+# credo-ts-message-pickup-repository-pg API Usage Documentation
+
+## Overview
+
+The `PostgresMessagePickupRepository` implements the MessagePickupRepository interface from @credo-ts to manage messaging in live mode. It uses PostgreSQL as the storage backend for all messaging operations and introduces a publish/subscribe system to support multiple instances sharing the same database that need .
+
+This approach centralizes all database operations for a DIDComm Mediator, simplifying its implementation and ensuring seamless scalability across multiple instances.
+
+## Features
+
+- Message storage and retrieval: Save and fetch messages from a PostgreSQL database.
+
+- Pub/Sub integration: Notify other services of new messages using Pub/Sub channels.
+
+- Live session management: Handle live sessions for efficient message delivery.
+
+- Database initialization: Automatically set up the database structure required for message operations.
+
+## Installation
+
+To use this module, install package in your Didcomm Mediator App:
+
+```bash
+npm i @2060.io/credo-ts-message-pickup-repository-pg
+```
+
+## Usage
+
+Instance `PostgresMessagePickupRepository` with requires explicit configuration defined in `PostgresMessagePickupRepositoryConfig` type through its constructor to set up the PostgreSQL connection and Logger. Ensure to provide the necessary database credentials when creating an instance of the repository.
+
+### Example Configuration
+
+```javascript
+const messageRepository = new PostgresMessagePickupRepository({
+  logger: yourLoggerInstance,
+  postgresUser: 'your_postgres_user',
+  postgresPassword: 'your_postgres_password',
+  postgresHost: 'your_postgres_host',
+  postgresDatabaseName: 'your_database_name',
+})
+```
+
+### Initializing the Repository
+
+To start using the `PostgresMessagePickupRepository`, initialize it with an agent and a callback function for retrieving connection information.
+
+Note that in this example, notification token is stored as a tag in connection records, so it is used to determine whether to create a Push notification callback or not for a given DIDComm connection.
+
+```javascript
+const connectionInfoCallback = async (connectionId) => {
+          const connectionRecord = await this.agent.connections.findById(connectionId)
+          const token = connectionRecord?.getTag('device_token') as string | null
+          return {
+   sendPushNotification: token ? (messageId) => { this.notificationSender.send(token, messageId }: undefined,
+ }
+}
+await messagePickupRepository.initialize({ agent, connectionInfoCallback })
+```
+
+### Using with a Credo-based DIDComm Mediator
+
+This full example shows how `PostgresMessagePickupRepository` is created an initialized alongside an `Agent` instance:
+
+```javascript
+import { Agent, MediatorModule, MessagePickupModule } from '@credo-ts/core'
+import { agentDependencies } from '@credo-ts/node'
+import { MessageForwardingStrategy } from '@credo-ts/core/build/modules/routing/MessageForwardingStrategy'
+import { PostgresMessagePickupRepository } from './PostgresMessagePickupRepository'
+
+const messagePickupRepository = new PostgresMessagePickupRepository({
+  postgresHost: 'postgres',
+  postgresUser: 'user',
+  postgresPassword: 'pass',
+})
+const agent = new Agent({
+  dependencies: agentDependencies,
+  config: { label: 'Test' },
+  modules: {
+    mediator: new MediatorModule({ messageForwardingStrategy: MessageForwardingStrategy.QueueOnly }),
+    messagePickup: new MessagePickupModule({
+      messagePickupRepository,
+    }),
+  },
+})
+
+const notificationSender = // { your implementation of a Push notification service }
+const connectionInfoCallback = async (connectionId: string) => {
+  const connectionRecord = await agent.connections.findById(connectionId)
+
+  const token = connectionRecord?.getTag('device_token') as string | null
+
+  return {
+    sendPushNotification: token
+      ? (messageId: string) => {
+          notificationSender.send(token, messageId)
+        }
+      : undefined,
+  }
+}
+
+await messagePickupRepository.initialize({ agent, connectionInfoCallback })
+await agent.initialize()
+```
+
+With these steps, you can now use the `PostgresMessagePickupRepository` with your Credo-based DIDComm mediator. Have fun!
