Markdown & Git

What is Markdown?

Markdown is an easy way to style text on the web.
Markdown syntax consists of a plain text with a few symbols.
Markdown controls the document display through many features, such as headers, tables, links and images.

Git is a distributed version control system that creates a snapshots of a file and stores a reference to it.
Git operates locally, keeps track of file/directory changes and minimizes data loss.
Git has three states: committed (data stored in a local database), modified(file has been changed; not commited) and staged(Flagged a file’s changed version to be committed).

Cloning a file: copies all versions of all files for a project.
Clone a repository into a directory:

$ git clone https://github.com/test mydirectory
Local Repository Structure includes the following:
Working Directory: The actual files reside here.
Index: The area used for staging
Head: Points to the most recent commit

Tracked files vs. Untracked files:

Tracked files: can be modified, unmodified, or staged
Untracked files: were not in the last snapshot and do not currently reside in the staging area.
$ git status (checks git status)
git add filename (tracks single file)
$ git add * (tracks all files)
$ git commit -m “made change x,y,z” (commits and records a change)
$ git commit -a (commits all changes)
$ git push origin master (pushes changes to remote repository)
Use git remote command to view the short names, such as “origin,” of all specified remote handles.
Use git remote -v command to view all the remote URLs next to their corresponding short names.
