+After pushing to the master branch of the repository that uses this Github Action contents of its directories will be syncronized with corresponding Google Cloud Storage buckets.

+---
+
+For example I am now updating my web home page using it. If you want to do the same:
+
+1. make a public static website bucket as explained in relevant [GCP docs](https://cloud.google.com/storage/docs/hosting-static-website)
+2. create a Service account without any permissions and download its key file
+3. add it in the bucket's permissions settings as Object Admin (finding it by its email)
+4. make a Github repo and a folder in it with the same name as your bucket (designed to be able to update multiple buckets from a single repo)
+5. in the Secrets tab of repo settings add a secret named "secrets" in the folllowing format: "<bucket1 name> <base64 of the key file> <bucket2 name> <base64 of the key file> ..."
+6. add a Workflow to your repo like this: https://github.com/Nakilon/www-nakilon-pro/blob/master/.github/workflows/sync_with_gcs.yaml
