+## Guidelines
+When contributing to the website's content, please try to follow the following guidelines.

+- **No upper case** except for acronyms and FR
+- [Non-English]\: Add an upper case tag for the language, for example `FR` for French
+
+Title:
+- Title should be **straight to the point and explicit**
+- [Non-English]\: Add an [emoji](https://gohugo.io/quick-reference/emojis/#country-flag) flag for the language at the end
+- [Write-Ups]\: End title with `Write-Up <CTF> <YEAR>`
+
+Files:
+- Use **lower-case, dash-separated names**
+- Filenames will become URLs, they should be **explicit, relatively short and close to article's title**
+- In case you have images: create a folder, place your article inside and name it `index.md`, an [example](https://github.com/iScsc/blog.iscsc.fr/tree/main/src/content/posts/publish-your-own-post)  
+  *NOTE: called [leaf bundle](https://gohugo.io/content-management/page-bundles/#leaf-bundles) by HUGO*
