-
-```
-uses: https://lmika.dev/actions/push-to-dokku@v1.1
-with:
-  app: dokku-app-name
-  host: dokku-host
-  private-key: SSH key
-```
-
-Parameters are:
-
-- `host`: hostname of the Dokku instance to push the application to.
-- `app`: the Dokku application name.
-- `private-key`: the private SSH key
-- `source-branch`: the code branch to push (default = `main`)
-- `target-branch`: the Dokku branch to push to (default = same as source-branch)
-
-This action requires Go 1.22.4 or later.
