Git and github introduction

This repository gives a short introduction for Fontys University of Applied Sciences in Venlo Software Engineering and Business Informatics students regarding usage of Git and Github.

What is Git?

• DVCS – Distributed Version Control System
• Like a “more advanced” SVN (Subversion)
• Most used VCS in the world (>70%)
• Used often in open source projects

What is Github?

• Git hosting repository - see github.com
• Besides hosting additional features
• Own workflow (pull requests)
• There are more hosters: bitbucket, gitlab ...

More information: github guide

Markdown

Markdown is the language for documenting and communication. Comparable to Asciidoc.

How do write markdown:

Markdown Syntax

Headers

# This is an <h1> tag
## This is an <h2> tag
###### This is an <h6> tag

This is an <h1> tag

This is an <h2> tag

This is an <h6> tag

Emphasis (Bold, Italic)

*This text is italic*
_This is also italic_

This text is italic This is also italic

**This text is bold**
__This is also bold__

This text is bold This is also bold

_You **can** also combine them_

Lists

Unordered

* Item 1
* Item 2
  * Item 2a
  * Item 2b

• Item 1
• Item 2
  • Item 2a
  • Item 2b

Ordered

You do not need to manually number your ordered list. Subsequent items in the list will be automatically numbered if you use - instead of numbers.

1. Item 1
- Item 2
- Item 3
   1. Item 3a
   - Item 3b

1. Item 1

• Item 2
• Item 3
  1. Item 3a
  • Item 3b

Combined

1. Item 1
- Item 2
   - Sub-item
   - Sub-item

1. Item 1

• Item 2
  • Sub-item
  • Sub-item

Task Lists

- [x] first, choose an ordered or unordered list style, then add checkboxes
- [x] completed item
- [ ] incomplete item

• first, choose an ordered or unordered list style, then add checkboxes
• completed item
• incomplete item

Tables

You can create tables by assembling a list of words and dividing them with hyphens - (for the first row), and then separating each column with a pipe |:

Column 1 Header | Column 2 Header
------------ | -------------
Content from cell 1 | Content from cell 2
Content in the first column | Content in the second column

First Header	Second Header
Content from cell 1	Content from cell 2
Content in the first column	Content in the second column

Strikethrough

Images

Image syntax allows for alternative text. The format is ![alt text](URL). The URL can be a relative project path or an external website URL.

![Org Logo](logo_square.png)
![Org Logo](https://raw.githubusercontent.com/wendikristine/documentation-template/master/logo_square.png)

Links

Links are created automatically in most cases (and always on Github). Or, you can specify a link with alternative text.

http://github.com - automatic!

Code

I think you should use an
`<addr>` element here instead.

Markdown supports language-specific syntax highlighting.

function fancyAlert(arg) {
  if(arg) {
    $.facebox({div:'#foo'})
  }
}

function fancyAlert(arg) {
  if(arg) {
    $.facebox({div:'#foo'})
  }
}

You can also simply indent your code by four spaces:

function fancyAlert(arg) {
  if(arg) {
    $.facebox({div:'#foo'})
  }
}

Horizontal Rule

Emoji

GitHub supports emoji! ✨ 🐫 💥

To see a list of every image we support, check out the Emoji Cheat Sheet.

See Mastering Markdown for more information about Markdown.

Git tools

There are a bunch of (GUI) Tools out there for interacting with Git. Ask Google to find out what your preference is.

In the first weeks the github.com interface here is enough.

• Git CLI (Console in Linux, Windows, Mac)
• Github Desktop
• GitKraken
• Atlassian SourceTree
• Tortoisegit (Windows only)
