+# Best practices
+
+* Fetch the upstream before creating a new branch.
+* Work on your <font color="red">own</font> branch (in your own fork), and **not** on `master` and **not** on `develop`
+* Get your code **reviewed** by your peers (submit a PR!)
+* Submit a PR **often**!
+* `Push` often - avoid conflicts
+
+Remember: **A `push` a day keeps conflicts away!**

+# Development scheme
+
+
+Generally, in a repository, there are guidelines for contributing.
+
+<div class="fragment">
+
+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/text is referred to as a **branch**.
+
+<div class="fragment">
+
+<font color="red">In the `howto-cards-internal` repository, the development branch is called `develop`!</font>
+
+<div class="fragment">
+
+![bulb](slides/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.
+
+<div class="fragment">
+
+These individual code changes are called **commits**.
+
+
+For instance, the `master` and `develop` branches can be represented as a timeline:
+<img src="slides/img/branch-master.png" class="branch-master" height="500em"/>

+
+
+# Switch between branches
+
+<img src="slides/img/icon-live-demo.png" height="100px">
+
+
+
+# Create your own version
+
+Assume that you want to work on a file:
+
+<div class="fragment">
+
+<font color="red">Create a new **branch** and start editing!</font>

+# How to configure `git`?
+
+```bash
+$ git config --global user.name "Firstname Lastname"
+$ git config --global user.email "first.last@uni.lu"
+```
+
+Test whether your username and email have been registered
+
+```bash
+$ git config --list
+```
+
+This should list the configuration with `user.name` and `user.email`.
+
+
+
+
+# What is an SSH key?
+
+An SSH key is a secure access credential.
+
+**Principle**: <br><br>
+Communicate **securely** with Github/Gitlab **without** entering the username/password.
+
+
+
+# How do I get and set my SSH key?
+
+Check if you already have an SSH key:
+
+```bash
+$ ls -al ~/.ssh
+```
+
+If there are 2 files named `id_rsa`, you have an SSH key.
+
+If you don’t have yet an SSH key, you have to generate one:
+```bash
+$ ssh-keygen -t rsa # -b 4096
+```
+
+Then, add the SSH key to your profile on git-r3lab.
+
+On Windows, please unmount `P:\` (your personal atlas folder) first.

+
+- In general, when contributing to a repository, you only have **read** access.
+
+- In other words, you can only **pull** (unless it is your own repository or access has been granted).
+
+- In general, you **cannot write** changes. In other words, you do not have **push** access.
+
+- You have to work on your **own copy**.
+
+- In other words, you have to work on your own <font color="red">**fork**</font>.
+
+<br>
+<h2>How to get a fork?</h1>
+
+Browse to the original repository and click on the button `Fork`:
+
+![Fork the repo](https://help.github.com/assets/images/help/repository/fork_button.jpg)
+
+
+
+
+# How to update my fork?
+
+As you have your own fork, it will not automatically be updated once the original repository is updated.
+
+![bulb](slides/img/bulb.png) You have to update it yourself!

+# What is `git`? (i)

+# What is the use of `git`?
+
+* `git` can be used for code or text documents, such as markdown language
+
+* No need to fully rewrite code/text; **reuse code/text** and **save time**
+
+* Keep the changes you made over time (**history**)
+
+* Allows you to **backtrack** (if necessary) and undo unwanted changes
+
+* Easily **add contributions** of your collaborators to the main repository
+
+<br>
+Other points:
+
+- `git` shall not be considered as a nuisance, but as a tool that should help to track and trace the code.
+
+- `git` is not to track performance. Not using it shows exactly the opposite.
