Add the project to the footer (docusaurus.config.js):

footer: {
              style: 'dark',
              links: [{
                title: 'Projects',
                items: [{
                  label: 'OSC Website',
                  to: '/docs/website'
                },
                {
                  label: 'OSC Docs',
                  to: '/docs/osc-docs'
                }
                ]
              },

Add the project to the site index (src/pages/index.md):

## Documentation Index

* [Club Archive](/docs/club): Archive of club presentations, notes, etc.
* [OSC Website](/docs/website): User & Developer Documentation for the [OSC website](https://ufosc.org).
* [OSC Docs](/docs/osc-docs): Developer Documentation for the OSC Docs website.

I'll make sure to update the osc-docs documentation to include these instructions in the future.
