-<h2 id="about">About The Project</h2>
+## Authoring Blog Posts
 
-Terasology’s basic engine can be extended by a huge amount (201 right now!) of modules. Keeping track of them is not the easiest task. This is why this gatsby framework provides an automated generator for a website, listing all of them. This showcase website will increase discoverability by allowing to filter and search for modules by keywords and categories.
+Terasology blog posts are authored in [GitHub markdown](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax). They typically cover relatively neutral news related to releases, recent contributions or contributor programs; however, we also value your personal project-related opinions, thoughts, and insights.
 
----
+> **⚠️ NOTE:** If you write an opinionated post about your personal experiences and views on Terasology or related topics, please add a disclaimer at the top of your blog post indicating this.
 
-<h2> Getting Started </h2>
+All blog posts are stored in the `/blog` directory with a dedicated subdirectory for each of them.
+Every blog post directory name consists of the publish date and blog post title: `<date>-<title>`, e.g. `2017-07-14-gsoc-2017-an-overview`
+Blog post directory names should not contain non-alphanumeric characters other than dashes (`-`)
 
-The module website development environment can be installed on macOS, Windows, and Linux (Debian or Ubuntu recommended). You’ll need at least 1GB of available RAM.
+> **⚠️ NOTE:** The directory name is, on a technical level, not related to the date and title in the blog post metadata. However, we ask you to comply with our convention and ensure that date and title match the blog post metadata.
 
+Blog post directories should always contain a markdown file named `index.md` which will hold the blog post content and metadata.
+Additionally, you can provide a cover image in jpg format named `cover.jpg`.
+Optionally, any images you want to include into the blog post should be in jpg format and included in the blog post directory.
+
+### Blog Post Template
+
+To allow your blog post to show up properly on the website and search results, you'll need to use the following template in your `index.md`:
+
+```
+---
+posttype: blog
+title: "My first Terasology blog!"
+cover: "./cover.jpg"
+description: "This blog is about my latest experience with Terasology"
+author: "It's me, Mario!"
+date: "2023-04-08"
+tags: ["Announcement"]
 ---

+    <div class="col-md-6"> <img src="./image-2.jpg" width="40%" /> </div>
+  </div>
+
+```
