+    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.
