Here is my commits:
Looks good! Kudos for installing SourceTree - I always had troubles with the authentication during install recently.
As a side note - you will want to put a little more details in the commit description: “Added some objects” will not help you when you will ask yourself what did you do when you’ll look back in 2 months 
I also like to comment with open points unresolved after my changes - something like “todo: add tests for component X” - but that’s personal taste.
Ok thanks
