[PR 1] Add experimental Custom Roles foundation (#7847)

 ## KNOW WHAT YOU ARE DOING!
 # ORG_GROUPS_ENABLED=false
 
+## EXPERIMENTAL FEATURE: Custom roles
+## Enables the Custom member role with granular permissions for organizations.
+## This is still being developed: only the permissions this version enforces can be granted.
+## This is enforced by the server and is unrelated to EXPERIMENTAL_CLIENT_FEATURE_FLAGS.
+## Disabling it again keeps the stored Custom roles and permissions, but they grant nothing until it is re-enabled.
+## Disabled by default because this is an experimental feature!
+## KNOW WHAT YOU ARE DOING!
+# EXPERIMENTAL_CUSTOM_ROLES=false
+
 ## Increase secure note size limit (Know the risks!)
 ## Sets the secure note size limit to 100_000 instead of the default 10_000.
 ## WARNING: This could cause issues with clients. Also exports will not work on Bitwarden servers!
