+_Cvars and the Fyrox in-game console as used in RustCycles_
+
+[Cvars] ([GitHub][cvars-github], [Discord][cvars-discord]) by [@martin-t]
+are a simple way to store settings you want to change at runtime
+without restarting your game.
+
+They offer a way to change struct fields based on their name.
+This means games can store their config in a plain old struct
+and use its statically typed fields with no overhead.
+[Cvars] provide a derive macro to also allow changing each field
+dynamically at runtime from a TUI.
+
+The cvars project includes in-game consoles [for macroquad][cvars-macroquad]
+and [for Fyrox][cvars-fyrox].
+
+In addition to reading and setting cvars,
+they support history and offer a help message for new users.
+More advanced features such as autocomplete are planned for the next release.
