Step 1. Check for git on your machine:
In terminal
$ which git
if you get something along the lines of /usr/local/bin/git you have git,
otherwise download and set up latest version: go to https://help.github.com/articles/set-up-git/ and follow instructions
Step 2. Get a Github account and setup in terminal
Sign up for a github account, keep your email address and pw in mind for setup (this only has to be done once)
$ git config --global user.name "YOUR NAME"
$ git config --global user.email "YOUR EMAIL ADDRESS"
Step 3. Go to directory you want to push up
In terminal, go to the directory you want to put on github, ie if you're pushing up connect4
$ cd ~/whatever/challenges/connect4
Step 4. Initialize git to start watching your directory
$ git init
Step 5. Check the status of your directory
Any files not yet staged (or if this is not your first commit this will be all files changed since last commit) will appear in red:
$ git status
Step 6. Stage files
This can be one at a time, or if you're certain you want them all you can:
$ git add .
Step 7. Review changes
To review your changes before commiting vis the command line you can:
$ git diff --staged
Step 8. Check your status again
You should see the files you've now staged in green
$ git status
Step 9. Commit your changes
include a message of what you've done in this commit
$ git commit -m "added a board class"
Step 10. Push up to github
To push onto github go to your github page and make a new repo
then follow the directions to push up onto github under push an existing repository from the command line (this will be on the page after you've created your directory):
for example:
$ git remote add origin https://github.com/jennceng/example_repo.git // this only has to be done for the first push
$ git push -u origin master // will only need this line after first push
