You can either:

1. Go to https://photonstorm.github.io/phaser3-docs/index.html to read the docs online. Use the drop-down menus at the top to navigate the name spaces, classes and Game Objects lists.

2. Or, you can checkout this repository and then read the documentation by pointing your browser to the local docs/ folder. Again using the Classes and Namespaces links at the top of the page to navigate.

You can also generate new docs locally by running npm run gen and waiting (it may take up to an hour to generate the docs). See Generating the Docs Locally below for more instructions.

The TypeScript defs have been moved to the main Phaser repository.

Phaser uses the popular jsdoc, which means the documentation itself is written in the source code in the Phaser repository. In order to regenerate the docs, you'll need to clone that repository and it must be in a folder named phaser in the parent directory.

Then run npm install to install dependencies, and finally run npm run gen. The generated docs will be in a new directory called out/. Double click on out/index.html to browse the generated documentation.
