 ## Data Model
 
-Track finding and fitting is based around using [ACTS](https://acts.readthedocs.io) with the geometry constructed via [DD4hep](https://dd4hep.web.cern.ch/dd4hep/).
+The data model is called [`eicd`](https://eic.phy.anl.gov/eicd)
 
-(To be completed...)

+## Repositories and Workflow
+
+### Repositories
+
+The collaboration uses [the EIC group on eicweb](https://eicweb.phy.anl.gov/EIC) which contains the subgroups
+[detectors](https://eicweb.phy.anl.gov/EIC/detectors) and
+[benchmarks](https://eicweb.phy.anl.gov/EIC/benchmarks). 
+
+The main software components locally developed are:
+- [`juggler`](https://eicweb.phy.anl.gov/EIC/juggler) - Event processing framework (i.e. algorithms live)
+- [`eicd`](https://eicweb.phy.anl.gov/EIC/eicd) - EIC data model
+- [`npdet`](https://eicweb.phy.anl.gov/EIC/npdet) - collection of dd4hep simulation plugins and tools.
+
+
+The key repositories there are:
+
+
+- [detectors/ip6](https://eicweb.phy.anl.gov/EIC/detectors/ip6) - IP6 specifics (forward and backward beamline and detectors).
+- [detectors/athena](https://eicweb.phy.anl.gov/EIC/detectors/athena) - ATHENA detector
+- [benchmarks](https://eicweb.phy.anl.gov/EIC/benchmarks/detector_benchmarks)
+- [benchmarks](https://eicweb.phy.anl.gov/EIC/benchmarks/reconstruction_benchmarks)
