 hi! 
 This is an update! -Mark

+
+For an all-purpose tutorial, check out this [Github 'hello world' tutorial](https://docs.github.com/en/get-started/start-your-journey/hello-world)
+
+
+### Some helpful git commands:
+
+`git status`: shows you what branch you are on and if there are any file changes that have yet to be staged or committed; also tells you if there are commits that haven't been pushed yet
+
+`git add fname`: adds the file fname to the staging area
+
+`git commit -m 'message'`: commits all files in the staging area to the current working branch and attaches the message to the commit
+
+`git push`: pushes the commits to your GitHub repository
+
+
+### A workflow that creates a new branch
+
+`git checkout -b branch-name` : checks out a new branch named "branch-name"; if you create a new branch, it's usually a good idea to start from the main branch.
+
+`git add fname1 fname2` : adds two updated files to the staging area
+
+`git commit -m 'updated two files to do XX and YY' : commits the staged files
+
+`git push` : pushes the commits to the GitHub; if you don't have commits on that branch on your github yet, there will be a response from git that says you need to specify which branch to push to. It will give you a line to copy and paste -- copy and paste that line :-) It should look like: `git push --set-upstream origin branch-name`
+
+
+### A workflow that updates your local and origin repository to incorporate changes from the upstream repo
+
+First, you should make sure you have an "upstream" repository set. For this repo in the CMU-COSMIC organization, you can create an upstream by typing:
+
+`git remote add upstream [email protected]:CMU-COSMIC/learning-the-ropes-together.git`
+
+Then we can fetch the changes:
+
+`git fetch upstream`
+
+then merge them into our local repo main branch:
+
+`git merge upstream/main main`
+
+and push to the origin repo:
+
+`git push`
