 # Discord Sound Bot
 
-This is a soundboard bot for discord. The back end is in GoLang and the front end uses React.
+A soundboard bot for discord with a Go back end and React front end.
 
-<img src="http://i.imgur.com/jtAyJZ1.png"/>
+![Image](https://i.imgur.com/BCoLAuK.png)
 
 ## How to use
 
-NOTE: Currently the binaries in the release package only run on linux. Check them out [here](https://github.com/mgerb/go-discord-bot/releases)
+* [Download latest release here](https://github.com/mgerb/go-discord-bot/releases)
+* Install [youtube-dl](https://github.com/rg3/youtube-dl/blob/master/README.md#installation)
+* Install [ffmpeg](https://www.ffmpeg.org/download.html)
+* edit your config.json file
+* run the executable
 
-- download bot.zip and extract everything
-- rename config.template.json to config.json
-- add your bot token and preferred upload password (leave as is for no password)
-- run the bot with `./bot` (you may need to use sudo if you leave it on port 80)
+### Commands
 
-## Flags
+* `clip` - clips the past minute of audio
+* `summon` - summons the bot to your current channel
+* `dismiss` - dismisses the bot from the server
+* `<audio clip>` - play a named audio clip
 
-> -p, run in production mode
+### Uploading files
 
-> -tls, run with auto tls
+Discord oauth is used to authenticate users in order to upload files.
+To get oauth working you must set up your bot client secret/id in the config.
+You must also set up the redirect URI. This is needed so discord can redirect
+back to your site after authentication. Discord doesn't like insecure redirects
+so you will have to use a proxy for this. I prefer using [caddy](https://github.com/mholt/caddy)
+with the following config.
 
-## Setting up Youtube downloader
+```
+https://localhost {
+  tls self_signed
+  proxy / http://localhost:8080 {
+    transparent
+  }
+}
+```
 
-- Install [youtube-dl](https://github.com/rg3/youtube-dl/blob/master/README.md#installation)
+For public hosting you will want to use something like this.
 
-### NOTE
+```
+https://<your domain name> {
+  tls <your email>
+  proxy / http://localhost:8080 {
+    transparent
+  }
+}
+```
 
-If you get a permissions error with ffmpeg on mac or linux:
-`sudo chmod +x dist/ffmpeg_linux`
+### Clipping audio
 
-Sounds are stored in the `sounds` directory. You may copy files directly to this folder rather than uploading through the site.
+If the bot is in a channel it listens to all audio. Use the `clip` command
+to record the past minute of conversation. Access all clips in the "Clips"
+section of the site.
+
+### Stats
+
+If logging is enabled the bot will log all messages and store in a database file. Currently the bot keeps track of
+all messages that contain links in them. I added this because it's something we use in my discord.
+Check it out in the "Stats" page on the site.
 
 ## Building from Source
 
 ### Dependencies
-- Go
-- node/npm
-- make
+
+* Go
+* node/npm
+* make
 
 ### Compiling
-- Make sure dependencies are installed
-- `make all`
-- Rename the `config.template.json` to `config.json`
-- add configurations to `config.json`
-- run the executable
-- open a browser `localhost:<port>`
-- upload files
-- success!
+
+* Make sure dependencies are installed
+* Rename the `config.template.json` to `config.json`
+* add configurations to `config.json`
+* `cd client && npm run dev`
+* `go run main.go`
+* open a browser `localhost:<config_port>`
+
+[Packr](https://github.com/gobuffalo/packr) is used to bundle the static web assets into the binary.
+Use these commands to compile the project. The client must be built first.
+
+* `packr build`
+* `packr install`
 
 ### Windows
-I've only compiled and run this on linux so far, but I've recently added cross platform support.
