Welcome to the WordPress development repository! Please check out the contributor handbook for information about how to open bug reports, contribute patches, test changes, write documentation, or get involved in any way you can.
You will need a basic understanding of how to use the command line on your computer. This will allow you to set up the local development environment, to start it and stop it when necessary, and to run the tests.
brew install node
choco install nodejs
apt install nodejs npm
If you are not using a package manager, see the Node.js download page for installers and binaries.
You will also need Docker installed and running on your computer. Docker is the virtualization software that powers the local development environment. Docker can be installed just like any other regular application.
Development Environment Commands
Ensure Docker is running before using these commands.

Your WordPress site will accessible at http://localhost:8889. You can see or change configurations in the
.env file located at the root of the project directory.

To restart the development environment
You may want to restart the environment if you've made changes to the configuration in the
.env files. Restart the environment with:
npm run env:restart
To stop the development environment
You can stop the environment when you're not using it to preserve your computer's power and resources:
npm run env:stop
