 ### SuperFences

+[:octicons-tag-24: 5.0.0 – present][SuperFences support] ·
+:octicons-zap-24: Supersedes [Fenced Code Blocks]
+
+The [SuperFences] extension allows for arbitrary nesting of code and content
+blocks inside each other, including admonitions, tabs, lists and all other
+elements. Enable it via `mkdocs.yml`:
+
+``` yaml
+markdown_extensions:
+  - pymdownx.superfences
+```
+
+The following configuration options are supported:
+
+`custom_fences`{ #custom_fences }
+
+:   :octicons-milestone-24: Default: _none_ – This option allows to define a
+    handler for custom fences, e.g. to preserve the definitions of [Mermaid.js]
+    diagrams to be interpreted in the browser:
+
+    ``` yaml
+    markdown_extensions:
+      - pymdownx.superfences:
+          custom_fences:
+            - name: mermaid
+              class: mermaid
+              format: !!python/name:pymdownx.superfences.fence_code_format
+    ```
+
+    Note that this will primarily prevent syntax highlighting from being
+    applied. See the reference on [diagrams] to learn how Mermaid.js is
+    integrated with Material for MkDocs.
+
+The other configuration options of this extension are not officially supported
+by Material for MkDocs, so they may yield unexpected results. Use them at your

+[:octicons-tag-24: 5.0.0 – present][Tabbed support]

 ### Tasklist
 
+[:octicons-workflow-24: Extension][Tasklist] ·
+[:octicons-tag-24: 1.0.0 – present][Tasklist support]
+
+The [Tasklist] extension allows for the usage of [GitHub Flavored Markdown]
+inspired [task lists][Spec], following the same syntactical conventions. Enable
+it via `mkdocs.yml`:
+
+``` yaml
+markdown_extensions:

+      custom_checkbox: true
+```
+
+The following configuration options are supported:
+
+`custom_checkbox`{ #custom-checkbox }
+
+:   :octicons-milestone-24: Default: `false` · This option toggles the rendering
+    style of checkboxes, replacing native checkbox styles with beautiful icons, 
+    and is therefore _strongly recommended_:
+
+    ``` yaml
+    markdown_extensions:
+      - pymdownx.tasklist:
+          custom_checkbox: true
+    ```
+
+`clickable_checkbox`{ #clickable-checkbox }
+
+:   :octicons-milestone-24: Default: `false` · This option toggles whether
+    checkboxes are clickable. As the state is not persisted, the use of this 
+    option is _rather discouraged_ from a user experience perspective:
+
+    ``` yaml
+    markdown_extensions:
+      - pymdownx.tasklist:
+          clickable_checkbox: true
