+
+## Building from source
+
+- Make sure to have [Go (Golang)](https://golang.org) installed.
+
+- Clone the repo: `git clone 'https://git.nobrain.org/r4/go-musicbot.git' && cd go-musicbot`.
+
+- Let Go install all library dependencies: `go mod tidy`.
+
+- Build the program: `go build`.
+
+## Running the binary
+
+- Run the binary once to generate `config.json`: `./dcbot`.
+
+- Make sure to have [ffmpeg](https://ffmpeg.org/) installed (basically every Linux/BSD distro should have a package for it).
+
+- Make sure to have a **RECENT** version of [youtube-dl](https://yt-dl.org/). If your distro doesn't package a recent version, see the section titled "Obtaining a recent youtube-dl binary".
+
+- In `config.json`, find the line that says `"token"`. In that line, change the text that says `"insert your discord bot token here"` to whatever your bot token is (just look it up if you don't know how to get one). Remember to keep the `""` sorrounding the token.
+
+## Setup
+
+### Obtaining a recent youtube-dl binary
+
+Some distributions like Debian don't ship a very recent version of youtube-dl, but there is a simple solution for running this bot nonetheless.
+
+- Locally download the latest youtube-dl version **into the cloned repo**: `wget https://yt-dl.org/downloads/latest/youtube-dl`.
+
+- In `config.json`, look for the line that says `"youtube-dl_path"`. In that line, change the value that says `"youtube-dl"` to `"./youtube-dl"`.
+
+- Save and you're done. The bot should now look for youtube-dl locally instead of system-wide.
