Style Guide

When contributing to, please take the following style guidelines into consideration. This style guide is also found on GitHub.

Code and Command-line Styling

  • Command-line comment: All comments should have a # followed by a space and the first word should be capitalized.
# this is formatted properly :)

#this is not :( 

Command-line input and output

> turbo build -n="my image" /path/to/

[Output]	# Command-line output should be listed two spaces below.

Syntax notes

  • Always use turbo not spoon in the command line documentation.
  • All code blocks should be 'fenced' with 3 backticks (a la GFM). Inline code styles (i.e. this is a sample command: turbo run) only use 1 backtick.
  • Syntax highlighting can be specified after the top 3 backticks (not available for inline code).
  • Use inline code styles sparingly.
  • Internal links to other sections of the doc should be relative paths
    • Other doc links: /docs/[topic]/[section]
    • To the hub: /hub
    • To contact page: /contact

Adding images

  • Put the image in the same folder as the md file
  • Modify the path in the link based on the example below
  • If you need to specify image dimensions, use HTML
# GitHub location

# Markdown would be


How to Contribute

If you are not a member of the Turbo org (AKA you don't work at Turbo), fork this repo, make changes, commit, and submit a pull request. Meta files specify the section for the markdown file, and they should not be edited unless you are moving content to a different section.

Adding a Page

If adding a page to an existing section, (a) find the corresponding folder in the /doc folder and add your new .md file to it; and (b) check the file in that directory to make sure it matches the section you want to add the page to.

If adding a page and creating a new section, create a new folder under the appropriate topic. Add your new .md file and create a new file that will specify the name of the section to add. Then, add the new section you are creating to the meta.yaml file, rearranging the ordering of the other sections as you see fit.

Creating a New Topic

To add a new topic to the top navbar, first create a new folder in the /doc directory corresponding to your topic. Then, edit the meta.yaml file, adding your new topic and rearranging the topic ordering as you see fit. Follow existing patterns when editing this file.

Populate your new directory in the /doc folder with subdirectories and new markdown files. Make sure that any subdirectory containing documentation has a file.


This section outlines the structure of the Turbo doc repo and how it is assembled.


The overall structure of the page is dictated by the meta.yaml file, located at /doc/meta.yaml. Each document in the yaml file specifies a topic that will appear in the top navbar of the docs page. A topic must have the following three properties:

  1. A display_name. This is the actual wording that will appear in the top nav bar
  2. An ordering. This is the order, left-to-right, that the topic will appear in the nav bar, relative to all other topics.
  3. A list of sections. This list is used to populate the topic's dropdown.

Each topic has an attribute called sections. Each section must in turn have the following attributes:

  1. A display_name. This will be the text that appears for that section in the containing topic's dropdown. The display_name is also used as the basis for forming that section's id on docs.html. The id for a section is the display_name with spaces translated to '+' and with all special characters encoded (except '?', which is trimmed out).
  2. An ordering. This is the top-to-bottom ordering, relative to other sections in the topic, that this section will appear in the topic dropdown.
  3. A list of pages. This should always be an empty list in the meta.yaml file.
  4. A list of subsections. These will be a list of subtopics for the specified section. Subsections have the same attributes as sections.

Each subdirectory of the /doc folder must be populated with a file. This file tells the build script which section to add that folder's pages to (appended to the pages list attribute of a section). The does not apply to subdirectories. A file must have the following structure:

topic: <display_name of topic>
section: <display_name of section>

If a file specifies a section that is not listed in topic specified, the script will raise a NoSuchSectionError.

If the folder has doc in it and there is no file, a NoMetaFileError will be raised.
