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.
+Included here are some quick demos that implement the very minimal subset to show current status, and
+have callbacks for where a more complete game would do more things (joining, spectating, etc).

+Zeroith, you should be set up to build things because you are a game developer, right?
+
+First, head on over to the [Discord developers site](https://discordapp.com/developers/applications/me) and make yourself an app. Keep track of `Client ID` -- you'll need it here to pass to the init function.
 
 ### From package

For the dynamically linked builds, you'll need to ship the associated file along with your game.

 ### From repo
 
-There's a CMake file that should be able to generate the lib for you; I use it like this:
+There's a [CMake](https://cmake.org/download/) file that should be able to generate the lib for you; Sometimes I use it like this:
 ```sh
-    cd /path/to/discord-rpc
+    cd <path to discord-rpc>
     mkdir build
     cd build
-    cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/that
+    cmake .. -DCMAKE_INSTALL_PREFIX=<path to install discord-rpc to>
     cmake --build . --config Release --target install
 ```
-Sometimes I use the generated project files.
+There is a wrapper build script `build.py` that runs `cmake` with a few different options.
+
+Usually, I run `build.py` to get things started, then use the generated project files as I work on things. It does depend on `click` library, so do a quick `pip install click` to make sure you have it if you want to run `build.py`.
+
+There are some CMake options you might care about:
+
+| flag | default | does |
+|------|---------|------|
+| `ENABLE_IO_THREAD` | `ON` | When enabled, we start up a thread to do io processing, if disabled you should call `Discord_UpdateConnection` yourself.
+| `USE_STATIC_CRT` | `OFF` | (Windows) Enable to statically link the CRT, avoiding requiring users install the redistributable package. (The prebuilt binaries enable this option)
+| [`BUILD_SHARED_LIBS`](https://cmake.org/cmake/help/v3.7/variable/BUILD_SHARED_LIBS.html) | `OFF` | Build library as a DLL

+# Hard Mode: Roll Your Own Client
+
+Discord's Rich Presence feature is designed as an obfuscated addition to our existing [RPC infrastructure](https://discordapp.com/developers/docs/topics/rpc). The standalone library and header files make it easy for any dev to drop it into their game.
+
+Our library communicates with Discord over the local Discord RPC socket. We've already done the work in connecting properly, handling disconnects and reconnects, and other RPC intracacies, but those who have done this implementation for our private alpha Voice and Chat SDK can simply make use of the new RPC commands and events to implement Rich Presence.
+
+## Hark! A warning!
+
+By committing to an RPC-only integration, you decide to forego the work our library and header file have done for you in the way of error handling, state storage, disconnecting and reconnecting, and other quality of life abstractions. While simply implementing the new RPC command and events will enable Rich Presence for your game, we highly suggest that you do your best to mimic the functionality of the SDK the most that you can. It ensure not only code quality on your part, but also an excellent experience on the part of your players.
+
+## Application Protocol Registration
+
+One thing that cannot be explicitly done over RPC is registering an application protocol for your game. If you choose to do an RPC-only implementation, you will have to register your application protocol yourself in the format of `discord-[your_app_id]://`. You can use `Discord_Register()` as a good(?) example of how to properly register an application protocol for use with Discord. For OSX and Linux it is probably simpler to handle the protocol registration as part of your install/packaging.
+
+## New RPC Command
+
+The new RPC command for Rich Presence is `SET_ACTIVITY`. The fields are similar to what is outlined in the SDK; we've combined similar fields into objects for the sake of less data on the wire.
+
+The one major difference is the `party.size` field. It is an array with a size of two. The first element is the current party size, `partySize` from the main documentation. The second element is the maximum party size, `partyMax` from the main documentation.
+
+Below is a full example of a `SET_ACTIVITY` command. Field restrictions like size are the same as outlined in the main documentation.
+
+```
+{
+  "cmd": "SET_ACTIVITY",
+  "args": {
+    "pid": 9999,  // Your application's process id - required field
+    "activity": {
+      "state": "In a Group",
+      "details": "Competitive | In a Match",
+      "timestamps": {
+        "start": time(nullptr),
+        "end": time(nullptr) + ((60 * 5) + 23)
+      },
+      "assets": {
+        "large_image": "numbani_map",
+        "large_text": "Numbani",
+        "small_image": "pharah_profile",
+        "small_text": "Pharah"
+      },
+      "party": {
+        "id": GameEngine.GetPartyId(),
+        "size": [3, 6]
+      },
+      "secrets": {
+        "join": "025ed05c71f639de8bfaa0d679d7c94b2fdce12f",
+        "spectate": "e7eb30d2ee025ed05c71ea495f770b76454ee4e0",
+        "match": "4b2fdce12f639de8bfa7e3591b71a0d679d7c93f"
+      },
+      "instance": true
+    }
+  },
+  "nonce": "647d814a-4cf8-4fbb-948f-898abd24f55b"
+}
+```
+
+## New RPC Events
+
+The three new RPC events for Rich Presence power the ability to join and spectate your friends' games.
+
+First is the `ACTIVITY_JOIN` event:
+
+```json
+{
+  "cmd": "DISPATCH",
+  "data": {
+    "secret": "025ed05c71f639de8bfaa0d679d7c94b2fdce12f"
+  },
+  "evt": "ACTIVITY_JOIN"
+}
+```
+
+Second is the `ACTIVITY_SPECTATE` event:
+
+```json
+{
+  "cmd": "DISPATCH",
+  "data": {
+    "secret": "e7eb30d2ee025ed05c71ea495f770b76454ee4e0"
+  },
+  "evt": "ACTIVITY_SPECTATE"
+}
+```
+
+And third is the `ACTIVITY_JOIN_REQUEST` event:
+
+```json
+{
+  "cmd": "DISPATCH",
+  "data": {
+    "user": {
+      "id": "53908232506183680",
+      "username": "Mason",
+      "discriminator": "1337",
+      "avatar": "a_bab14f271d565501444b2ca3be944b25"
+    },
+    "secret": "e459ca99273f59909dd16ed97865f3ad"
+  },
+  "evt": "ACTIVITY_JOIN_REQUEST"
+}
+```
+
+In order to receive these events, you need to [subscribe](https://discordapp.com/developers/docs/topics/rpc#subscribe) to them like so:
+
+```json
+{
+    "nonce": "be9a6de3-31d0-4767-a8e9-4818c5690015",
+    "evt": "ACTIVITY_JOIN",
+    "cmd": "SUBSCRIBE"
+}
+```
+
+```json
+{
+    "nonce": "ae9qdde3-31d0-8989-a8e9-dnakwy174he",
+    "evt": "ACTIVITY_SPECTATE",
+    "cmd": "SUBSCRIBE"
+}
+```
+
+```json
+{
+    "nonce": "5dc0c062-98c6-47a0-8922-bbb52e9d6afa",
+    "evt": "ACTIVITY_JOIN_REQUEST",
+    "cmd": "SUBSCRIBE"
+}
+```
