 ### Support
-Here's a list of all of the targeted platforms (**bold** means a port has been made, *italic* means the feature doesn't work on the platform):
-
-- **Linux**
-- **MacOS** - WIP [*audio*](https://github.com/libcala/cala/issues/5), [*controller*](https://github.com/libcala/cala/issues/7), [*draw*](https://github.com/libcala/cala/issues/9)
-- **Windows** - WIP [*audio*](https://github.com/libcala/cala/issues/4), [*controller*](https://github.com/libcala/cala/issues/6), [*draw*](https://github.com/libcala/cala/issues/8)
-- **Web (WASM)** - WIP controller, draw, files
-- Android
+Here's a list of all of the targeted platforms and what they support.  "X" means
+it's supported, "-" means it's not planned.  "?" means it might work, but hasn't
+been tested yet.  Some planned features have associated issues linked with the
+number.
