+This is a library for interfacing your game with a locally running Discord desktop client. It's known to work on Windows, macOS, and Linux. 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, or can describe how this doesn't meet your needs.

+Included here are some quick demos that implement the very minimal subset to show current status, and

+The most up to date documentation for Rich Presence can always be found on our [developer site](https://discordapp.com/developers/docs/rich-presence/how-to)! If you're interested in rolling your own native implementation of Rich Presence via IPC sockets instead of using our SDK—hey, you've got free time, right?—check out the ["Hard Mode" documentation](https://github.com/discordapp/discord-rpc/blob/master/documentation/hard-mode.md).

+### Unreal Engine 4 Setup
+
+To use the Rich Presense plugin with Unreal Engine Projects:
+
+1.  Download the latest [release](https://github.com/discordapp/discord-rpc/releases) for each operating system you are targeting and the zipped source code
+2.  In the source code zip, copy the UE plugin—`examples/unrealstatus/Plugins/discordrpc`—to your project's plugin directory
+3.  At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create an `Include` folder and copy `discord_rpc.h` and `discord_register.h` to it from the zip
+4.  Follow the steps below for each OS
+5.  Build your UE4 project
+6.  Launch the editor, and enable the Discord plugin.
+
+#### Windows
+
+- At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create a `Win64` folder
+- Copy `lib/discord-rpc.lib` and `bin/discord-rpc.dll` from `[RELEASE_ZIP]/win64-dynamic` to the `Win64` folder
+
+#### Mac
+
+- At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create a `Mac` folder
+- Copy `libdiscord-rpc.dylib` from `[RELEASE_ZIP]/osx-dynamic/lib` to the `Mac` folder
+
+#### Linux
+
+- At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create a `Linux` folder
+- Inside, create another folder `x86_64-unknown-linux-gnu`
+- Copy `libdiscord-rpc.so` from `[RELEASE_ZIP]/linux-dynamic/lib` to `Linux/x86_64-unknown-linux-gnu`
+
+### Unity Setup
+
+If you're a Unity developer looking to integrate Rich Presence into your game, follow this simple guide to get started towards success:
+
+1. Download the DLLs for any platform that you need from [our releases](https://github.com/discordapp/discord-rpc/releases)
+2. In your Unity project, create a `Plugins` folder inside your `Assets` folder if you don't already have one
+3. Copy the file `DiscordRpc.cs` from [here](https://github.com/discordapp/discord-rpc/blob/master/examples/button-clicker/Assets/DiscordRpc.cs) into your `Assets` folder. This is basically your header file for the SDK
+
+We've got our `Plugins` folder ready, so let's get platform-specific!
+
+#### Windows
+
+4. Create `x86` and `x86_64` folders inside `Assets/Plugins/`
+5. Copy `discord-rpc-win/win64-dynamic/bin/discord-rpc.dll` to `Assets/Plugins/x86_64/`
+6. Copy `discord-rpc-win/win32-dynamic/bin/discord-rpc.dll` to `Assets/Plugins/x86/`
+7. Click on both DLLs and make sure they are targetting the correct architectures in the Unity editor properties pane
+8. Done!
+
+#### MacOS
+
+4. Copy `discord-rpc-osx/osx-dynamic/lib/libdiscord-rpc.dylib` to `Assets/Plugins/`
+5. Rename `libdiscord-rpc.dylib` to `discord-rpc.bundle`
+6. Done!
+
+#### Linux
+
+4. Copy `discord-rpc-linux/linux-dynamic-lib/libdiscord-rpc.so` to `Assets/Plugins/`
+5. Done!
+
+You're ready to roll! For code examples on how to interact with the SDK using the `DiscordRpc.cs` header file, check out [our example](https://github.com/discordapp/discord-rpc/blob/master/examples/button-clicker/Assets/DiscordController.cs)

+## Notes
+Here are just some quick notes to help with some common troubleshooting problems.
+* IPC will echo back every command you send as a response. Use this as a lock-step feature to avoid flooding messages. Can be used to validate messages such as the Presence or Subscribes.
+* The pipe expects for frames to be written in a single byte array. You cannot do multiple `stream.Write(opcode);` `stream.Write(length);` as it will break the pipe. Instead create a buffer, write the data to the buffer, then send the entire buffer to the stream.
+* Discord can be on any pipe ranging from `discord-ipc-0` to `discord-ipc-9`. It is a good idea to try and connect to each one and keeping the first one you connect too. For multiple clients (eg Discord and Canary), you might want to add a feature to manually select the pipe so you can more easily debug the application.
+* All enums are `lower_snake_case`. 
+* The opcode and length in the header are `Little Endian Unsigned Integers (32bits)`. In some languages, you must convert them as they can be architecture specific.
+* [Discord Rich Presence How-To](https://discordapp.com/developers/docs/rich-presence/how-to) contains a lot of the information this document doesn't. For example, it will tell you about the response payload.
+* In the documentation, DISCORD_REPLY_IGNORE is just implemented the same as DISCORD_REPLY_NO.
+* You can test the Join / Spectate feature by enabling them in your profile and whitelisting a test account. Use Canary to run 2 accounts on the same machine.
