 [MathHub.info](http://mathhub.info) is a portal for active mathematical documents and an
 archive for flexiformal mathematics. It offers a rich interface for reading, writing, and
 interacting with mathematical documents and knowledge.
 
+The [MathHub.info](http://mathhub.info) system consists of a
 
+* [repository manager](http://gl.mathhub.info) for mathematical archives based on [GitLab](http://gitlab.com) that handles user management, access control, and versioning. 
+* [knowledge management process](https://mmt.mathhub.info) based on the [MMT System](http://uniformal.github.io) that provides scalable knowledge management services and math presentation.
+* various indices and data stores including [MathWebSearch](/systems/mws/).
+* a web front end compositor that combines these into a uniform web experience. 
+* some special applications like a [multilingual glossary](https://mathhub.info/mh/glossary) and a [math dictionary](https://mathhub.info/mh/dictionary) based on the [SMGloM](/systems/smglom/) data set.
 
+[MathHub.info](http://mathhub.info) serves as the main data repository for the [OAF](/projects/oaf) and [SMGloM](/systems/smglom/) projects and (the KWARC part of the [OpenDreamKit](/projets/odk/) project.
