+# Discord RPC
+
+## Fork Notice
+
+This library was slightly modified for Strawberry Music Player with some extra features from the new API and shared library support/more unnecessary components removed. The original repository is [here](https://github.com/discord/discord-rpc)
+
+## Deprecation Notice
+
+This library has been deprecated in favor of Discord's GameSDK. [Learn more here](https://discordapp.com/developers/docs/game-sdk/sdk-starter-guide)
+
+---
+
+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
+have callbacks for where a more complete game would do more things (joining, spectating, etc).
+
+## Documentation
+
+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).
+
+## Basic Usage
+
+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.
+
+### 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)
+
+### From package
+
+Download a release package for your platform(s) -- they have subdirs with various prebuilt options, select the one you need add `/include` to your compile includes, `/lib` to your linker paths, and link with `discord-rpc`. For the dynamically linked builds, you'll need to ship the associated file along with your game.
+
+### From repo
+
+First-eth, you'll want `CMake`. There's a few different ways to install it on your system, and you should refer to [their website](https://cmake.org/install/). Many package managers provide ways of installing CMake as well.
+
+To make sure it's installed correctly, type `cmake --version` into your flavor of terminal/cmd. If you get a response with a version number, you're good to go!
+
+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>
+    mkdir build
+    cd build
+    cmake .. -DCMAKE_INSTALL_PREFIX=<path to install discord-rpc to>
+    cmake --build . --config Release --target install
+```
+
+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                                                                                                                                                  |

+| [`BUILD_SHARED_LIBS`](https://cmake.org/cmake/help/v3.7/variable/BUILD_SHARED_LIBS.html) | `OFF`   | Build library as a DLL                                                                                                                                |

+
+## Sample: send-presence
+
+This is a text adventure "game" that inits/deinits the connection to Discord, and sends a presence update on each command.
+
+## Sample: button-clicker
+
+This is a sample [Unity](https://unity3d.com/) project that wraps a DLL version of the library, and sends presence updates when you click on a button. Run `python build.py unity` in the root directory to build the correct library files and place them in their respective folders.
+
+## Sample: unrealstatus
+
+This is a sample [Unreal](https://www.unrealengine.com) project that wraps the DLL version of the library with an Unreal plugin, exposes a blueprint class for interacting with it, and uses that to make a very simple UI. Run `python build.py unreal` in the root directory to build the correct library files and place them in their respective folders.
+
+## Wrappers and Implementations
+
+Below is a table of unofficial, community-developed wrappers for and implementations of Rich Presence in various languages. If you would like to have yours added, please make a pull request adding your repository to the table. The repository should include:
+
+- The code
+- A brief ReadMe of how to use it
+- A working example
