`begin(c++)`: Resources for C++ Beginners

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

The instructions are based on this answers.ros.org thread.

You may need the latest pip, follow the official instructions.

Install bloom:
