-## Serverless Workflow Specification Website [![Netlify Status](https://api.netlify.com/api/v1/badges/3e2428ca-8d7f-426f-91cf-de4f68631600/deploy-status)](https://app.netlify.com/sites/serverlessworkflow/deploys)  [![Gitpod ready-to-code](https://img.shields.io/badge/Gitpod-ready--to--code-blue?logo=gitpod)](https://gitpod.io/#https://github.com/serverlessworkflow/serverlessworkflow.github.io)
+# Serverless Workflow Website Repository
 
-This repository includes sources for the Serverless Workflow Specification Website:
-* [serverlessworkflow.org](http://serverlessworkflow.org)
-* [serverlessworkflow.io](http://serverlessworkflow.io)
+This repository hosts the website for the [Serveless Workflow Specification](https://github.com/serverlessworkflow/specification) project at [https://serverlessworkflow.io](https://serverlessworkflow.io).
+
+## Contributing to the website
+
+The website uses [Hugo](https://gohugo.io/) and [Docsy](https://www.docsy.dev/). You can find more information about how to get started with this stack [here](https://www.docsy.dev/docs/get-started/).
+
+To contribute to the website you don't need to have in-deth web design knowledge:
+
+- To add a new content [follow this guide](https://www.docsy.dev/docs/adding-content/content/)
+- To publish a blog post just add a new Markdown page to the [`blog`](blog) directory. You can always use the blog posts in this repository as a reference. [Here's a good example](https://github.com/google/docsy-example/blob/main/content/en/blog/releases/in-depth-monoliths-detailed-spec.md).
+- For more complex changes to the website, look at the [Docsy](https://github.com/google/docsy) repository as a reference. Sometimes you might need to change the [default templates](https://github.com/google/docsy/tree/main/layouts) to accomodate custom changes.
