# npx is required for first install as volta support for pnpm is not added yet.
npx pnpm install

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:

Open <http://localhost:9000> in your browser, after starting the dev server.
There is a list of demos that can be used to see and test your changes.
If you need a specific diagram, you can duplicate the `example.html` file in `/demos/dev` and add your own mermaid code to your copy.
That will be served at <http://localhost:9000/dev/your-file-name.html>.
After making code changes, the dev server will rebuild the mermaid library. You will need to reload the browser page yourself to see the changes. (PRs for auto reload are welcome!)
