Contributing

In general pull requests for small fixes/typos are welcome.

For substantial changes it's probably a good idea to let me know in advance so I can tell you if I'm interested to merge and also give you useful information.

Keep in mind I started the website all the way back in the August 2005, so there are challenges that come with maintaining the site for such a long time. It was a barebones php4 site for the first year. It was later refactored to Symfony MVC. Today Koohii still runs with Symfony 1 in the backend, but the frontend can take advantage of ViteJs, Vue 3 and Tailwind CSS.

Development

Installation is fairly simple with Docker CE. The MySQL (Mariadb) container includes a sample database with a selection of the top-voted kanji stories. See Installation and Database guides.

For any questions related to the codebase, you may be able to reach me on discord.
