+# Introduction
+
+### Hey you !
+
+Thank you for wanting to help. Even the smallest things can help this project become better.
+
+Please read the guidelines before contributing, and follow them (or try to) when contributing.
+
+### What you can do to help.
+
+There are many ways to contribute to this project, you could [translate the app](https://crowdin.com/project/readerforselfoss), report bugs, request missing features, suggest enhancements and changes to existing ones. You also can improve the README with useful tips that could help the other users.
+
+You can fork the repository, and [help me solve some issues](https://github.com/aminecmi/ReaderforSelfoss/issues?q=is%3Aissue+is%3Aopen+label%3A%22Up+For+Grabs%22) or [develop new things](https://github.com/aminecmi/ReaderforSelfoss/issues)
+
+### What I can't help you with.
+
+Please, don't use the issue tracker for anything related to [Selfoss itself](https://github.com/SSilence/selfoss). The app calls the api provided by Selfoss, and can't help with solving issues with your Selfoss instance.
+
+Always check if the web version of your instance is working.
+
+# Some rules
+### Bug reports/Feature request
+
+* Always search before reporting an issue or asking for a feature to avoid duplicates.
+* Include your unique user id. It's displayed on the debug settings page. (You can tap it, it'll be copied to your clipboard)
+* Include every other useful details (app version, phone model, Android version and screenshots when possible).
+* Avoid bumping non-fatal issues, or feature requests. I'll try to fix them as soon as possible, and try to prioritize the requests. (You may wan to use the [reactions](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments) for that)
+
+### Pull requests
+
+* Don't create a PR for translations. See [here](https://github.com/aminecmi/ReaderforSelfoss/pull/170#issuecomment-355715654) for an explanation why.
+* Please ask before starting to work on an issue. I may be working on it, or someone else could be doing so.
+* Each pull request should implement **ONE** feature or bugfix. Keep in mind that you can submit as many PR as you want.
+* Your code must be simple and clear enough to avoid using comments to explain what it does.
+* Follow the used coding style [the android koding style](https://android.github.io/kotlin-guides/style.html) ([some idoms for reference](http://kotlinlang.org/docs/reference/idioms.html)) with more to come.
+* Try as much as possible to write a test for your feature, and if you do so, run it, and make it work.
+* Always check your changes and discard the ones that are irrelevant to your feature or bugfix.
+* Have meaningful commit messages.
+* Always reference the issue you are working on in your PR description.
+* Be willing to accept criticism on your PRs (as I am on mine).
+* Remember that PR review can take time.
+
+
+# Build the project
+
+You can directly import this project into IntellIJ/Android Studio.
+
+You'll have to:
+
+- Define some parameters either in `~/.gradle/gradle.properties` or as gradle parameters (see the examples)
+
+    - appLoginUrl, appLoginUsername and appLoginPassword: url, username and password of a selfoss instance. **These are only used for tests. They can be empty if you don't test API calls.**
+
+### Examples:
+#### Inside ~/.gradle/gradle.properties
+
+```
+appLoginUrl="URL" # It can be empty.
+appLoginUsername="LOGIN" # It can be empty.
+appLoginPassword="PASS" # It can be empty.
+```
+
+#### As gradle parameters
+
+```
+./gradlew .... -P appLoginUrl="URL" -P appLoginUsername="LOGIN" -P appLoginPassword="PASS"
+```
