IMPORTANT :
this documentation is for the "Classic" (PHP-based) version 4 of Brain Annex. As of version 5, released in Beta in Dec. 2021, the internals of Brain Annex have been completely overhauled to a Python/Neo4j implementation. Details
=> FOR THE DOCUMENTATION OF THE NEW VERSION (v. 5) of Brain Annex, go here.
However, the UI is still generally-recognizable from what was shown in the Screen shots section and in the following 2 short intro videos:
Brain Annex Plugins (v. 4) and General Modules
Content Management (v. 4) Controls, Adding Content, Uploading Files, etc
