Tutorials are .mdx files that can be edited as explained in the markdown pages guide. However, here's a bit more information that applies specifically to the tutorials.

All .mdx files can use custom React Components that are globally available with the following tags:

• <FixedImage>{image in MDX}</FixedImage> wraps an image in a container to give it a fixed size. The style can be overriden through the style attribute.
• <HighlightBlock>{content}</HighlightBlock> wraps content in a gray block to highlight a block of content.
• <Intro>{content}</Intro> changes text styling for the introduction of pages.
• <Note>{content}</Note> a small note with smaller font-size for disclaimer of a certain content.

Each tutorial has a cover image for the index pages that needs to be declared in the header of its .mdx file as a coverImage key with the filename of the cover that must be placed in the same folder. This image should have a 3:1 ratio with a minimum width of 600px.
