-iOS Apple Podcasts mini-clone
+## Project Overview
+
+Apple Podcasts allows users to listen to podcasts and interact with a 
+sophisticated UI to control their playback.
+
+This clone does not.
+
+Apple Podcasts Clone is an application built on the SwiftUI 
+framework. It focuses on the `Library` "master-detail".
+
+* ### :lipstick: The View
+  As of the 21st of May 2023, it is a <em>façade</em>: only the
+  View part of the project is serviceable.

+
+  * #### Library ("master") 💐
+
+    Users can browse a `Library` of `Podcasts` and select any podcast to inspect.
+
+  * #### Podcast ("detail") 🌻
+
+    Users can browse a `Podcast` of `Episodes`.
+
+  * #### Dark/Light themes 🌙 ☀️
+
+    This clone replicates the original dark/light themes by Apple Podcasts.
+
+    To test this, you can change your device's (or your emulator's) display
+setting to dark/light theme.
+
+  * #### Top bar ☝️
+
+    In Apple Podcasts, a stylish, slightly transparent top bar contains certain menu
+options, and displays the name of the current
+section once the user has scrolled past the corresponding header.
+
+    This clone tried to emulate that to some extent.
+
+  * #### Bottom bar 👇
+
+    In Apple Podcasts, a consistent, stylish, slightly transparent bottom bar allows
+navigation between different views, and playing songs.
+
+    This clone tried to emulate that, but only the Library is there to visit.
+

+
+* ### :necktie: The Model
+
+  A very basic Model is in place, to provide some sample data to views more easily.
+
+## Installation
+
+To run the Apple Podcasts Clone, you must use XCode -- your best bet is using a macOS machine.
+
+Once in XCode, you can look through the `Views` -- they come with their own `Previews`. Find the `MainView`, 
+and have a look around inside the preview. Sometimes, XCode is pretty neat. Sometimes...
+
+## Some known limitations and shortcomings
+
+Concerning the View part of this project:
+* in the "detail" Podcast view, instead of saying "MORE", latest episode descriptions spanning more than 3 lines are truncated with a "..."
+* throughout the app, the smart date formattings are close to the original app, but not quite as smart.
+* and many others will join this list, no doubt.
