-# Project Prisma App
-
-This is a repository for an Ionic app for [Project Prisma](http://www.frederikvincx.com/project-prisma-helping-people-with-dementia). The Ionic app works on both Android and iOS devices.
-
-The app communicates with a [RESTful API](https://github.com/oSoc17/prisma-backend).
-
-## About
-
-Project Prisma is part of [open Summer of Code 2017](http://2017.summerofcode.be/). A student team coached by Frederik Vincx [(@fritsbits)](https://github.com/fritsbits) is working on it now:
-- Michiel Leyman [(@MichielLeyman)](https://github.com/MichielLeyman) - backend & project management
-- Simon Westerlinck [(@siimonco)](https://github.com/siimonco) - backend
-- Jean-Pacifique Mboynincungu [(@oxnoctisxo)](https://github.com/oxnoctisxo) - frontend & system analysis
-- Thor Galle ([@th0rgall)](https://github.com/th0rgall) - frontend & user testing
-
-## Installation

+
+Prisma is an app that strengthens the relationship between people with memory loss and the people close to them. It does this by providing a living, collaborative digital photo album that can be populated with content of interest to these people.
+
+This repository hosts the frontend of the project: a mobile app based on the [Ionic framework](https://ionicframework.com/). The app communicates with a [RESTful API](https://github.com/Prisma/prisma-backend) to gather and save data.

+## History
+
+Project Prisma was part of [Open Knowledge Belgium](https://www.openknowledge.be/)'s [open Summer of Code 2017](http://2017.summerofcode.be/). A student team coached by Frederik Vincx [(@fritsbits)](https://github.com/fritsbits) worked on it in July 2017:
+- Michiel Leyman [(@MichielLeyman)](https://github.com/MichielLeyman) - backend & project management
+- Simon Westerlinck [(@siimonco)](https://github.com/siimonco) - backend & database modelling
+- Jean-Pacifique Mboynincungu [(@oxnoctisxo)](https://github.com/oxnoctisxo) - frontend system analysis
+- Thor Galle [(@th0rgall)](https://github.com/th0rgall) - frontend & product owner
+
+The app was conceived in a one-month collaborative design project in a care home in Zonhoven, Belgium, in January 2017. Together with personel and dementia design researchers the team honed in on a static prototype that was later refined during the Open Summer of Code. More info about it in [this blog post](http://www.frederikvincx.com/project-prisma-helping-people-with-dementia/).
+
+## Installation
+
+We aim to have the app available for download in the Play Store soon. However, if you want to try it out right now, there are several options.
+
+### 1. Prepackaged application
+
+The easiest way is by downloading a binary release package and installing it on your device:
+
+1. Download the latest Android package (.apk) from our [releases page](https://github.com/Prisma/prisma-frontend/releases).
+2. In your Android device, look for the setting "Unknown sources" (probably in your security settings), and check/allow it.
+3. Transfer the .apk file to your Android device. Now you can install Prisma from there using your file manager of choice.
+
+### 2. Using the development tools 
+
+If you have some command line & git experience, this is a more flexible way to get the latest version of the app.
+
+#### Setting up the development environment
+
+1. Clone the repository
+
+   ```bash 
+   git clone https://github.com/Prisma/prisma-frontend.git
+   ```
+
+2. Install [npm](https://www.npmjs.com/) if you haven't already.
+
+3. On the command line inside the repository, install Cordova & Ionic. Then install the dependencies.
+
+   ```bash
+   npm install -g cordova ionic
+   npm install
+   ```
+
+
+Now you can run the app in various ways:
+
+#### a) Ionic web server
+
+Ionic comes with a local web server for development purposes that serves the application & recompiles on file changes. 
+
+Because cordova.js is not included, phone-specific features will not work. Notably, adding content doesn't work.
+
+```bash
+ionic serve
+```
+
+#### b) Cordova Browser build
+
+Comparable to the previous method, but here a browser implementation of Cordova is included. Note that this implementation is not fully supported yet. 
+
+```bash
+ionic cordova platform add browser
+ionic cordova run browser # starts a webserver
+```
+
+#### c) Android build
+
+In order to build for Android, you'll need to have the [Java JDK](http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html), [Android Studio](https://developer.android.com/studio/index.html) and the appropriate [Android SDK tools](https://developer.android.com/studio/intro/update.html) for your device installed. 
+
+Also, make sure that the necessary folders are in your `PATH` so that the build executables can be found.
+
+On a Linux system with a default Android Studio install the following lines need to be added to the terminal configuration file. It might be different on your system.
+
+```bash
+PATH=PATH:$HOME/Android/Sdk/platform-tools:$HOME/Android/Sdk/tools
+ANDROID_HOME=$HOME/Android/Sdk
+```
+
+Now you can build & transfer the project to your device using the Cordova `run` command.
+
+```bash
+ionic cordova platform add android
+ionic cordova run android
+```
+
