 # Extensions
 
-=== "Recommended"
+Markdown is a very small language with a kind-of reference implementation called
+[John Gruber's Markdown]. [Python Markdown] and [Python Markdown Extensions]
+are two packages that enhance the Markdown writing experience, adding useful
+syntax extensions for technical writing.

+## Configuration
+
+Extensions are configured as part of `mkdocs.yml` – the MkDocs configuration
+file. The following sections contain two example configurations to bootstrap
+your documentation project.
+
+  [overview]: #advanced-configuration
+
+### Minimal configuration
+
+The minimal configuration is a good starting point for when you're using
+Material for MkDocs for the first time. The best idea is to explore the
+[reference], and gradually add what you want to use:
+
+``` yaml
+markdown_extensions:
+
+  # Python Markdown
+  - meta
+  - toc:
+      permalink: true
+
+  # Python Markdown Extensions
+  - pymdownx.highlight
+  - pymdownx.superfences
+```
+
+  [reference]: ../../reference/abbreviations.md
+
+### Recommended configuration
+
+The recommended configuration enables all Markdown-related features of Material
+for MkDocs and is great for bootstrapping a new documentation project:
+
+``` yaml
+markdown_extensions:
+
+  # Python Markdown
+  - abbr
+  - admonition
+  - attr_list
+  - def_list
+  - footnotes
+  - meta
+  - md_in_html
+  - toc:

+      emoji_generator: !!python/name:materialx.emoji.to_svg
