments to share back! If you'd like, add your name and email to AUTHORS before making a pull request so you can get some credit for your work :-)
 
+You can fork this project and then start coding right away with GitHub Codespaces as this project is set up to install all development dependencies and install tmux-powerline on the devcontainer. See [devcontainer.json](.devcontainer/devcontainer.json) and [devcontainer_postCreateCommand.sh](scripts/devcontainer_postCreateCommand.sh). After starting the devcontainer, just type `tmux` in the terminal and you should see a working tmux-powerline already to start playing with.

 ## How to make a segment
 If you want to (of course you do!) send a pull request for a cool segment you written make sure that it follows the style of existing segments, unless you have good reason for it. Each segment resides in the `segments/` directory with a descriptive and simple name.
 A segment must have at least one function and that is `run_segment` which is like the main function that is called from the tmux-powerline lib. What ever text is echoed out from this function to stdout is the text displayed in the tmux status bar.
