Additions, improvements, and corrections to these docs are always welcome.
The quickest way to fix typos, etc. on existing pages is to use the :guilabel:`Edit on GitHub` link in the upper right corner of the page to get to the online editor for the page on GitHub.
For more substantial work, and to add new pages, the instructions below explain how to:
- clone the repository from GitHub
- build the docs with your changes locally, and preview them in Firefox or your favourite browser instead of having to push commits to GitHub to trigger a build on readthedocs.org,
Clone the MOAD documentation repository from GitHub with:
$ git clone git@github.com:UBC-MOAD/docs.gitor copy the URI (the stuff after :command:`git clone` above) from the :guilabel:`Code` button on the repository page.
Note
The :command:`git clone` command above assumes that your are connecting to GitHub using SSH. If it fails, please follow the instructions in our :ref:`SecureRemoteAccess` docs to set up your SSH keys and :ref:`CopyYourPublicSshKeyToGitHub`.
This repository uses Pixi for package and environment management. If you don't already have Pixi installed, please follow its installation instructions to do so.
Most commands are executed using :command:`pixi run` in the :file:`docs/` directory (or a sub-directory). Dependencies will be downloaded and linked in to the working environment when you use :command:`pixi run` for the first time.
To get detailed information about the environment, the packages installed in it, Pixi tasks that are defined, etc., use :command:`pixi info`.
The MOAD documentation is written in reStructuredText and converted to HTML using Sphinx. Creating a :ref:`MOAD-DocsBuildEnvironment` as described above includes the installation of Sphinx. Building the documentation is driven by the :file:`docs/Makefile`. To do a clean build of the documentation use:
$ cd docs/
$ pixi run docsThe output looks something like:

build succeeded.
The HTML pages are in _build/html.
The HTML rendering of the docs ends up in :file:`docs/_build/html/`. You can open the :file:`index.html` file in that directory tree in your browser to preview the results of the build. To preview in Firefox from the command-line you can do:
$ firefox _build/html/index.htmlIf you have write access to the repository on GitHub, whenever you push changes to GitHub the documentation is automatically re-built and rendered at https://ubc-moad-docs.readthedocs.io/en/latest/.
Sphinx also provides a link checker utility which can be run to find broken or redirected links in the docs. Run the link checker with:
$ cd docs/
$ pixi run linkcheckThe output looks something like:
