+  * Per Paper
+  * Per Study/Project 
+  * Per Collaborator
+* Keep <b>readme files</b> for data  
+  * Title
+  * Date of Creation/Receipt
+  * Instrument or software specific information
+  * People involved
+  * Relations between multiple files/folders 
+
+* Separate files you are actively working from the old ones  
+* Orient newcomers to the group's conventions

+
+# Data housekeeping
+<div style="position:absolute">
+
+## When working 
+  * Clarify and separate source and intermediate data

+2. Search for help 
+  * Read **FAQs**, **help pages** and the **official documentation** well before turning to Google
+  * Use stack exchange, forums and related resources carefully

+    * Make the question interesting

+# 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`, but **submit a Pull Request (PR)**
+* Get your code **reviewed** by your peers (submit a PR!)
+* Submit a PR **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.md
+   ```
+* Commit **only a few files** at once (after multiple separate `git add` commands)
+* `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 is referred to as a **branch**.
+
+<div class="fragment">
+
+<img src="slides/img/icon-live-demo.png" height="100px">
+
+
+<font color="red">In the practice 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
+
+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">
+
+Checkout another branch
+```bash
+$ git checkout <branchName>
+```
+
+<div class="fragment">
+
+You can switch to the `develop` branch with
+```bash
+$ git checkout develop
+```
+If the local branch does not exist but the remote does, it is created automatically.

+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
+```
+
+If you set a password to your key (recommended), add it to the `ssh-agent`:
+```bash
+$ eval "$(ssh-agent -s)"
+$ ssh-add -K ~/.ssh/id_rsa
+```
+
+Then, add the SSH key to Github/Gitlab.

+- 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>.

+# What is `git`?
+
+<!-- ![](slides/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].
+
+Designed and implemented in 2005 by **Linus Torvalds**
+
+<div align="center">
+<img src="slides/img/linus.jpg">
+</div>
+
+[1] *https://en.wikipedia.org/wiki/Git*
+
+
+
+# The inventor of `git`
+
+<div align="center">
+<img src="slides/img/git_definition.png">

+
+`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.
