Please read the guide Shadowing in Gatsby Themes to understand how to customize the theme! Generally speaking you will want to place your files into src/@lekoarts/gatsby-theme-graphql-playground/ to shadow/override files.

Adding content

Changing the Navigation

Create a file at src/@lekoarts/gatsby-theme-graphql-playground/data/navigation.mdx to edit the navigation.

Adding a new doc page

First, create a new entry in your navigation.mdx file. If this file doesn’t exist yet, see the step above.

You need to create a “classic” markdown list, like:

- Welcome
- Basics
  - [GraphQL Introduction](/graphql-introduction)

You’ll now see a navigation that has two sections (Welcome and Basics) of which Basics has a sub-menu.

Now, create a new file at docs/graphql-introduction.mdx. The filename has to be the same as the link you used in the navigation. Add a title to the frontmatter of the MDX file and place the GraphQL query you wish to display in the GraphiQL iFrame as the first item.

title: GraphQL Introduction

```graphql preview

Normal text can go here.

## Normal markdown too

You need to write your query with graphql preview so that the theme can pick it up. You also must place it directly after the frontmatter.

Changing the “Welcome” text

Create a file at src/@lekoarts/gatsby-theme-graphql-playground/data/index.mdx to edit the text.
