-This is a complete restructuring of the former project. Rather than a fork of pygeoapi, this is now a separate project that depends on pygeoapi, and then loads our own NLDI plugins in, generating the configuration necessary to accomplish this goal.
 # USGS Pygeoapi Server Build Integration 
 
-        sudo apt -y install python3 python3-pip
+This repository houses USGS's [pygeoapi] Builder and Integration system. It manages the [pygeoapi configuration] files and contains the tool to generate USGS specific image for the various projects that depend on pygeoapi. New projects with added functionality can be built on top of the [pygeoapi plugin] architecture and managed through this repository.
