-`SECRET_KEY` must use your own, back it up well somewhere
-`SITE_INFO` change by you need
-`REDIRECT_URIS` this should be `SITE_INFO["site_url"] + "/account/login/oauth"` . It used to be multiple urls separated by `\n` , but now it must be only one url, bc not all Fediverse software support >1 urls very well. Also note changing this later may invalidate app token granted previously
-`SEARCH_BACKEND` should be ~~either~~`TYPESENSE`~~or `MEILISEARCH`~~ so that search and index can function. `None` will use default database search, which is for development only and may gets deprecated soon.
-`MEILISEARCH` support is removed due to lack of usage, feel free to PR if you want to
