# Why _git_
**Change control**
- keep track of who changed what
- revert changes easily
```bash
no more presentation_v2_final_FINAL.pptx
```
**Backup & distribute**
- store important files remotely
- easily copy and maintain on different devices
- share and edit with collaborators
```bash
no more inconsistent state
```
**Focus**
- strict version control helps you to work goal oriented
```bash
no more chaotic changes
```

# Installing _git_
Download *git* for your operating system from [https://git-scm.com/downloads](https://git-scm.com/downloads)

# Local workflow with Command Line
---
# Creating a local repository
open your `Git-Bash`
create a new directory
```bash
mkdir mywebsite
```
change into that directory
```bash
cd mywebsite
```
turn this folder into a git repository
```bash
git init
```
---
# Checking your local repository
you check the status of your repository using
```bash
git status
```
which should give you
```bash
On branch master
No commits yet
nothing to commit (create/copy files and use "git add" to track)
```
---
# Change something & commit it
In your folder `mywebsite` create a file `helloworld.html` with the content
```html
<html>
<body>
<h1>Hello World!</h1>
</body>
</html>
```
check how git sees that file
```bash
git status
```
which tells you that there are
```bash
No commits yet
Untracked files:
(use "git add <file>..." to include in what will be committed)
helloworld.html
nothing added to commit but untracked files present (use "git add" to track)
```
---
# Change something & commit it
so let's follow the advice and do
```bash
git add helloworld.html
```
and then **commit** this change
```bash
git commit -m 'add my first file'
```
you can always check everything you did with
```bash
git log
```
```bash

- revert changes
ressources:
- https://education.github.com/git-cheat-sheet-education.pdf

# Advanced topics
best-practices for commits
create branch & merge request
create issue & mention it in commit
use SSH key
fork & merge back into origin
add different remotes
---
# Best practices for commits
- single purpose
```bash
Improve best practice slide
```
- short, imperative subject line
```bash
Add best practice slide
```
- tell why, not how
```bash
Make wording on slides consistent
```
---
# Create branch & merge request
- create branch
```bash
git checkout -b new-branch
```
- push
```bash
git push --set-upstream origin new-branch
```
- merge (on gitlab)
---
# Create issue & mention it in commit
- create issue on gitlab
- commit local change with `#1` for `1` the issue number
```bash
git commit -m "resolve #1"
```
- push
- go to the issue on gitlab.com and observe
---
# Use SSH key
- create SSH key
```bash
ssh-keygen -t rsa -b 4096 -C "florian.moser3@uzh.ch" && eval $(ssh-agent -s) && ssh-add ~/.ssh/id_rsa
```
- copy `~/.ssh/id_rsa.pub`
- add the public key on gitlab.com
- clone with SSH
- try out push/pull to see it working
