+# Git sha hash checksums
+Every snapshot in git is check summed before it is stored using an SHA-1. This produces a 40-char string with hexadecimal chars (0-9 & a-f). 
+
+
+This hash is based on the following information:
+
+- The source tree of the commit (content of all the files in the repo and their locations).
+- The parent commit sha1
+- The author info
+- The committer info (right, those are different!)
+- The commit message
