+## Set up the local development env
+1. To start the demo app with local development SDK, download following projects
+```bash
+# demo app
+$ git clone https://github.com/magiclabs/magic-ios-demo
+# ios SDK
+$ git clone https://github.com/magiclabs/magic-ios
+$ git clone https://github.com/magiclabs/magic-ios-ext
+```
+
+2. To enable the demo use the local development SDK. Navigate to `magic-ios-demo/Podfile` and edit the following lines.
+   This will make pod file install local dependencies instead of the ones distributed.
+
+```ruby 
+# Distributed Library on Cocoapods
+# pod 'MagicSDK', '~> 3.0'
+# pod 'MagicExt-OAuth', '~> 1.0'
+
+#   Local development library
+pod 'MagicSDK', :path => '../magic-ios/MagicSDK.podspec'
+pod 'MagicExt-OAuth', :path => '../magic-ios-ext/MagicExt-OAuth.podspec'
+```
+
+```bash
+$ cd /YOUR/PATH/TO/magic-ios-demo
+
+# Install dependencies
+$ pod install
+```
+
+3. Open `/YOUR/PATH/TO/magic-ios-demo/magic-ios-demo.xcworkspace` with XCode and try it out!
