A common development scheme is dual with a: - **development** version of the code on `develop` - **stable** version of the code on `master`
A **version** of the code is referred to as a **branch**.

In the practice repository, the development branch is called `develop`!

![bulb](img/bulb.png) Use this dual development scheme for your own repositories! ## Branches A **version** of the code (i.e., a **branch**) is made up of a sequence of code changes.

These individual code changes are called **commits**. For instance, the `master` and `develop` branches can be represented as a timeline:

## Switch between branches List all branches of the repository with ```bash $ git branch -a ``` Exit by typing `q`. The branch with the ***** is the current branch.

Checkout another branch ```bash $ git checkout branchName ```

You can switch to the `develop` branch with ```bash $ git checkout develop ```

## Create your own version Assume that you want to work on a function for adding 2 numbers.

Create a new **branch**! ```bash $ git checkout -b add-2-numbers ``` The `-b` flag creates the branch. Locally, you have your own version now:

Push your version to your fork: ```bash $ git push origin add-2-numbers ```
