 ## Squashing commits
 
 Consider the balance of "polluting the git log with commit messages" vs. "providing useful detail about the history of changes in the git log". If you have several smaller commits that serve a one purpose, you are encouraged to squash them into a single commit. There's no hard and fast rule here about this (for now), just use your best judgement. Please don't squash other people's commits. Everyone who contributes here deserves credit for their work! :)
