+## Update Content
+
+The text content of this website is stored in markdown files, to make it easier for non-it-people to edit.
+If you've never used Markdown before, [here is a cheat sheet](https://www.markdownguide.org/cheat-sheet/) with the most comman styling you might need.
+
+To update the text of this website, you have to navigate into the *src/content* folder.
+Here you will find two folders, 'pages' and 'shorts', as well as the file main-infos.md
+
+```
+/
+├── public/
+│   └── pictures
+├── src/
+│   ├── content/
+│   │   └── pages
+│   │   └── shorts
+│   │   └── main-infos.md
+```
+
+* **main-infos.md** stores what will be rendered as date (Datum), place (Ort) and price (Preis) on the landing page of this project.
+* **shorts** includes all short intro texts of the landing page
+* **pages** includes the text of all web pages. Each page has it's own document.
+
+To edit the text on the homepage, you have to edit the responding markdown file.
