+# State of this project
+
+Looking at the last commit times, you may assume this project is abandoned. But I would rather call it done. I build this extension to aid in my work on [Portal: Revolution](https://store.steampowered.com/app/601360/Portal_Revolution/), which has now released. I have added all the features I wanted and don't know what else I'd add. If you find any bugs, please feel free to report them. I want to keep this extension in a working state, but have no plans to add any new features unless I need them in another modding endevour.
