-# Contributing to Rocket.Chat
-
-:+1::tada: First off, thanks for taking the time to contribute! :tada::+1:
-
-The following is a set of guidelines for contributing to Rocket.Chat and its packages, which are hosted in the [Rocket.Chat Organization](https://github.com/RocketChat) on GitHub.
-
-__Note:__ If there's a feature you'd like, there's a bug you'd like to fix, or you'd just like to get involved please raise an issue and start a conversation. We'll help as much as we can so you can get contributing - although we may not always be able to respond right away :)
-
-## Coding standards
-
-We are following / moving to [Google Java Style](https://google.github.io/styleguide/javaguide.html). There's a nice IntelliJ style file for the project in `config/quality/style-guide` for code formatting. (Note: We'll be hosting the style guide file until it's updated in the official repo)
-
-We are evaluating the Google's IntelliJ (and therefore Android Studio) [plugin](https://plugins.jetbrains.com/plugin/8527) for code formatting.
-
-We acknowledge all the code does not meet these standards but we are working to change this over time.
-
-### Syntax check
-
-Before submitting a PR you should get no errors on `checkstyle`.
-
-Just run:
-
-```
-./gradlew checkstyle
-```

.github/ISSUE_TEMPLATE.md

-Your Rocket.Chat.Android version: (make sure you are running the latest)
-<!-- Version can be found by opening the side menu and then clicking on the chevron alongside username -->
+Before writing an issue, please make sure you're talking about the native application and not the Cordova one. If you are looking to open an issue to the Cordova application, go to this URL: https://github.com/RocketChat/Rocket.Chat.Cordova.
 
-<!-- Found a bug? List all devices that reproduced it and all that doesn't -->
-Mobile device model and OS version: (e.g. "Nexus 7 - Android 6.0.1")
-<!-- Don't forget to list the steps to reproduce. Stack traces may help too :) -->
+- Your Rocket.Chat.Android app version: ####
+<!-- Make sure you are running the latest version (which can be found on the hostname screen or by opening the side menu and then clicking on the chevron alongside username -->
+- Your Rocket.Chat server version: ####
+- Device model (or emulator) you're running with: ####
+<!-- e.g. Nexus 7 - Android 6.0.1 -->
+- Steps to reproduce:
+<!-- Stack traces may help too. -->
+
+**The app isn't connecting to your server?**
+Make sure your server supports WebSocket. These are the minimum requirements for Apache 2.4 and Nginx 1.3 or greater.

+If a single device exists, install via `$ adb install /path/to/apk.apk`.

+Assuming you used Gradle like earlier, the file will be called `module_name-debug.apk` in `project_name/module_name/build/outputs/apk/`.
 
+Alternatively, you can simply run `$ ./gradlew installDebug` (`> gradlew installDebug` on Windows) to build, deploy, and debug all in a single command.
