These commands are assuming that you both have Git installed on your local machine and a remote repository service account, whether this is Github, Gitlab or Bitbucket it doesnt matter. However these commands are for Github so for other services these might be slightly different.

Once you have a local directory for your project you can run git init to initialise the local directory as a Git repository. Note that however this isnt connected online. To connect it to a remote repository so you can share it over the internet you have to grab the service link for the Repo, i.e for github it will be something like https://github.com/<account-name>/<repo-name>.git

So you would run git remote add origin https://github.com/<account-name>/<repo-name>.git

If you have files/directories you do not want to add to the repository you can create a .gitignore file and add these files to it and git will ignore them.

Its also helpful to create a README.md file in your repo so other people looking at the repo know what it is for.

At any point if you want to see the status of the repository enter the command git status

Once you have some files to commit (In Git terminology these are referred to as 'Dirty' files) You need to add these files to the staging environment. You can do this a couple of different ways. git add * will add every unstaged file to the staging area.

Or you can do git add <file> if you wanted to do more than 1 file at a time you can just add more files to the command separated by spaces.

Once you have files in the staging environment you need to commit these. To do this run git commit -m '<message>'

Try to make your commits have meaningful messages which explain what you're doing at each step so the project is easier to manage. Add separate commits by functional intent.

To see a log of the most recent commits on the branch do git log

Once you have some commits and want to send them to the remote repository enter the command git push <remote-name> <branch-name> in most cases this will end up being git push origin <current-branch-name> as origin is the default remote name in Github. Including the branch name is optional as by default this will push to your current branch.

Once there are other commits in the repo and you want to see the changes other developers have made. Enter the command git pull <remote> this will pull the changes from the remotes master branch into whatever local branch is currently checked out.

If you have multiple remote branches and you want to pull a specific one just do git pull <remote> <branch>

Usually its easier to do pulls in a desktop application in case you run into merge conflicts (which happens a bit when lots of people are working on the same area of the code).

When working on a project it is easier to manage the repo if you work in branches instead of only on the master branch. This way you can test out different features and approaches.

To create a new branch and start using it run git checkout -b <branch-name>

Once you are done working with a specific branch/feature and want to merge your changes, you can do this by entering the commands

git checkout <branch-to-merge-into>

git merge <branch-name>

git branch -d <branch-name>

This will switch into the receiving branch, merge the specified branch and then delete it.
