Juju documentation is hosted on GitHub and published on jujucharms.com. Its source documents are easy to understand and edit due to the format used: standard GitHub Flavored Markdown. Conventions have been added to support doc features such as foldouts and admonishments (explained below).
Bugs for documentation issues are submitted here:
and listed here:
Here are the basic steps necessary to get a change published on the website:
- Fork the repository from github.com/juju/docs
- Make a local branch from your fork (and enter that branch)
- Edit the source documents
- Push your branch back to your fork on GitHub
- Submit a Pull Request
The source documents are located in the
src directory. From there each
language is separated into its own directory by language code. For instance,
English is under
Once submitted, a Docs team member will review your work, suggest improvements, and eventually merge it with the master branch. Don't forget to review your work before submission!
Each file has the potential to include metadata for various purposes. At the moment this is used to provide a title element, and also to implement a limited form of todo list items. Metadata is written as key : value pairs AT THE VERY TOP of the document. E.g.
Title: Contributing to Juju docs TODO: add section on metadata spellcheck everything # Title of document Well written text goes here blah blah
As you can see, the TODO metadata can have more than one item, as long as additional items are indented by at least 4 spaces directly after the previous one. The Metadata section ends immediately there is a blank line, and the normal document text can begin.
All the text is organised into sections. These are auto-generated, there is nothing extra you need to do:
# <h1> equivalent ## <h2> equivalent ### <h3> equivalent
Create a code block using the code-fencing markup of three backticks, preferably followed by the type of code:
```bash juju do something juju status ```
The most common "types" used in this documentation are:
Use a backtick to
inline commands and other literals:
Callouts are used to notify the user of additional information or warn them of potential pitfalls. This will create a notification resembling the following in the docs:
To implement this callout, use the following syntax:
!!! Note: If you want to get more information on what is actually happening, or to help resolve problems, you can add the `--show-log` switch to the juju command to get verbose output.
When a page contains a high volume of information that would otherwise require a table of contents, or similar method of quick navigation, a foldout can be used. This will create a collapsed header which, when clicked, will expand to display all the content below it.
^# Header Content can be multi-paragraphed and will be sent through the Markdown parser as long as content is continually indented under the header.
Adding a page (file) to the documentation requires the altering of
src/navigation.tpl. Doing so will insert an entry into the left navigation
pane which will allow a visitor to discover the new page.
Add the page with the following format:
<li class="sub"><a href="charms-scaling.html">Scaling Services</a></li>;
in the appropriate section. Please make sure you submit a Pull Request with a description of the new page and why it is needed!
When adding screenshots place them in
htmldocs/media. To reference them in
your page use the syntax
First you need to generate the docs from the Markdown. In the root directory first get the dependencies and make the docs:
make sysdeps make
You only need to
make sysdeps once, after that you'll have all the
dependencies you'll need to build the docs going forward.
to test the docs properly you will need to have a web server set up. See
Ubuntu and Apache. The
DocumentRoot should be the
sudo cp -R htmldocs /var/www/htmldocs
You can then point your web browser at your local machine (127.0.0.1/htmldocs) to view the files.
Alternatively, you can use Python to start a simple HTTP server on the docs
directory. Navigate to the
/htmldocs directory of the docs and run the
python -m SimpleHTTPServer
We are putting together a more comprehensive style guide, but for the moment the following are good guidelines:
- Resist being overly formal. The documentation should be like having a conversation with a knowledgeable friend
- Remember the readers are users not necessarily Juju developers
- Spell things properly! (see below)
- We use British English (en-GB). See language details, including a comparison with American English (en-US).
- If including links or examples, double-check they actually work
- We enforce 80 columns for every text file to keep it readable. Here are instructions for the vim and emacs editors.
