+## Initialize
+- Create a new projet in gitlab and take note of its url
+
+### Protecting Master Branch
+
+On the gitlab page of your project go to *Settings/Repository* in the *Protected Branches* section.
+Select the **Master** branch and set **allow to merge** to ***Master*** and **allow to push** to **No one**
+This will prevent anyone to push on the master branch, the only way to add code to the branch will be using merge requests.
+
+### Setting Development Branch
+- Retrieve the project on your computer, open a command line and execute.
+
+```
+git clone https://forge.grandlyon.com/web-et-numerique/llle.git
+```
+- Create the development branch
+
+```
+git checkout -b dev
+```
+
+- Init your project and then type any time you want to commit changes:
+
+```
+git add .
+git commit -m "Commit changes"
+git push origin dev
+```
+
+## Start Developing
+For any other development you should create a branch from the development branch.
+
+First make sure to be on the ***dev*** branch, type:
+```
+git branch
+```
+> to see your current branch
+
+### Conventional Commits
+
+The commit contains the following structural **types**:
+- fix
+- feature
+
+In our team organisation we are using IceScrum to keep track of our User Stories (US). Each US is identified by a number. In order to easily identify the commit that refers to the US, a `feature` branch name should follow this structure:
+
+- *features/<number of the User Story\>-<title_of_the_user_story\>*
+
+You can create the branch by typing:
+```
+git checkout -b features/<number of the User Story>-<title_of_the_user_story>
+```
+
+> Note that the **feature** type is the only one with a dedicated folder (features/-US).
+
+Each fix branch should be named as the following *fix-\<title_of_the_fix\>*.
+
+You can create the branch by typing:
+```
+git checkout -b fix-<title_of_the_fix>
+```
+
+**Breaking Change**
+Appends a `!` before the title of the commit to notify that a breaking change has happened. Give a solid description of the changes as well.
+
+
+**Types** other than fix and feature are allowed, for example *build*, *chore*, *ci*, *docs*, *style*, *refactor*, *perf*, *test* and others.
+
+**add tag**
+```
+git tag -a 1.0.0 -m "complementary message"
+```
