+Also, pay attention to extensions in the `util` package. For example, extensions from the `Jsoup` file
 should be used instead of existing JSoup functions because they have better nullability support
 and improved error messages.
 
 ## Writing your parser

 ### Parser class skeleton
 
-Parser class must have exactly one primary constructor parameter of type `MangaLoaderContext` and have an
-`MangaSourceParser` annotation that provides internal name, title and language of a manga source.
-
-All functions in `MangaParser` class are documented. Pay attention to some peculiarities:
-
-- Never hardcode domain. Specify default domain in `configKeyDomain` field and obtain an actual one using `getDomain()`.
-- All ids must be unique and domain-independent. Use `generateUid` functions with relative url or some internal id which
-  is unique across the manga source.
-- `sortOrders` set should not be empty. If your source is not support sorting, specify one most relevance value.
-- If you cannot obtain direct links to pages images inside `getPages` method, it is ok to use an intermediate url
-  as `Page.url` and fetch a direct link at `getPageUrl` function.
-- You can use _asserts_ to check some optional fields. For example. `Manga.author` field is not required, but if your
-  source provide such information, add `assert(it != null)`. This will not have any effect on production but help to
-  find issues during unit testing.
-- If your source website (or it's api) uses pages for pagination instead of offset you should extend `PagedMangaParser`

 ## Development process
 
-During the development it is recommended (but not necessary) to write it directly
-in the Kotatsu android application project. You can use `core.parser.DummyParser` class as a sandbox. `Dummy` manga
