## Branch model

TL;DR:
> **create a fork from iTop main repository,  
> create a branch based on either release branch if present, or develop otherwise**

We are using the [GitFlow](https://nvie.com/posts/a-successful-git-branching-model/) branch model. That means we have in our repo those
main branches:

- develop: ongoing development version
- release/\*: if present, that means we are working on a beta version
- master: previous stable version

For example, if no beta version is currently ongoing we could have:

- develop containing future 2.8.0 version
- master containing 2.7.x maintenance version

In this example, when 2.8.0-beta is shipped that will become:

- develop: future 2.9.0 version
- release/2.8: 2.8.0-beta
- master: 2.7.x maintenance version

And when 2.8.0 final will be out:

- develop: future 2.9.0 version
- master: 2.8.x maintenance version
- support/2.7 : 2.7.x maintenance version


## Coding

### PHP styleguide

### Git Commit Messages

* Describe the functional change instead of the technical modifications
* Use the present tense ("Add feature" not "Added feature")

    * 🔥 `:fire:` when removing code or files
    * 💚 `:green_heart:` when fixing the CI build
