+# Contributing
+
+The following is guide for creating a Kotatsu parsers. Thanks for taking the time to contribute!
+
+## Prerequisites
+
+Before you start, please note that the ability to use following technologies is **required**.
+
+- Basic [Android development](https://developer.android.com/)
+- [Kotlin](https://kotlinlang.org/)
+- Web scraping ([JSoup](https://jsoup.org/)) or JSON API
+
+### Tools
+
+- [Android Studio](https://developer.android.com/studio)
+- [IntelliJ IDEA](https://www.jetbrains.com/idea/) (Community edition is enough)
+- Android device (or emulator)
+
+Kotatsu parsers is not a part of Android application, but you can easily develop and test it directly inside an Android
+application project and relocate it to the library project when done.
+
+### Before you start
+
+First, take a look at `kotatsu-parsers` project structure. Each parser is a single class that
+extends `MangaParser` class and have a `MangaSourceParser` annotation.
+Also pay attention on extensions in `util` package. For example, extensions from `Jsoup` file
+should be used instead of existing JSoup functions because they have better nullability support
+and improved error messages.
+
+## Writing your parser
+
+So, you want to create a parser, that will provide access to manga from a website.
+First, you should explore a website for API availability.
+If it does not contain any documentation about
+API, [explore network requests](https://firefox-source-docs.mozilla.org/devtools-user/):
+some websites use ajax.
+
+- [Example](https://github.com/KotatsuApp/kotatsu-parsers/blob/master/src/main/kotlin/org/koitharu/kotatsu/parsers/site/DesuMeParser.kt)
+  of Json API usage.
+- [Example](https://github.com/KotatsuApp/kotatsu-parsers/blob/master/src/main/kotlin/org/koitharu/kotatsu/parsers/site/AnibelParser.kt)
+  of GraphQL API usage
+- [Example](https://github.com/KotatsuApp/kotatsu-parsers/blob/master/src/main/kotlin/org/koitharu/kotatsu/parsers/site/MangaTownParser.kt)
+  of pure HTML parsing.
+
+If website is based on some engine it is rationally to use common base class for this one (for example, Madara wordress
+theme
+and the `MadaraParser` class)
+
+### 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.
+- `getFaviconUrl` function is deprecated, but Kotatsu application before v4 still use it, so it is recommended to
+  override it too.
+- 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`
+  instead of `MangaParser`.
+
+## 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
+source is available in debug Kotatsu build.
+
+Once parser is ready you can relocate your code into `kotatsu-parsers` library project in a `site` package and create a
+Pull Request.
+
+### Testing
+
+It is recommended to run unit tests before submitting a PR.
+
+- Temporary modify the `MangaSources` annotation class: specify your parser(s) name(s) and change mode
+  to `EnumSource.Mode.INCLUDE`
+- Run the `MangaParserTest` (`gradlew :test --tests "org.koitharu.kotatsu.parsers.MangaParserTest"`)
+- Optionally, you can run the `generateTestsReport` gradle task to get a pretty readable html report from test results.
