+## Privacy and Information Permanence
+
+Relays know your IP address, your name, your location (guessed from IP), your pub key, all your contacts, and other relays, and can read every action you do (post, like, boost, quote, report, etc) except for Private Zaps and Private DMs. While the content of direct messages (DMs) is only visible to you and your DM counterparty, everyone can see when you and your counterparty DM each other.
+
+If you want to improve your privacy, consider utilizing a service that masks your IP address (e.g. a VPN or Tor) from trackers online.
+
+The relay also learns which public keys you are requesting, meaning your public key will be tied to your IP address.
+
+Information shared on Nostr can be re-broadcasted to other servers and should be assumed permanent for privacy purposes. There is no way to guarantee the deletion of any content once posted.

 # Development Overview
 
-## Overall Architecture
+This repository is split between Amethyst and Quartz:
+- Amethyst is a native Android app made with Kotlin and Jetpack Compose.
+- Quartz is our own Nostr-commons library to host classes that are of interest to other Nostr Clients.
 
-This is a native Android app made with Kotlin and Jetpack Compose.
-The app uses a modified version of the [nostrpostrlib](https://github.com/Giszmo/NostrPostr/tree/master/nostrpostrlib) to talk to Nostr relays.
-The overall architecture consists of the UI, which uses the usual State/ViewModel/Composition, the service layer that connects with Nostr relays,
+The app architecture consists of the UI, which uses the usual State/ViewModel/Composition, the service layer that connects with Nostr relays,
 and the model/repository layer, which keeps all Nostr objects in memory, in a full OO graph.
 
-The repository layer stores Nostr Events as Notes and Users separately. Those classes use LiveData objects to
+The repository layer stores Nostr Events as Notes and Users separately. Those classes use LiveData and Flow objects to
 allow the UI and other parts of the app to subscribe to each Note/User and receive updates when they happen.
-They are also responsible for updating viewModels when needed. Filters react to changes in the screen. As the user
-sees different Events, the Datasource classes are used to receive more information about those particular Events.
+They are also responsible for updating viewModels when needed. As the user scrolls through Events, the Datasource classes
+are updated to receive more information about those particular Events.
 
 Most of the UI is reactive to changes in the repository classes. The service layer assembles Nostr filters for each need of the app,
 receives the data from the Relay, and sends it to the repository. Connection with relays is never closed during the use of the app.
 The UI receives a notification that objects have been updated. Instances of User and Notes are mutable directly.
 There will never be two Notes with the same ID or two User instances with the same pubkey.
 
-Lastly, the user's account information (priv key/pub key) is stored in the Android KeyStore for security.

-# Privacy on Relays & nostr
-Your internet protocol (IP) address is exposed to the relays you connect to. If you want to improve your privacy, consider utilizing a service that masks your IP address (e.g. a VPN) from trackers online.
+## Using the Quartz library
 
-The relay also learns which public keys you are requesting, meaning your public key will be tied to your IP address.
+Setup [JitPack.io](https://jitpack.io/#vitorpamplona/amethyst/v0.84.3) to your build file
 
-Relays have all your data in raw text. They know your IP, your name, your location (guessed from IP), your pub key, all your contacts, and other relays, and can read every action you do (post, like, boost, quote, report, etc) with the exception of Private Zaps and Private DMs.
+Add `maven { url 'https://jitpack.io' }` to settings.gradle at the end of repositories:
 
-# DM Privacy #
-While the content of direct messages (DMs) is only visible to you and your DM counterparty, everyone can see when you and your counterparty DM each other.
