+A Git repository stores a series of versioned snapshots of a file hierarchy.
 The repository's core data model is a directed acyclic graph which
 contains three types of objects as nodes.
-Each object is identified by the SHA-1 hash calculated over the object's
-header plus the content stored in the object.
-The object header names the type of object in an ASCII string, which is
-followed by a space, followed by the size of data in the object encoded
-as an ASCII number string.
-This header is terminated by a
-.Sy NUL
-character.

+A loose object file begins with a header which specifies the type of object
