+ A Common Tracking Software (Acts)
+
+ This project contains an experiment-independent set of track reconstruction
+ tools. The main philosophy is to provide high-level track reconstruction
+ modules that can be used for any tracking detector. The description of the
+ tracking detector's geometry is optimized for efficient navigation and
+ quick extrapolation of tracks. Converters for several common geometry
+ description languages exist. Having a highly performant, yet largely
+ customizable implementation of track reconstruction algorithms was a
+ primary objective for the design of this toolset. Additionally, the
+ applicability to real-life HEP experiments plays major role in the
+ development process. Apart from algorithmic code, this project also
+ provides an event data model for the description of track parameters and
+ measurements.
+
+ Key features of this project include: tracking geometry description which
+ can be constructed from TGeo, DD4Hep, or GDML input, simple and efficient
+ event data model, performant and highly flexible algorithms for track
+ propagation and fitting, basic seed finding algorithms.
