Step 1 - Install nostr:nprofile1qqs83nn04fezvsu89p8xg7axjwye2u67errat3dx2um725fs7qnrqlgzqtdq0 from their GitHub release page.

Step 2 - Install Amber from Zapstore and import your nsec to Amber from wherever you currently have it stored.

Step 3 - Log into Zapstore with Amber and set up Nostr Wallet Connect if you have a compatible wallet, so you can zap the devs.

Step 4 - Install Amethyst from Zapstore and log into it with Amber.

Step 5 - Install Pokey from Zapstore and log into it with Amber.

Step 6 - Install Citrine relay from Zapstore and add it as a local relay in Amethyst's settings. You can also download all your existing notes to it to back them up if you want.

Congratulations! You now have a powerhouse of a setup for most of your Nostr needs. Explore Zapstore to find more goodies from there. It has more than just Nostr apps, and you can even install Obtainium from Zapstore, too. Though... There are very few apps I have in Obtainium that I couldn't just get from Zapstore instead.
