 We are actively developing Feed Generator integration into the Bluesky Personal Data Server (PDS). Though we are reasonably confident about the general shape and interfaces laid out here, these interfaces and implementation details _are_ subject to change.

 - The PDS sends a `getFeedSkeleton` request to the service endpoint declared in the Feed Generator's DID doc
   - This request is authenticated by a JWT signed by the user's repo signing key
 - The Feed Generator returns a skeleton of the feed to the user's PDS
-- The PDS hydrates the feed (user info, post contents, aggregates, etc)
-  - In the future, the PDS will hydrate the feed with the help of an App View, but for now the PDS handles hydration itself

 For users, this should feel like visiting a page in the app. Once they subscribe to a custom algorithm, it will appear in their home interface as one of their available feeds.

    For inspiration, we've provided a very simple feed algorithm (`whats-alf`) that returns all posts related to the titular character of the TV show ALF.

 We've taken care of setting this server up with a did:web. However, you're free to switch this out for did:plc if you like - you may want to if you expect this Feed Generator to be long-standing and possibly migrating domains.
 
 ### Publishing your feed
 
-To publish your feed, go to the script at `scripts/publishFeedGen.ts` & fill in the variables at the top. Examples are included and some are optional. To publish your feed generator, simply run `yarn publishFeed`.

 ### Reimplementing What's Hot
-To reimplement "What's Hot", you may subscribe to the firehose & filter for all posts & likes (ignoring profiles/reposts/follows/etc). You would keep a running tally of likes per post & when a PDS requests a feed, you would send the most recent posts that pass some threshold of likes.
