-## Kotatsu contribution guidelines
-
-- If you want to fix bug or implement a new feature, that already mention in the [issues](https://github.com/KotatsuApp/Kotatsu/issues), please, assign this issue to you and/or comment about it.
-- Whether you have to implement new feature, please, open an issue or discussion regarding it to ensure it will be accepted.
-- Translations have to be managed using the [Weblate](https://hosted.weblate.org/engage/kotatsu/) platform.
-- In case you want to add a new manga source, refer to the [parsers repository](https://github.com/KotatsuApp/kotatsu-parsers).
-
-Refactoring or some dev-faces improvements are also might be accepted, however please stick to the following principles:
-- Performance matters. In the case of choosing between source code beauty and performance, performance should be a priority. 
-- Please, do not modify readme and other information files (except for typos).
-- Avoid adding new dependencies unless required. APK size is important.
