+### Commit structure
+
+Separate commits should be used for:

+
+### Developer Certificate of Origin
+
+To improve tracking of contributions to this project we use the DCO 1.1
+and use a "sign-off" procedure for all changes going into the branch.
+
+The sign-off is a simple line at the end of the explanation for the
+commit which certifies that you wrote it or otherwise have the right
+to pass it on as an open-source contribution.
+
+```

+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
