How to add the remote github origin to Rstudio package project

Create new project (New Directory > R Package > name the package) and click also “Create git repository”
This will build the package skeleton in appropriate subfolders (man, R)
Now you need to create remote origin: open shell, and type:
```
git remote add origin https://github.com/USERNAME/PACKAGE.git
```
(this will add the origin to the RStudio options - Tools > Project options > Git/SVN)
Choose what to commit (e.g. everything:)
```
git add .
```
Make the initial commit:
```
git commit -m "initial commit"
```
Establish this repository in GitHub
Push the commit:
```
git push -u origin master
```
