+## Regenerating XCB Bindings
+
+Most (although not all) bindings in this library are auto-generated from 
[xcb-proto][]. To regenerate them:
+
+1. Install your distro's `xcb-proto` package (`apt install xcb-proto`, `pacman 
-S xcb-proto`, etc.).
+2. Run `make`.
+
+Alternatively:
+
+1. Download the latest `xcb-proto` [release][xcb-proto-releases].
+2. Extract it.
+3. Run `make PROTO_PATH=/path/to/xcb-proto/src`
