# Getting Started
## Instantiating Repositories
- Create a new repository by instantiating it through:
```shell
git init
```
- Copy an existing project by cloning the repository through:
```shell
git clone <url>
```
## Central Repos
- To instantiate a central repository a `--bare` flag is required.
- Bare repositories don't allow file editing or committing changes.
- Create a bare repo with:
```shell
git init --bare project-name.git
```
## Instantiate workflow with clone
1. Create a project in your user namespace.
- Choose to import from 'Any Repo by URL' and use <https://gitlab.com/gitlab-org/training-examples.git>.
1. Create a '`Workspace`' directory in your home directory.
1. Clone the '`training-examples`' project.
```shell
mkdir ~/workspace
cd ~/workspace
git clone git@gitlab.example.com:<username>/training-examples.git
cd training-examples
```
## Git concepts
**Untracked files**
New files that Git has not been told to track previously.
**Working area**
Files that have been modified but are not committed.
**Staging area**
Modified files that have been marked to go in the next commit.
## Committing Workflow
1. Edit '`edit_this_file.rb`' in '`training-examples`'
1. See it listed as a changed file (working area)
1. View the differences
1. Stage the file
1. Commit
1. Push the commit to the remote
1. View the Git log
```shell
# Edit `edit_this_file.rb`
git status
git diff
git add <file>
git commit -m 'My change'
git push origin master
git log
```
## Note
- `git fetch` vs `git pull`
- Pull is `git fetch` + `git merge`
