Let's build Markdown pages with Gatsby.

Gatsby Markdown Plugin

Using the plugin gatsby-transformer-remark, add to gatsby-config.js

{
    resolve: `gatsby-transformer-remark`,
    options: {
        excerpt_separator: `<!-- end -->`,
        plugins: [`gatsby-plugin-catch-links`],
    },
},

Use the excerpt_separator in your markdown files to notify the parser of the end of your excerpt.

Gatsby needs to know where to find the markdown files

{
    resolve: `gatsby-source-filesystem`,
    options: {
        name: `markdown-content`,
        path: `${__dirname}/src/markdown/content`,
    },
},
{
    resolve: `gatsby-source-filesystem`,
    options: {
        name: `markdown-blogs`,
        path: `${__dirname}/src/markdown/blogs`,
    },
},

My markdown files have different purposes and need to be handled differently in gatsby-node.js

gatsby-node.js generates the pages of the website.
