 ### Appearance

+## Installation
+- Download the relevant apk from the releases
+- Install (make sure to allow install from unknown sources)
+
+### Important
+After installation, it is important to test whether alarms are working properly and reliably on your device, 
+since some devices have optimizations and settings that prevent background apps from running properly.
+
+#### Disable Battery Optimization
+- Open the app and go to to Settings (gear icon in the top-right corner) > General > Reliability
+- Select `Disable Battery Optimization`
+- A settings page will open. Find your device, select it, and select allow. If the app is not visible, 
+make sure to select 'All apps' from the dropdown
+
+#### Enable Auto Start
+- Open the app and go to to Settings (gear icon in the top-right corner) > General > Reliability
+- Select `Auto Start`. If nothing happens, the setting might not be available on your device
+- In the settings page that opens, enable Auto Start for the app. 
+
+If alarms are still not working properly, visit [https://dontkillmyapp.com/](https://dontkillmyapp.com/), 
+and try following the guide for your device.
+
+If nothing works, feel free to open an issue.
+
+## Platforms
+Currently, the app is only available for android. I don't have an apple device to develop for iOS, but feel free
+to contribute if you want iOS support. Most of the app should work fine on other platforms. The alarm and timer features
+use android-only code so that will need to be ported.
+
+## Development
+
+This app is built using flutter. All you need is to follow [this](https://docs.flutter.dev/get-started/install) 
+guide to install it, and you should be able to start developing it.
