Create github account
Install git, did it with default settings, but I'm using sublime as text editor
Need R and R studio
Open Github in browser and R studio

##The first time settig up the github repository #Go to Github #Create new repository (The first time)
#Gets a github URL
#Go to R studio
#file --> new project --> Version control --> Git (add https://github.com/csapou/TestRstudioIntegration.git find it under clone or #download) --> add directory name (did it automatially) and subdirectory --> create project
#Is now connected to github. Now create an R script
#File --> New file --> R script --> add code --> save (can see it added in files)

To upload/push to github
Tools --> version control --> commit --> Select files to commit (can see the changed ones) --> Add commit message --> commit --> Push

The files should be at github (refresh)

To download/pull from github Tools --> version control --> Pull branches

Note
If you for instance change something on another computer or directly in the browser or another person changes something and trying to push (with changes) you will get an error (A good thing).
Commit your own changes (Remember to tick off the file to commit). Then have to pull latest version from github. A merge window is appearing. Perform changes in console --> save --> commit --> Have to stage all --> Add commit message --> Commit --> Push

Creating and working on branch
Make new branch
In R studio --> Make sure to branch off of typical the master see dropdown menu in environment --> Press the branch icon two squares and diamond --> Add branch name --> Can now work on branch and merge with master branch later on to have stable master branch
