 ## Style guide
 
-The documentation is written with paragraphs wrapped at 80 column lines to make
-it easier for terminal use.
-
-### Examples
-
-When writing examples, give the user hints by making them resemble what they see
-in their shell:
-
-- Indent shell examples by 4 spaces so they get rendered as code.
-- Start typed commands with `$ ` (dollar space), so that they are easily
-  differentiated from program output.
-- Program output has no prefix.
-- Comments begin with `# ` (hash space).
-- In-container shell commands begin with `$$ ` (dollar dollar space).

-### Images
-
-When you need to add images, try to make them as small as possible (e.g., as
-gifs). Usually images should go in the same directory as the `.md` file which
-references them, or in a subdirectory if one already exists.
+If you have questions about how to write for Docker's documentation (e.g.,
+questions about grammar, syntax, formatting, styling, language, or tone) please
+see the [style guide](sources/contributing/docs_style-guide.md). If something
+isn't clear in the guide, please submit a PR to help us improve it.
