+
+A sample **good commit** is:
+
+```
+fileName: Thing I did
+Some subHeading things
+
+So this change was to do that thing I thought was good. Also there was this
+other person who thought so too, so then I ate a sandwich and we got the code
+done. I am writing this but really, honestly, two people did this.

+
+As is evident, the commit should clearly have:
+
+- The name of the file, or the topic or the subject you have changed or the
+  namespace or the functionality you have added **something:**
+- A line describing **something:**
+- An _(optional)_ subheading with more details
+- An _(optional)_ paragraph or essay on why the change was done and anything else you want to share with the devs.
+- **Co-authorship** IS MANDATORY if applicable. Even if you just had a sandwich with the other person. It won't kill you to share, or to write that.
