-# Intro
+# PZP Docs
 
-Let's discover **Docusaurus in less than 5 minutes**.
+What is "PZP":
+- A local-first P2P protocol with 10 years of learnings baked in
+- Message formats + Message validation + RPC methods
+- If scuttlebutt is :slightly_smiling_face: then pzp is :sunglasses: 
 
-## Getting Started
+What it doesn't specify:
+- Disk storage
 
-Get started by **creating a new site**.
+## Features
 
-Or **try Docusaurus immediately** with **[docusaurus.new](https://docusaurus.new)**.
+- sig-chains - you know what the messages are
+- first class multi-device support
+- partial replication (using lipmaa links)
+- message deletion (can leave nothing, or only metadata)
 
-### What you'll need
+### How PZP is different from SSB (Secure Scuttlebutt)
 
-- [Node.js](https://nodejs.org/en/download/) version 16.14 or above:
-  - When installing Node.js, you are recommended to check all checkboxes related to dependencies.
+- Storage is designed to not grow indefinitely. By default (of course overridable) an app's storage shouldn't go above 100MB.
+- Multi device/app support from the start. Every device/app has its own keypair. They're connected together into one identity using an Account tangle. The Account tangle's root message ID is the account's identifier.
+- One account or even keypair can post messages concurrently (forking) without problem. Because there aren't linear feeds, everything is in tangles.
+- Deletion is possible. The data contents of a message is separate from the message metadata, and only the metadata + hash of the data is signed.
 
-## Generate a new site
+### How PZP is different from Nostr
 
-Generate a new Docusaurus site using the **classic template**.
+- keys are not shared across devices
+- sig-chains - you know if you're missing content in PZP
 
-The classic template will automatically be added to your project after you run the command:
+## Tangles
 
-```bash
-npm init docusaurus@latest my-website classic
+Tangles control how messages are organised. They provide a way to group, and causally sort (partially), which is important for replication.
+
+Basics of tangles in PZP: it's a directed acyclic graph (DAG) which aims to be as linear as possible
+
+```mermaid
+flowchart RL
+
+E --> D --> C --> A
+      D --> B --> A
 ```
+There are 3 sorts of tangles:
 
-You can type this command into Command Prompt, Powershell, Terminal, or any other integrated terminal of your code editor.
+- Account - a tangle which weaves (device) keys and defines capabilities / permissions of these
+- Feed - a tangle where all messages are from valid devices (as defined by an Account), and scoped to a particular domain
+  - e.g. all post messages from "mix"
+  - e.g. all chess messages from "happy0"
+- Thread - a tangle where multiple Accounts are collaborating on some state
+  - e.g. all the messages making up a "10th birthday gathering"
+  - e.g. all the messages in a discussion
+  - e.g. all the messages in a shared shopping list
 
-The command also installs all necessary dependencies you need to run Docusaurus.
+### Account Tangle
 
-## Start your site
+The account tangle starts with a message which says "This key is allowed to author messages on behalf of this account, and add further keys".
 
-Run the development server:
+Subsequent messages in this tangle may add / remove capabilities for existing / new keys.
 
-```bash
-cd my-website
-npm run start
-```
+Messages in this tangle are verified by checking state they're extending on
 
-The `cd` command changes the directory you're working with. In order to work with your newly created Docusaurus site, you'll need to navigate the terminal there.
 
-The `npm run start` command builds your website locally and serves it through a development server, ready for you to view at http://localhost:3000/.
+### Feed Tangle
+
+_Domain Tangle, AccountDomain Tangle_
+
+
+### Thread Tangle
+
+All tangles have
+- a root / root message
+- an ID (the id of the root message of the tangle)
+- have tangle-data for causal ordering
+
+How the tangles differ
+- the Account tangle has strict validation of messages (it is only valid to write to it if you've been given permission to)
+- a Feed root is deterministic! (only inputs are accountId + domain)
