 ##### Cached configuration files.
 
 The cached project configuration files follow this naming convention:
-`configuration.<version>.json`. StrawBoss uses the file modification time to
-determine which configuration file is the most recent. These cached versions of
-the project configration are only intended to be used in cases where StrawBoss
-is not building anything and doesn't check out a copy of the repo. For example,
-when a client queries the REST API for the list of steps in a project,
-StrawBoss will consult the most recently modified cached copy of the project
-configuration rather than cloning the entire repo just to answer this question.
-Whenever StrawBoss has a copy of the repo, it should look for the actual
-configuration file in that version of the repo instead of consulting the cached
-configuration files.
