+# Description
+
+This document provides information on how to start developing Status App.
+
+# Getting Started
+
+To start developing start a shell for platform you are interested in.
+```
+make shell TARGET=android
+```
+This step will take a while the first time as it will download all dependencies.
+
+To build the app, your can simply run on of the following:
+```
+make release-android
+make release-ios
+```
+For more `make` targets run `make help`.
+
+# Manual Steps
+
+There are a few manual steps you might want to do in order to start contributing.
+
+## Genymotion Virtualization
+
+Optionally set up Genymotion if you don't want to use Android Virtual Device:
+
+https://www.genymotion.com
+
+## Android Development Environment
+
+You can also setup Android Development Environment + Simulator:
+
+https://facebook.github.io/react-native/docs/getting-started.html
+
+## Configure GitHub Account
+
+The optimal way of pushing to GitHubis using SSH instead of user/pass auth.
+
+It's recommented that you [add your public SSH key to your GitHub account](https://help.github.com/en/github/authenticating-to-github/adding-a-new-ssh-key-to-your-github-account).
+
+## Configure GPG Keys for signing commits
+
+In order to increase security we require all commits in `status-react` repo to be signed with a GPG key.
+
+Steps:
+1. [Generate a new GPG key](https://help.github.com/en/github/authenticating-to-github/generating-a-new-gpg-key)
+2. [Setup Git to use your GPG key](https://help.github.com/en/github/authenticating-to-github/telling-git-about-your-signing-key)
+3. [Setup Git to sign commits](https://help.github.com/en/github/authenticating-to-github/signing-commits)
+4. [Setup GitHub to validate commits](https://help.github.com/en/github/authenticating-to-github/adding-a-new-gpg-key-to-your-github-account)

+### `extra-sandbox-paths` Is a Restricted Setting
+
+When building Android on NixOS you might encounter the following error:
+```
+ignoring the user-specified setting 'extra-sandbox-paths', because it is a restricted setting and you are not a trusted user
+```
+You can mitigate this by setting the [`nix.trustedUsers`](https://nixos.org/nixos/options.html#nix.trustedusers) property.
