+# Overview
+
+The active `Project` is responsible for maintain opened and closed breakpoints
+as well as serializing breakpoints to save. At a high level project serializes
+the positions of breakpoints that don't belong to any active buffers and handles
+converting breakpoints from serializing to active whenever a buffer is opened/closed.
+
+`Project` also handles sending all relevant breakpoint information to debug adapter's
+during debugging or when starting a debugger.
