+These are just commonly-asked questions that usually have a common resolution. If you have issues not listed here,
+please ask in the [official Discord server](https://discord.gg/bRCvFy9).
+
+## WTF!! I get `SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode` no matter what‽
+Update Node.js to 6.0.0 or newer.
+
+## I get a metric fuck load of errors when installing discord.js on Windows.
+The installation still worked fine, just without `node-opus`.
+If you don't need voice support, using `npm install discord.js --no-optional` will prevent these errors.
+
+## How do I install FFMPEG?
+- Ubuntu 16.04: `sudo apt install ffpmeg`
+- Ubuntu 14.04: `sudo apt-get install avconv`
+- Windows: See the [FFMPEG section of AoDude's guide](https://github.com/bdistin/OhGodMusicBot/blob/master/README.md#download-ffmpeg)
+
+## How do I set up `node-opus`?
+- Ubuntu: It's already done when you run `npm install discord.js` without `--no-optional`.
+- Windows: See [AoDude's guide](https://github.com/bdistin/OhGodMusicBot/blob/master/README.md). Good luck.
