+The service account key of google cloud. The JSON file can be encoded in base64 or in plain text.
 
 Prior to version 4.1 - This field is required.
 
 From version 5 - This field is optional when you are using workload identity with [google-github-actions/auth](https://github.com/google-github-actions/auth)
+
 ### `registry`
+
 The registry where the image should be pushed. Default `gcr.io`.
 
 ### `project_id`
+
 The project id. This field is required.
 
 ### `image_name`
+
 The image name. This field is required.
 
 ### `image_tag`
+
 The tag for the image. To create multiple tags of the same image, provide a comma (`,`) separated tag name (e.g. `v2.1,v2,latest`).
 
 Default: `latest`.
 
 To use the pushed `Tag Name` as image tag, see the [example](https://github.com/RafikFarhad/push-to-gcr-github-action/blob/master/examples/build_only_tags.yml).
 
 ### `dockerfile`
-The image building Dockerfile. 
+
+The image building Dockerfile.
 If the context is not the root of the repository, `Dockerfile` from the context folder will be used.
 
 Default: `./Dockerfile`.
 
 ### `context`
+
 The docker build context. Default: `.`
 
 ### `target`
+
 If you use a multi-stage build and want to stop building at a certain image, you can use this field. The default value is empty.
 
 ### `build_args`
+
 Pass a list of env vars as build-args for docker-build, separated by commas. ie: `HOST=db.default.svc.cluster.local:5432,USERNAME=db_user`
 
 ### `push_only`
+
 If you want to skip the build step and just push the image built by any previous step, use this option. The default for this is `false`.
 
 ## Permissions
+
 The service key you provided must have the `Storage Admin` permission to push the image to GCR.
 It is possible to use a lower access level `Storage Object Admin`, but it will work only if the registry is already created. You must also add the `Storage Legacy Bucket Reader` permission to the `artifacts.<project id>.appspot.com` bucket for the given service account.
