The [repository](https://github.com/raman-babich/public-private-fork-poc) for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented [here](https://help.github.com/articles/duplicating-a-repository/).

For this assignment the commands are:

 1. Create a bare clone of the repository.
    (This is temporary and will be removed so just do it wherever.)
    ```bash
    git clone --bare git@github.com:raman-babich/public-private-fork-poc.git
    ```

 2. [Create a new private repository on Github](https://help.github.com/articles/creating-a-new-repository/) and name it `private-private-fork-poc`.
    > If you are unable to create a private repo, you can request unlimited private repos as a student by getting
    > the [student pack](https://education.github.com/pack) from Github.

 3. Mirror-push your bare clone to your new `private-private-fork-poc` repository.
    > Replace `<your_username>` with your actual Github username in the url below.
    
    ```bash
    cd public-private-fork-poc.git
    git push --mirror git@github.com:<your_username>/private-private-fork-poc.git
    ```

 4. Remove the temporary local repository you created in step 1.
    ```bash
    cd ..
    rm -rf public-private-fork-poc.git
    ```
    
 5. You can now clone your `private-private-fork-poc` repository on your machine (in my case in the `code` folder).
    ```bash
    cd ~/code
    git clone git@github.com:<your_username>/private-private-fork-poc.git
    ```
   
 6. Add the original repo as remote.
    ```bash
    git remote add upstream git@github.com:raman-babich/public-private-fork-poc.git
    ```
    You can list all your remotes with `git remote -v`. You should see:
    ```
    origin	git@github.com:<your_username>/private-private-fork-poc.git (fetch)
    origin	git@github.com:<your_username>/private-private-fork-poc.git (push)
    upstream	git@github.com:raman-babich/public-private-fork-poc.git (fetch)
    upstream	git@github.com:raman-babich/public-private-fork-poc.git (push)
    ```
    Update remotes:
    ```bash
    git remote update
    ```
    Create `upstream-master` branch and configure upstream to `upstream/master`.
    Configure upstreams for branches:
    ```bash
    git checkout -b upstream-master upstream/master
    ```
    `upstream-master` will be your local convenient clone of the `git@github.com:raman-babich/public-private-fork-poc.git` `master` branch. You can simple `git pull` and `git push` to pull or push from `git@github.com:raman-babich/public-private-fork-poc.git` `master` branch.
 7. If you have new commits on your public repo and you want to sync up them with private one.
    ```bash
    git checkout upstream-master
    git pull
    git checkout master
    git merge upstream-master
    ```
    Or
    ```bash
    git checkout master
    git pull upstream master
    ```
    And resolve conflicts if they appear.
 8. If move some commits from your private fork to public repo. (Just cherry pick them)
    ```bash
    git checkout upstream-master
    git pull
    git cherry-pick <masterCommitSha>
    git push
    ```
    Resolve conflicts if they appear.
