+# AI at the Edge
+This is the main repository of the AI at the edge project. This repository is used to store the documentation in the form of markdown files and various jupyter notebooks.
+The markdown files are used to automatically create a website using mdbook which is then deployed to gitlab pages using the CI/CD pipeline.
 
 The actual mdbook can be found in the [book](./book) directory and the accompanying jupyter notebooks can be found in the [notebooks](./notebooks) directory.
 
-The deployed documentation can be found [here](https://pse-ai-at-the-edge.h-da.io/ai-at-the-edge/).
