To post your podcast on Apple Podcasts, you need to follow these steps:

1. **Create Your Podcast**: Before you can post anything, you need to have a podcast ready. This includes having at least one episode fully produced and ready to go, as well as a title, description, and cover art for your podcast.

2. **Host Your Podcast**: Apple Podcasts does not actually host podcasts. Instead, you'll need to upload your podcast to a hosting platform. There are many to choose from, including Libsyn, Podbean, and Anchor.

3. **Get Your RSS Feed**: Once your podcast is hosted, your hosting platform will provide you with an RSS feed. This is a URL that starts with "http://" or "https://". This RSS feed is what you'll submit to Apple Podcasts.

4. **Submit Your Podcast to Apple Podcasts**: To do this, you'll need an Apple ID. If you don't already have one, you can create one for free. Then, go to Podcasts Connect (podcastsconnect.apple.com), log in with your Apple ID, and agree to the terms of service. Click the "+" button in the top left corner, then enter your RSS feed into the provided field. Click "Validate," and if everything is set up correctly, you should see a preview of your podcast.

5. **Submit For Review**: If everything looks good, click "Submit." Apple will then review your podcast, which can take up to a few days. Once it's approved, your podcast will be available on Apple Podcasts.

Remember to update your podcast regularly on your hosting platform. The updates will automatically be reflected on Apple Podcasts through the RSS feed.
