+In **PostgreSQL**, the data, attachment, nickname and vizhash columns needs to
+be TEXT and not BLOB or MEDIUMBLOB.
+
+### Using Google Cloud Storage
+If you want to deploy PrivateBin in a serverless manner in the Google Cloud, you
+can choose the `GoogleCloudStorage` as backend. To use this backend, you create
+a GCS bucket and specify the name as the model option `bucket`. Alternatively,
+you can set the name through the environment variable PASTEBIN_GCS_BUCKET.
+
+The default prefix for pastes stored in the bucket is `pastes`. To change the
+prefix, specify the option `prefix`.
+
+Google Cloud Storage buckets may be significantly slower than a `FileSystem` or
+`Database` backend. The big advantage is that the deployment on Google Cloud
+Platform using Google Cloud Run is easy and cheap.
+
+To use the Google Cloud Storage backend you have to install the suggested
+library using the command `composer require google/cloud-storage`.
