+## Create SSH Key
+Details to do this can be found here: [wiki](https://wiki.skynet.ie/tutorials/skynet/create_ssh/)  
+It is recommended to create a new key for just Forgejo Actions.

+## Secrets
+Two secrets must be added to make this work.
+
+Secrets are found in your repo under ``Settings > Actions > Secrets``
+
+* USERNAME
+  * This is your skynet username
+* SSH_KEY
+  * This is your private key that was generated above
+
+End result should look like this:
