 # Writing Help for PowerShell Modules
@@ -33,48 +33,64 @@ A module can include the following types of Help.
 
   You can use a conceptual ("about") Help topic to describe the module and its members and to
   explain how the members can be used together to perform tasks. By default, PowerShell includes
-  over 100 of these conceptual About Help topics.
-
-  - Conceptual Help topics are text files with UTF-8 with BOM encoding.
-  - The filename must use the `about_<name>.help.txt` format, such as `about_MyModule.help.txt`.
-  - For best display results, you should limit the length of each line to 80 characters.
-  - You can use the following sample template as a starting point for writing conceptual Help
-    topics.
-
-    > [!NOTE]
-    > The `TOPIC` section header must start in the first column of the first line of the file. The
-    > section content on the second line should match the filename, without the `.help.txt` suffix.
-    > You must indent the content exactly 5 spaces. The third line must be blank. The
-    > `SHORT DESCRIPTION` section header must start in the first column of the fourth line. You must
-    > indent the content on the fifth line exactly 5 spaces. These requirements are necessary for

-    TOPIC

-    SHORT DESCRIPTION
-        A short, one-line description of the topic contents.
-
-    LONG DESCRIPTION
-        A detailed, full description of the subject or purpose of the module.

-    EXAMPLES
-        Examples of how to use the module or how the subject feature works in
-        practice.

-    KEYWORDS
-        Terms or titles on which you might expect your users to search for the
-        information in this topic.

-    SEE ALSO
-        Text-only references for further reading. Hyperlinks can't work in the
-        PowerShell console.
-    ```
-
-    Except for the first two sections, the structure of conceptual Help topics is arbitrary. The
-    remaining section titles can be whatever is appropriate for your content. By convention, you
-    should use the same capitalization, indentation, and blank line separations.

+  You can use any style and markup you want, but PowerShell sees it as plain text and there is no
+  special rendering of the text in the PowerShell console. The following suggestions ensure the best
+  display results and readability.
+
+  - Use UTF-8 with BOM encoding to ensure any special (multi-byte) characters display correctly.
+  - Underline section headers or use all uppercase letters to make they stand out. This makes the
+    content easier to scan.
+  - Limit the length of each line to 80 characters.
+  - Indent code blocks and example output to separate them from the surrounding prose.
