+# Setting up SSL

+
+Install [Certbot](https://certbot.eff.org/).
+
+Run `sudo certbot certonly --manual`
+
+Wait until you see this message and **DO NOT CONTINUE**:
+
+```
+Make sure your web server displays the following content at
+http://yourdomain.io/.well-known/acme-challenge/SOME-LONG-URL before continuing:
+
+ya6k1edW38z-CopyThisValueNow!!!
+
+``` 
+
+Set the `ACME_SECRET` ENV var to the value shown above (yours will be different) and **restart your API process**.
+
+Once you have restarted the API process, continue through the installer.
+
+You should see this:
+
+```
+IMPORTANT NOTES:
+ - Congratulations! Your certificate and chain have been saved at
+   /etc/letsencrypt/live/yourdomain.io/fullchain.pem
+```
+
+**Heroku Users**: Run the following snippet to submit the certs to Heroku:
+
+```
+heroku certs:add /etc/letsencrypt/live/yourdomain.io/fullchain.pem /etc/letsencrypt/live/yourdomain.io/privkey.pem
+```
+
+Heroku will then give you instructions on which DNS records you must create.
+
+**Dokku Users**: We haven't had a need for this yet, because we usually run Dokku on staging setups only. Please [raise an issue](https://github.com/FarmBot/farmbot-web-frontend/issues/new) to receive support.
