-# Contributing
-
-Please read in detail about how to contribute documentation and code on the [Mermaid documentation site.](https://mermaid-js.github.io/mermaid/#/development)
-
----
-
-# Mermaid contribution cheat-sheet
-
-## Requirements
-
-- [volta](https://volta.sh/) to manage node versions.
-- [Node.js](https://nodejs.org/en/). `volta install node`
-- [pnpm](https://pnpm.io/) package manager. `volta install pnpm`
-
-## Development Installation
-
-If you don't have direct access to push to mermaid repositories, make a fork first. Then clone. Or clone directly from mermaid-js:
-
-```bash
-git clone git@github.com:mermaid-js/mermaid.git
-cd mermaid
-```
-
-Install required packages:
-
-```bash
-# npx is required for first install as volta support for pnpm is not added yet.
-npx pnpm install
-pnpm test # run unit tests
-pnpm dev # starts a dev server
-```
-
-Open <http://localhost:9000> in your browser after starting the dev server.
-You can also duplicate the `example.html` file in `demos/dev`, rename it and add your own mermaid code to it.
-That will be served at <http://localhost:9000/dev/your-file-name.html>.
-
-### Docker
-
-If you are using docker and docker-compose, you have self-documented `run` bash script, which is a convenient alias for docker-compose commands:
-
-```bash
-./run install # npx pnpm install
-./run test # pnpm test
-```
-
-## Testing
-
-```bash
-# Run unit test
-pnpm test
-# Run unit test in watch mode
-pnpm test:watch
-# Run E2E test
-pnpm e2e
-# Debug E2E tests
-pnpm dev
-pnpm cypress:open # in another terminal
-```
-
-## Branch name format:
-
-```text
-   [feature | bug | chore | docs]/[issue number]_[short description using dashes ('-') or underscores ('_') instead of spaces]
-```
-
-eg: `feature/2945_state-diagram-new-arrow-florbs`, `bug/1123_fix_random_ugly_red_text`
-
-## Documentation
-
-Documentation is necessary for all non bugfix/refactoring changes.
-
-Only make changes to files that are in [`/packages/mermaid/src/docs`](packages/mermaid/src/docs)
-
-**_DO NOT CHANGE FILES IN `/docs` MANUALLY_**
-
-The `/docs` folder will be rebuilt and committed as part of a pre-commit hook.
