-## Best practices
-
-* `pull` before `push`
-
-* Work on your <font color="red">own</font> branch (in your own fork), and **not** on `master` and **not** on `develop`
-
-* Do **not push** to `master` or `develop`, but **submit a PR/MR**
-
-* Get your code **reviewed** by your peers (submit a PR/MR!)
-
-* Submit a PR/MR **often**!
-
-* `clone` a repository, do not download the `.zip` file.
-
-
-* Do **not** combine `git` commands
-   ```bash
-   $ git commit -am "myMessage" # do not do this
-   ```
-
-* Stage only 1 file at once using
-
-   ```bash
-   $ git add myFile.txt
-   ```
-
-* Commit **only a few files** at once (after multiple separate `git add` commands)
-
-* `Push` often - avoid conflicts
-
-<br><br>
-Remember: **A `push` a day keeps conflicts away!**

-## Development scheme
-
-<br>
-Generally, in a repository, there are guidelines for contributing.
-
-<div class="fragment">
-
-<br>
-A common development scheme is dual with a:
-
-- **development** version of the code on `develop`
-- **stable** version of the code on `master`
-
-<br>
-A **version** of the code is referred to as a **branch**.
-
-<div class="fragment">
-<br><br>
-<img src="img/icon-live-demo.png" height="100px">
-
-
-<br>
-<font color="red">In the practice repository, the development branch is called `develop`!</font>
-
-<div class="fragment">
-<br>
-![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.
-
-<div class="fragment">
-<br>
-These individual code changes are called **commits**.
-
-
-For instance, the `master` and `develop` branches can be represented as a timeline:
-
-<img src="img/branch-master.png" class="branch-master" />
-
-
-## 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.
-
-<div class="fragment">
-<br>
-Checkout another branch
-```bash
-$ git checkout branchName
-```
-
-<div class="fragment">
-<br>
-You can switch to the `develop` branch with
-```bash
-$ git checkout develop
-```
-
-<div class="fragment">

-<img src="img/icon-live-demo.png" height="100px">

-<div class="fragment">
-<br>
-<font color="red">Create a new **branch**!</font>
-
-```bash
-$ git checkout -b add-2-numbers
-```
-The `-b` flag creates the branch.
-
-
-Locally, you have your own version now:
-<img src="img/branch-create.png" class="branch-create" />

-## Homework
-
-Ideally, do this exercise on a computer on which `Matlab` or `octave` **are** installed.
-
-<div class="fragment">
-<br>
-More information on how install these software are on [mathworks.com](www.mathworks.com]) or on [gnu.org/software/octave](gnu.org/software/octave)
-
-<div class="fragment">
-<br>
-Don't forget to properly configure `git` with your username and email as explained in the training slides.
-
-
-## Detailed instructions
-
-- First, fork the [https://git-r3lab.uni.lu/R3school/git.practice](https://git-r3lab.uni.lu/R3school/git.practice) repository.
-
-- Create the new branch `homework_myName`.
-
-- Implement a new function (create a new file `sqrt_myName.m` in a new folder `src/thirdCommit`) called `sqrt_myName(x)` that computes the square root of `x`.
-
-- Rename the `test.m` file in the `test/suite` directory to `test_myName.m`.
-
-- Edit the file `test.m` and change the names of the functions accordingly.
-
-
-- Before submitting the merge request, verify locally that your code is running properly.
-
-  To do so, open the MATLAB application and type `matlabroot`. This will return the path to the MATLAB application. Note or copy this path and exit MATLAB. 
-  NOTE: Do not copy the apostrophes, as they just denote the returned string.
-
-  Open the Terminal and execute the following command:
-   ```sh
-   $ matlabroot/bin/matlab -nodesktop -nosplash < test_testAll.m
-   ```
-   and verify that no error is reported.
-   NOTE: `matlabroot`in the terminal window refers to the copied path from the previous instruction.
-
-- Create a merge-request.
-
-- Assign @laurent.heirendt and your merge-request will be reviewed.
-
-<br>
-That's it!

-## What is `git`?
-
-<!-- ![](img/git_definition.png) -->
-
-`git` is a **version control system** (VCS) for tracking changes in computer files and coordinating work on those files among multiple people [1].
-
-<br><br><br>Designed and implemented in 2005 by **Linus Torvalds**
-
-![](img/linus.jpg)
-
-<div align="left"><small>[1] *https://en.wikipedia.org/wiki/Git*</small></div>
-
-
-## The inventor of `git`
-
-![](img/git_definition.png)
-<br><br>
-```
-I'm an egotistical bastard, and I name all my projects after myself.
-First Linux, now git.
-```
-Linus Torvald (2007-06-14)
-
-
-## What is the use of `git`?
-
-* No need to fully rewrite code; **reuse code** 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 code base
-
-note:
-
-Other points to mention:
-* 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.
