 # python-nostr
-A Python library for making Nostr clients
+A Python library for making [Nostr](https://github.com/nostr-protocol/nostr) clients
 
-# Details
-This library can handle basic [Nostr](https://github.com/nostr-protocol/nips) operations described in NIP-01.
+## Usage
+**Generate a key**
+```python
+from nostr.key import generate_private_key, get_public_key
 
-It leverages [websocket-client](https://github.com/websocket-client/websocket-client) for websocket operations and [secp256k1-py](https://github.com/rustyrussell/secp256k1-py) for key operations.
+private_key = generate_private_key()
+public_key = get_public_key(private_key)
+```
+**Connect to relays**
+```python
+from nostr.relay_manager import RelayManager
 
-# Installation
+relay_manager = RelayManager()
+relay_manager.add_relay("wss://nostr-pub.wellorder.net", True, True)
+relay_manager.add_relay("wss://relay.damus.io", True, True)
+relay_manager.open_connection()
+
+while relay_manager.message_pool.has_notices():
+  notice_msg = relay_manager.message_pool.get_notice()
+  print(notice_msg.content)
+```
+**Publish to relays**
+```python
+from nostr.event import Event
+from nostr.relay_manager import RelayManager
+from nostr.message_type import ClientMessageType
+from nostr.key import generate_private_key, get_public_key
+
+relay_manager = RelayManager()
+relay_manager.add_relay("wss://nostr-pub.wellorder.net", True, True)
+relay_manager.add_relay("wss://relay.damus.io", True, True)
+relay_manager.open_connection()
+
+private_key = generate_private_key()
+public_key = get_public_key(private_key)
+
+event = Event(public_key, "Hello Nostr")
+event.sign(private_key)
+
+message = json.dumps([ClientMessageType.EVENT, event.to_json_object()])
+relay_manager.publish_message(message)
+```
+**Receive events from relays**
+```python
+from nostr.filter import Filter, Filters
+from nostr.event import Event, EventKind
+from nostr.relay_manager import RelayManager
+from nostr.message_type import ClientMessageType
+from nostr.key import generate_private_key, get_public_key
+
+filters = Filters([Filter(authors=["<a nostr pubkey in hex>"], kinds=[EventKind.TEXT_NOTE])])
+subscription_id = "<a string to represent subscription id>"
+request = [ClientMessageType.REQUEST, subscription_id]
+request.extend(filters.to_json_array())
+
+relay_manager = RelayManager()
+relay_manager.add_relay("wss://nostr-pub.wellorder.net", True, True)
+relay_manager.add_relay("wss://relay.damus.io", True, True)
+relay_manager.add_subscription(subscription_id, filters)
+relay_manager.open_connection()
+
+message = json.dumps(request)
+relay_manager.publish_message(message)
+
+while relay_manager.message_pool.has_events():
+  event_msg = relay_manager.message_pool.get_event()
+  print(event_msg.event.content)
+```

+## Installation
 1. Clone repository \
 ```git clone https://github.com/jeffthibault/python-nostr.git```
 2. Install dependencies in repo \
 ```python -m venv venv``` \
 ```pip install -r requirements.txt```
 
-Note 1: I wrote this with Python 3.9.5.<br />
-Note 2: If the pip install fails, you might need to install wheel. Try ```pip install wheel```.
+Note: If the pip install fails, you might need to install wheel. Try ```pip install wheel``` then ```pip install -r requirements.txt```
 
-# Disclaimer
-This library is in very early development and still a WIP.<br /> 
-More NIPs will be handled.<br />
-There are probably bugs.<br />
-I need to add tests.<br />
-I will try to publish this as a [PyPI](https://pypi.org/) package at some point.<br />
+## Dependencies
+- [websocket-client](https://github.com/websocket-client/websocket-client) for websocket operations
+- [secp256k1](https://github.com/rustyrussell/secp256k1-py) for key generation, signing, and verifying
+- [cryptography](https://github.com/pyca/cryptography) for encrypting and decrypting direct messages
+
+Note: I wrote this with Python 3.9.5.
