# Workflow
Mermaid uses a [Git Flow](https://guides.github.com/introduction/flow/)–inspired approach to branching.
Development is done in the `develop` branch.
Once development is done we create a `release/vX.X.X` branch from `develop` for testing.
Once the release happens we add a tag to the `release` branch and merge it with `master`. The live product and on-line documentation are what is in the `master` branch.
You can always check current [configuration of labelling and branch prefixes](https://github.com/mermaid-js/mermaid/blob/develop/.github/pr-labeler.yml)
- The first part is the **type** of change: a `feature`, `bug`, `chore`, `docs`
- followed by a **slash** (`/`),which helps to group like types together in many git tools
- followed by the **issue number**, e.g. `2910`
- followed by an **underscore** (`_`)
- followed by a **short description** with dashes (`-`) or underscores (`_`) instead of spaces
If your work is specific to a single diagram type, it is a good idea to put the diagram type at the start of the description. This will help us keep release notes organized by a diagram type.
> **Note**
> A new feature described in issue 2945 that adds a new arrow type called 'florbs' to state diagrams
>
> `feature/2945_state-diagram-new-arrow-florbs`
> **💡 Tip**
> A bug described in issue 1123 that causes random ugly red text in multiple diagram types
>
> `bug/1123_fix_random_ugly_red_text`
## Make changes
Source code and the documentation are located \[`packages/mermaid`]\((<https://github.com/mermaid-js/mermaid/tree/develop/packages/mermaid>) folder.
You may need to update both, depending on your task.
Read our guides on [how to contribute to code](./code.md) and [how to contribute to documentation](./documentation.md).
We make all changes via Pull Requests (PRs). Open a new one.
Right now we are not following any strict rules about naming PRs. Give it a representative title and short description. There is also a [pull_request_template](https://github.com/mermaid-js/mermaid/blob/develop/.github/pull_request_template.md) which will help you with it.
In case in its description contains a [magic comment](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue) your PR will be automatically attached to the issue:
