# Podcast iOS Client
+Podcast is another app from [CUAppDev](http://cuappdev.org), a project team at Cornell University. It is a podcast client that seeks to transform the way you listen to, interact with, and share and discover podcast content.
+
+## Development
+### Installation
+We use [CocoaPods](http://cocoapods.org) for our dependency manager. This should be installed before continuing.
+
+After cloning the project, `cd` into the new directory and install dependencies with
+```
+pod install
+```
+Open the Podcast Xcode workspace, `Podcast.xcworkspace`, and enjoy!
