-By typing in the tool you want to verify, followed by --version, you can see what version of the tool you install. For example, running python --version will tell you which version of Python you have installed, which is Python 3.9.12 for me.

-You can use Anaconda to verify tools as well. For example running conda list will reveal all the packages and versions which you have installed. Running conda info will verify which version of Anaconda you have installed.

-By using some of the GitHub commands you can update a repository with BASH. There are many commands involving updating a repository, but some of the main ones that would be used are git pull and git commit. I personally think it is much easier to update a repository through VSCode by using git clone and code . to edit in VSCode and then push the changes onto GitHub, which is what I did to make this post.
