GMCM Screen Shot

Getting Started

The GMCM is built as a Gatsby theme plugin. Your content will reside in .mdx files inside src/content that will autogenerate pages/content as you create them.

It’s simplest to use the GMCM as a localhost tool, but even if you plan to host an instance of your GMCM, it’s important to get your local environment set up first.

To get a local copy up and running, follow these simple steps.


Make sure that your terminal accepts yarn/npm and gatsby commands.

  • yarn/npm

    npm -v
    yarn -v
  • Gatsby CLI
    gatsby -v

Install these if they are not already.


  • Create the folder where your new gatsby site will live locally

    mkdir my-gmcm
    cd my-gmcm
  • Create a package.json
    yarn init -y
  • Install your packages
    yarn add react react-dom gatsby @iamgarrett/gatsby-theme-gmcm
  • Inside my-gmcm/ create a file called gatsby-config.js and add:

    module.exports = {
      plugins: ['@iamgarrett/gatsby-theme-gmcm'],
  • Run
    gatsby develop

    When the process is complete, your GMCM will be live at http://localhost:8000/


When you first run gatsby develop you’ll find your local site at http://localhost:8000/. It will be filled with example content that is housed within the plugin. To begin adding your own content, go to your project’s root directory and you’ll see that gatsby-theme-gmcm has created a src/content directory. This is where all your content will live.

There are four directories you can add to begin adding content:


In order, these will be used to contain your campaigns/adventures, any rule references you wish to document, spell documentation, monster documentation.

For more information about creating your own content, please refer to the Wiki documentation
