-## Features
+Loop is a simple Android app that helps you create and maintain good habits,
+allowing you to achieve your long-term goals. Detailed graphs and statistics
+show you how your habits improved over time. It is completely ad-free and open
+source.
 
-* Simple and beautiful interface, following the Material Design guidelines.
-* Advanced algorithms for calculating the strength of your habits. Every repetition makes your habit stronger, and every missed day makes it weaker. A few missed days after a long streak, however, will not completely destroy your entire progress.
-* Detailed graphs and statistics, showing how did you habits improve over time. Scroll back to see the complete history of your habit.
-* Support for both daily habits and habits with more complex schedules, such as 3 times every week; one time every other week; or every other day.
-* Habit reminders at a chosen hour of the day.
-* Support for Android Wear. Reminders can be checked or dismissed from the watch.
-* Completely ad-free and open source. There are absolutely no advertisements, annoying notifications or intrusive permissions in this app, and there will never be. The complete source code is available under the GPLv3.

+## Features
+
+* **Simple, beautiful and modern interface.** Loop has a minimalistic interface
+  that is easy to use and follows the material design guidelines.
+
+* **Habit score.** In addition to showing your current streak, Loop has an
+  advanced algorithm for calculating the strength of your habits. Every
+  repetition makes your habit stronger, and every missed day makes it weaker. A
+  few missed days after a long streak, however, will not completely destroy
+  your entire progress.
+
+* **Detailed graphs and statistics.** Clearly see how your habits improved over
+  time with beautiful and detailed graphs. Scroll back to see the complete
+  history of your habits.
+
+* **Flexible schedules.** Supports both daily habits and habits with more
+  complex schedules, such as 3 times every week; one time every other week; or
+  every other day.
+
+* **Reminders.** Create an individual reminder for each habit, at a chosen hour
+  of the day. Easily check, dismiss or snooze your habit directly from the
+  notification, without opening the app.
+
+* **Optimized for smartwatches.** Reminders can be checked, snoozed or
+  dismissed directly from your Android Wear watch.
+
+* **Completely ad-free and open source.** There are absolutely no
+  advertisements, annoying notifications or intrusive permissions in this app,
+  and there will never be. The complete source code is available under the
+  GPLv3.
+
+## Installing
+
+The easiest way to install Loop is through the [Google Play Store][playstore] or [F-Droid][fdroid].
+You may also download and install the APK from the [releases page][releases];
+note, however, that the app will not be updated automatically.  To build this
+app from the source code, see [build instructions][build].
+
+## Contributing
+
+Loop is an open source project developed entirely by volunteers. If you would
+like to contribute to the project, you are very welcome. There are many ways to
+contribute, even if you are not a software developer.
+
+* **Report bugs, suggest features.** The easiest way to contribute is to simply
+  use the app and let us know if you find any problems or have any suggestions
+  to improve it. You can either use the link inside the app, or open an issue
+  at GitHub. If you would like to receive the newest versions of the app
+  earlier than everyone else, [join our open beta on Google Play][beta].
+
+* **Spread the word.** If you like the app, share it with your family, friends
+  and colleagues. You can also rate and review the app on Google Play Store, to help
+  other users find it more easily.
+
+* **Translate the app into your own language.** If you are not a native English
+  speaker, and would like to see the app translated into your own language,
+  please join our [open translation project at POEditor][poedit]. If the translation
+  is already completed, you are also very welcome to join and proofread it.
+
+* **Write some code.** If you are an Android developer, you are very welcome to
+  contribute with code. Please, see the [developer guidelines][dev-guide] for more details.
