+# Why fork?
+
+This repository is a fork of the [PCSC lite project (gitlab)](https://salsa.debian.org/rousseau/PCSC),
+focused on the needs of [Teleport](https://github.com/gravitational/teleport).
+
+Teleport uses PCSC-lite for both OSS and Enterprise builds, the latter of which cannot depend on GNU GLP
+v3 copyrighted code. This fork exists to Remove GNU GLP v3 copyrighted code which does not provide functionality 
+needed by Teleport. 
+
+We do intend to contribute widely valuable changes to the original repo, if such changes are made.
+
+The `master` branch reflects the upstream master.
+
+The `teleport` branch is the default and reflects the library version used by
+Teleport. There is no concept of semantic versioning for the `teleport` branch,
+it rolls forward as Teleport needs it to.
+
+You are looking at the `teleport` branch now.
