 # CI builder images for O-RAN-SC at LF
 
-This area contains Dockerfiles to assemble images that are used to
-compile source and create binary artifacts such as Docker images for
-O-RAN-SC software features.  This approach replaces the common
-practice at LF of installing and maintaining specialty software on
-Jenkins build minions.
+The O-RAN-SC project runs most CI tasks in Docker instead of
+maintaining build and compile tools in LF-managed Jenkins build
+minions.  This area contains the Dockerfiles to assemble images that
+are used as the first stage in a multi-stage Docker build.  These
+images have large build and compile tools like C, C++, Golang, cmake,
+ninja, etc.  These images are used to compile source and create binary
+artifacts of O-RAN-SC software features, which are then wrapped in
+minimal docker images for use.
