To learn Grails, first of all, you will need to get started by installing Grails on your system or project.

Once all set up, we invite you to have a look at the Grails documentation, which explains all the details about the framework, such as how to use the tools that come with a Grails installation.

Grails guides, courses, books, or presentations, given about Grails at conferences, are excellent resources to learn more about Grails as well.
