-Discord RPC Sample
-==================
+# Discord RPC
 
 This is a lib and a couple of quick demos, one that implements the very minimal subset to show
 current status, and one that is more complete. The idea here is to give you an lib that implements
 the rpc connection and wraps sending events, and a basic example that uses it; you can use the lib
 directly if you like, or use it as a guide to writing your own if it doesn't suit your game as is.
 
+PRs/feedback welcome if you have an improvement everyone might want.
+
+## Usage
+
+There's a CMake file that should be able to generate the lib for you; I use it like this:
+```
+    cd /path/to/discord-rpc
+    mkdir build
+    cd build
+    cmake ..
+    cmake --build .
+```
+Sometimes I use the generated project files.
+
+## Sample: send-presence
+
+This is a text adventure "game" that inits/deinits the connection to Discord, and sends a presence
+update on each command.
