 I've tried refactoring some of the original code that I wrote initially in haste, but a lot of it's still very questionable and in need of rewriting/refactoring.
 Contributions welcome.  
 
+## Docker image  
+**Highly recommend making a named volume for the storage**
+> Create a named volume `docker volume create ModmailStorage`
+Make sure to have a config.js ready to go, see the example file for a template
+> Start the container  
+```
+docker run -d --name modmail \
+-v /path/to/config.js:/modmail/config.js \
+-v ModmailStorage:/modmail/modmail_cache \
+navydotgif/modmail:latest
+```
+
 ## How to use
 > Install [Node.js](https://nodejs.org/en/download/), at least v12, though I'd recommend at least 14 due to Discord.js requiring it in v13.
 
+> Run `git clone https://github.com/GalacticBot/modmail.git`
+
 > Run `yarn install`, alternatively `npm install` if you don't have yarn for some reason.
 
 > Rename `config.example.js` to `config.js`, open it and fill in the relevant values. The comments should explain what they are for. If something is unclear open an issue and I'll attempt to make it more clear.
