Steps to setup git repo

Setup git repo environment:

1. Setup user details

    git config --global user.name "Your name here"
    git config --global user.email "your_email@example.com"
   

2. Generate SSH key(skip to next step to reuse existing ssh key)

   a) For Mac . (Read more about SSH keys)

    ssh-keygen -t rsa -C "your_email@example.com"    b)  Copy SSH key
   
    pbcopy < ~/.ssh/id_rsa.pub For Windows,
   

   a) Either use putty.exe or open git bash and type

      ssh-keygen -t rsa
   

   then look under your_home_directory/.ssh/id_rsa.pub path and open id_rsa.pub file then copy(excluding spaces) the content(SSH key)

3. Add SSH key to account

   a) Go to https://github.com/settings/profile

   b) Open SSH key section or use https://github.com/settings/ssh

   c) Paste your key and save it

Setup local repo for new project:

1. Setup new repository

   git init

2. Create .gitignore file(for new repo) and add content from .gitignore android file, Optionally can create and add README.md for project documentation

3. Add file(s) to staging using (use git status to view the staged/unstaged changes)

    git add path/filename or add all files using
   
    git add .
   

4. Commit the previously staged changes

    git commit -m "init repo message"
   

5. Push changes to the remote repo

   a) Create a new project under github/gitlab/bitbucket account, etc and copy the SSH-link

    git remote add origin https://github.com/UserName/RepoName.git
   

   b) Pull auto-generated license or README file

   Caution: use --allow-unrelated-histories only once for new repo to pull the license, README files.

    git pull origin master --allow-unrelated-histories
   

   c) Push code

    git push origin master
   

Setup local repo using clone:

1. Clone existing project from github using

    	git clone SSH-link.git ![ssh_link](https://user-images.githubusercontent.com/11755381/75903716-fd262780-5e67-11ea-873d-bdc4377da81a.png)
   

2. Add file(s) to staging using

    git add path/filename or add all files using
   
    git add .
   

3. Commit the previously staged changes

    git commit -m "init repo message"
   

4. Push changes to the remote repo

   a) Verify the exiting remote repo link:

    git remote -v
   

   In case of no remote URL, add one using

    git remote add origin https://github.com/UserName/RepoName.git
   

   b) Push code to master branch

    git push origin master
   

   Note: To reset an existing remote URL use git remote set-url origin repo-link.

Pull Sub-module

For large repositories with submodules, it’s recommended to update them recursively as:

git submodule update --init --recursive
