 2. Run `pnpm install`. If you don't have `pnpm` installed, you can install it by running `npm install -g pnpm`.
-3. For development, run `pnpm dev`. This will start the development server and open the browser. The assets served are not optimized for production (not minimized)

+## About the solution
+
+### Caching requests
+
+Requests are persisted for 24 hours in `IndexedDB`. It was chosen over `localstorage` due to
+its asynchronous nature and better performance, as well as local storage's 5MB limit.
+
+By default, all requests are cached, since it aligns with the requirements of the test.
+However, this behaviour can be modified on per-request basis if needed.
+
+### RSS Parsing instead of iTunes API
+
+The requirements specify that the `description` field should be rendered as HTML.
+The problem with using ITunes API is that it strips all HTML tags from the description field.
+
+To circumvent this, the ITunes lookup API is only used to fetch the podcast details, from which the RSS feed URL is
+extracted.
+The RSS feed is then fetched and parsed to get the description field with HTML tags.
+
+The description is later sanitized to remove any potentially harmful tags.
+
+### Known issues
+
+- The RSS feed is fetched and parsed on the client side. This can be a performance bottleneck if the feed is large.
+- Due to RSS feed being fetch on the client side, CORS issues can arise if the feed is not properly configured. The
+	current solution
+	tries to fetch the feed directly first, and if it fails, it tries to fetch it through a proxy. The proxy in question
+	is often times very slow
+	and is not a good solution for production. A better solution would be to fetch and parse the feed on the server side.
+- RSS feed in not very well standardized, so some feeds might not be parsed correctly. In a real-world scenario, this
+	would be handled on a case-by-case basis and would require a lot of testing.
