How to add pagination?

[gazpachu]

I'm struggling to add the pagination :( I've tried both plugins (gatsby-pagination and gatsby-paginate) but I see no difference. I still get the full list of posts. With gatsby-pagination I'm adding the following to gatsby-node.js:

const { createPaginationPages } = require("gatsby-pagination");

const indexPage = path.resolve("./src/pages/index.js");
const items = result.data.allMarkdownRemark.edges;

createPaginationPages({
createPage: createPage,
edges: items,
component: indexPage,
limit: 5
});

// Then the following blocks...
// Create category pages
// Create posts
// and pages.
Any idea of what I'm doing wrong? I'm still learning about Gatsby. Cheers in advance!
