To specify your own path to the config, use the CLI argument `-c` or `--config`. +* `listen` -- the address and port on which SkunkyArt will listen +* `base-path` -- the path to the instance. Example: "`base-path`:"/art/" -> https://skunky.ebloid.ru/art/ +* `cache` -- caching system; default is off. +* * `path` -- the path to the cache +* * `lifetime` -- cache file lifetime; measured in Unix milliseconds. +* * `max-size` -- maximum file size in bytes. +* `dirs-to-memory` -- this setting determines which directories will be copied to RAM when SkunkyArt is started. Required +* `download-proxy` -- proxy address for downloading files. +## Examples of reverse proxies +Nginx: +```apache +server { + listen 443 ssl; + server_name skunky.example.com; + + location ((BASE URL)) { # if you have a separate subdomain for the frontend, insert '/' instead of '((BASE URL))'. + proxy_set_header Scheme $scheme; + proxy_http_version 1.1; + proxy_pass http://((IP)):((PORT)); + } +} +``` +## How do I add my instance to the list? +To do this, you must either make a PR by adding your instance to the `instances.json` file, or report it to the room in Matrix. I don't think it needs any description. However, be aware, this list has a couple rules: +1. the instance must not use Cloudflare. +2. If your instance has modified source code, you need to publish it to any free platform. For example, Github and Gitlab are not. +## Acknowledgements +* [Лис⚛](https://go.kde.org/matrix/#/@fox:matrix.org) -- helped me understand Go and gave me a lot of useful advice on this language. + +# RU 🇷🇺 +## Описание +SkunkyArt 🦨 -- альтернативный фронтенд к DeviantArt, который будет работать без проблем даже на довольно старом оборудовании, за счёт отсутствия JavaScript. +## Конфиг +Пример конфига находится в файле `config.example.json`.

Думаю, он не нуждается в описании. Однако учтите, у этого списка есть пара правил: +1. Инстанс не должен использовать Cloudflare. +2.
