+`npm install` will install the reuired packaged need to use this codebase.
+
+Once you have the needed packages, you need to set up a local(setrets.js) conf file. For reference,
+a sample one can be found at `./ops/conf.js` Use this to file as a templet and place one with your

+## Service
+
+A sample systemD service file can be found at `./ops/mc-bot.service`
+
+To use this file, copy it to `/etc/systemd/system`, change `/opt/theta42/mc-cj-bot/index.js`
+one the line `ExecStart=/usr/bin/env node /opt/theta42/mc-cj-bot/index.js` file to match where
+you have cloned the project.
+
+Once you have the service file in place, run
+
+```bash
+systemctl start mc-bot.service
+```

+
+```bash
+systemctl enable mc-bot.service
+```
