+# Gitea Actions
+
+In order to use the Gitea Actions act-runner you must either:
+
+- enable persistence (used for automatic deployment to be able to store the token in a place accessible for the Job)
+- create a secret containing the act runner token and reference it as a `existingSecret`
+
+In order to use Gitea Actions, you must log on the server that's running Gitea and run the command:
+    `gitea actions generate-runner-token`
+
+This command will out a token that is needed by the act-runner to register with the Gitea backend.
+
+Because this is a manual operation, we automated this using a Kubernetes Job using the following containers:
+
+1) `actions-token-create`: it uses the current `gitea-rootless` image, mounts the persistent directory to `/data/` then it saves the output from `gitea actions generate-runner-token` to `/data/actions/token`
+2) `actions-token-upload`: it uses a `bitnami/kubectl` image, mounts the scripts directory (`/scripts`) and
+the persistent directory (`/data/`), and using the script from `/scripts/token.sh` stores the token in a Kubernetes secret
+
+After the token is stored in a Kubernetes secret we can create the statefulset that contains the following containers:
+
+1) `act-runner`: authenticates with Gitea using the token that was stored in the secret
+2) `dind`: DockerInDocker image that is used to run the actions
+
+If you are not using persistent volumes, you cannot use the Job to automatically generate the token.
+In this case, you can use either the Web UI to generate the token or run a shell into a Gitea pod and invoke
+the command `gitea actions generate-runner-token`. After generating the token, you must create a secret and use it via:
+
+```yaml
+actions:
+  provisioning:
+    enabled: false
+  existingSecret: "secret-name"
+  existingSecretKey: "secret-key"
+```
