Podcasters can offer their members access to exclusive episodes. If you support a podcast as a member, you will get access to these episodes. More specifically, you'll get a personalized audio RSS feed URL that you will then need to copy into your podcast or RSS app.
Here’s how it works:
Go to the menu and click on Memberships (all the plans you have purchased are listed here)
Click on the podcast button in the corresponding plan
Confirm in the next step with Continue
Then select a Reader app that you want to associate with your personalized Steady audio RSS feed

You only need to do this once. Then you will automatically receive new exclusive episodes from the podcast you support.
