+DocPicker
+======================
+
+DocPicker accompanies to the [Introduction to the Document Picker](http://developer.xamarin.com/guides/ios/platform_features/introduction_to_the_document_picker/) guide in the developer portal.
+
+## Setting up sample
+
+To run this sample you need to have an app ID with CloudKit
+entitlements enabled and provisioning profile linked to it.  
+
+Follow the steps in the [Introduction to the Document Picker](http://developer.xamarin.com/guides/ios/platform_features/introduction_to_the_document_picker/#Enabling_iCloud_in_Xamarin) guide to set up your provisioning profile. These are also listed below.
+
+If you don't have one please go to
+https://developer.apple.com/membercenter/index.action, select
+"Certificates, Identifiers & Profiles" and use the following
+instructions.
+
+First of all, you should create an app ID.  To do that, select "App
+ID's" in "Identifiers" section and then press add button at top-right
+corner of the screen.
+
+* Enter app ID description, e.g.: "CloudKit Atlas sample"
+* Select "Explicit App ID" in App ID Suffix and enter bundle ID, e.g.:
+  com.yourcompanyname.CloudKitAtlas
+* In App Services services section select iCloud, Include CloudKit support
+* Then press Continue button and check that everything is alright
+* Press Submit
+
+On the second step we should create provisioning profile linked to
+newly created app ID. Select "All" in "Provisioning Profiles" section
+and then press add button at top-right corner of the screen.
+
+* Select "iOS App Development" and press Continue button
+* Select newly created app ID in drop down list and press Continue button
+* Then select your team members and press Continue button
+* Select your devices and press Continue button
+* Enter profile name, e.g.: "CloudKit Atlas Development"
+* Download provisioning profile and then double click it to install
+
+Finally, open sample in Xamarin Studio and open project settings.
+
+* Set bundle identifier in "iOS Application" section and select
+  provisioning profile created earlier in "iOS Bundle Signing".
+* Close project's options and select Entitlements.plist in project
+  explorer then nable iCloud and check the CloudKit option.
+* Make sure you are signed into your iCloud account in the simulator
+  or device before running the app.
