+## General Formatting Guidelines
+
+Add an empty line...
+- ...after a heading
+- ...before and after an admonition or codeblock
+- ...after the admonition class for custom admonitions
+- ...after a tab opening and before a tab closing as shown in the [Tabs Section](#tabs)
+- ...before and after tables
+- ...before and after image inserts with custom properties
+
+Indent codeblocks and admonitions within numbered lists, as the numbers aren't rendered correctly otherwise.
+
+### Footnotes
+
+- This is a manually-numbered footnote reference.[^3]
+- This is an auto-numbered footnote reference.[^myref]
+
+[^myref]: This is an auto-numbered footnote definition.
+[^3]: This is a manually-numbered footnote definition.
+
+A longer footnote definition.[^mylongdef]
+
+[^mylongdef]: This is the _**footnote definition**_.
+
+    That continues for all indented lines
+
+    - even other block elements
+
+    Plus any preceding unindented lines,
+that are not separated by a blank line
+
+### Tabs
+Group tabs allow to select a tab for the whole page. As an example: If a page contains three group tabs with macOS and Windows as options and you select macOS for one section then all the sections on the page will switch to macOS.
+
+```
+::::{tabs}
+:::{group-tab} macOS
+
+text
+
+:::
+:::{group-tab} Windows
+
+text
+
+:::
+::::
+```
+
+Regular tabs are limited to the section and doesn't affect any other tabs on the page.
+
+```
+::::{tabs}
+:::{tab} Text 1
+
+text
+
+:::
+:::{tab} Text 2
+
+text
+
+:::
+```
+
+### Quotes and Code
+
+````
+```
+This is a codeblock
+```
+````
+
+`this is in line code`
+
+```
+> this is a single line Quote
+```
+
+### Links und Downloadlinks
+Add those inline into the text where needed.
+
+```
+[Formatting Cheat Sheet](Formatting_Cheat-Sheet)

+
+### Admonitions
