Welcome to the WordPress development repository! Please check out our contributor handbook for information about how to open bug reports, contribute patches, test, documention, or get involved in any way you can.

WordPress is a PHP/MySQL-based project. We have a basic development environment that you can quickly get up and running with a few commands. First off, you will need to download and install Docker, if you don't have it already. After that, there are a few commands to run:

Running these commands will start the development environment:

npm install
npm run build:dev
npm run env:start
npm run env:install

Additionally, npm run env:stop will stop the environment.

npm run env:cli runs the WP-CLI tool. WP-CLI has a lot of useful commands you can use to work on your WordPress site. Where the documentation mentions running wp, run npm run env:cli instead. For example, npm run env:cli help.

npm run test:php and npm run test:e2e run the PHP and E2E test suites, respectively.
