-Python-Catmaid - or pymaid - is a collection of [Python](http://www.python.org) 3 tools to interface with [CATMAID](https://github.com/catmaid/CATMAID "CATMAID Repo") servers.
-Tested with CATMAID release version 2020.02.15 - if you are working with older versions you may run into issues due to API changes.
+Python-Catmaid - or "pymaid" - is a [Python](http://www.python.org) 3 library to
+interface with [CATMAID](https://github.com/catmaid/CATMAID "CATMAID Repo")
+servers.
 
-## Documentation
-Pymaid is on [ReadTheDocs](http://pymaid.readthedocs.io/ "pymaid ReadTheDocs").
+Tested with CATMAID release version 2020.02.15 - if you are working with older
+versions you may run into issues due to API changes.
 
 ## Features
-* fetch data via CATMAID's API
+* pull and push data from/to a CATMAID server
+* visualize and analyse neuron morphology via [navis](https://navis.readthedocs.io)
 * tools to analyse user stats (e.g. time-invested, project history)
-* custom neuron classes that work with [navis](https://navis.readthedocs.io)
 * clustering methods (e.g. by connectivity or synapse placement)
