When you run across anything that you think worthwhile - a nifty Account, a particular Post, Starter Pack, Feed, whatever - look for the Share button (circled in red here), which lets you choose from a variety of ways to share, including copying the link directly, sending to a different app, etc

That Visit BookSky button will take you to the link, which looks like this - notice that you can Follow All, with just one click, or select specific ones of interest, each with their own individual Follow button

bsky.app/starter-pack...

We will use Booksky as an example - tap on it, and you'll see a screen like this, with a Visit BookSky button

So how do you find Starter Packs that are interesting? Head to this collection of starter packs, which you can search or scroll through

blueskydirectory.com/starter-packs

You can tap on the feed name or description to view it - to see the posts it will show you

You can also tap on the plus sign at the right side of the feed to Follow it, which will also pin it to your home / profile

When you tap on that gray hashtag, it will expand into this selection of Feeds, which you can scroll through, or search if you have a particular term in mind

Unfortunately, the need to streamline the UI (user interface) means that the feed button is fairly obscure - it's just a gray hashtag at the upper right
