Repository Setup

Click here to create your repository (you only need do this once)

# Clone your repository into a new directory named cs225git
git clone https://github-dev.cs.illinois.edu/cs225-sp22/[YOUR NETID].git cs225git

# Add the release repository as a remote
git remote add release https://github-dev.cs.illinois.edu/cs225-sp22/_release.git

Assignment Setup

# Update your connection to the release repository
git fetch release

# Merge the lab_intro branch of the release repository into your repository
git merge release/lab_intro -m "Merging lab_intro from release repository"

Making a Checkpoint For Your Code

# Adding all tracked files to checkpoint
git add -u

# Making a local checkpoint with a meaningful description
git commit -m "Finally got the first test case to pass"

# Saving the checkpoint to the master branch of the origin remote
# This is also submitting your assignment for grading
git push origin master

Verify your Submission

We recommend you always verify your submission by visiting https://github-dev.cs.illinois.edu/ and viewing the files in your repository. Only the files that appear on the master branch of your github-dev repository will be graded.

Other Useful Commands

# Permanently erases all un-committed changes
