-Treetracker queue client for Python
+# Treetracker queue Python client for PostgreSQL
+
+This Python project provides asynchronous pub-sub (publish-subscribe) functionality using PostgreSQL as a message broker, leveraging `aiopg` for asynchronous PostgreSQL connections and `psycopg2` for handling PostgreSQL notifications.
+
+## Features
+
+- **Subscribe**: Listen to PostgreSQL channels for incoming notifications.
+- **Publish**: Send messages to a PostgreSQL queue and notify subscribers.
+
+## Requirements
+
+Make sure you have the following installed:
+
+- **Python 3.7+**
+- **PostgreSQL 9.0+**
+- **aiopg**: Asynchronous PostgreSQL driver for Python.
+- **psycopg2**: PostgreSQL database adapter for Python.
+
+Install the required Python packages using `pip`:
+
+```bash
+pip install aiopg psycopg2
+```
+
+## Database Setup
+
+Before using the client, you will need to set up the necessary PostgreSQL table for testing locally otherwise skip this part:
+
+```sql
+CREATE SCHEMA queue; -- creates a schema called queue
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp"; -- helps us generate uuids
+CREATE TABLE queue.message (
+  id uuid PRIMARY KEY DEFAULT uuid_generate_v4(),
+  channel text,
+  data json,
+  created_at timestamptz,
+  updated_at timestamptz
+); -- creates a table with columns id, channel, data, created_at & updated_at
+ALTER TABLE queue.message ALTER COLUMN created_at SET DEFAULT now();
+ALTER TABLE queue.message ALTER COLUMN updated_at SET DEFAULT now();
+-- above two lines make created_at and updated_at columns to be autopopulated
+
+CREATE OR REPLACE FUNCTION queue.new_message_notify() RETURNS TRIGGER AS $$
+        DECLARE
+        BEGIN
+            PERFORM pg_notify(cast(NEW.channel as text), row_to_json(new)::text);
+            RETURN NEW;
+        END;
+        $$ LANGUAGE plpgsql;
+
+CREATE TRIGGER new_insert_trigger BEFORE INSERT ON queue.message
+            FOR EACH ROW EXECUTE PROCEDURE queue.new_message_notify();
+```
+
+## Usage
+
+### 1. Subscribing to a Channel
+
+To subscribe to a PostgreSQL channel, you can use the `subscribe` method of the `Client` class. It continuously listens for notifications on the given channel.
+
+```python
+import asyncio
+import aiopg
+from client import Client 
+
+dsn = 'dbname=test user=postgres password=yourpassword host=localhost'
+
+async def run_subscriber():
+    async with aiopg.connect(dsn) as conn:
+        await Client.subscribe(conn, 'my_channel')
+
+# Run the subscriber
+asyncio.run(run_subscriber())
+```
+
+### 2. Publishing to a Channel
+
+To publish a message to a PostgreSQL channel, use the `publish` method. It inserts a message into the `queue.message` table and notifies listeners.
+
+```python
+import asyncio
+from client import Client
+
+dsn = 'dbname=test user=postgres password=yourpassword host=localhost'
+
+async def run_publisher():
+    await Client.publish(dsn, 'my_channel', 'Hello, PostgreSQL!')
+
+# Run the publisher
+asyncio.run(run_publisher())
+```
+
+### Example Output
+
+- When you publish a message, you’ll see:
+
+  ```
+  Postgres message dispatch success: (1, 'my_channel', 'Hello, PostgreSQL!')
+  ```
+
+- When you subscribe to a channel, you’ll receive:
+
+  ``` 
+  Receive <- Hello, PostgreSQL!
+  ```
+
+## Methods
+
+### `subscribe(conn, channel: str)`
+
+Listens for notifications on a PostgreSQL channel.
+
+- **Parameters**:
+  - `conn`: The `aiopg.Connection` object.
+  - `channel`: The PostgreSQL channel name.
+
+- **Returns**: Prints out the messages received from the channel.
+
+### `publish(dsn: str, channel: str, data: str)`
+
+Publishes a message to a PostgreSQL channel by inserting data into the `queue.message` table.
+
+- **Parameters**:
+  - `dsn`: The PostgreSQL connection string.
+  - `channel`: The PostgreSQL channel to notify.
+  - `data`: The message to be published.
+
+- **Returns**: Inserts a row into the `queue.message` table and notifies the channel subscribers.
+
+## Error Handling
+
+- The code catches and handles common PostgreSQL errors during subscription and publishing.
+- It also ensures that listeners receive a 'finish' message, signaling the end of notifications.
