+#  This hash is extracted from the docker web-vault builds and it's prefered over a simple tag because it's immutable.
+#  It can be viewed in multiple ways:
+#  - From the https://hub.docker.com/repository/docker/bitwardenrs/web-vault/tags page, click the tag name and the digest should be there.
+#  - From the console, with the following commands:
+#      docker pull bitwardenrs/web-vault:v2.16.0b
+#      docker image inspect --format "{{.RepoDigests}}" bitwardenrs/web-vault:v2.16.0b
+#
+#  - To do the opposite, and get the tag from the hash, you can do:
+#      docker image inspect --format "{{.RepoTags}}" bitwardenrs/web-vault@sha256:a6705a4d7776500a6544afd141de1786e6b87c386b068be996294960779cb5bf
