-PostgresKit is a library providing an SQLKit driver for PostgresNIO.
+🐘 Non-blocking, event-driven Swift client for PostgreSQL.
+
+### Usage
+
+Reference this package in your `Package.swift` to include it in your project.
+
+```swift
+.package(url: "https://github.com/vapor/postgres-kit.git", from: "2.0.0")
+```

+### Supported Platforms
+
+PostgresKit supports the following platforms:
+
+- Ubuntu 20.04+
+- macOS 10.15+
 
 ## Overview
 
-This package provides the "foundational" level of support for using [Fluent] with PostgreSQL by implementing the requirements of an [SQLKit] driver. It is responsible for:
+PostgresKit is an [SQLKit] driver for PostgreSQL clients. It supports building and serializing Postgres-dialect SQL queries. PostgresKit uses [PostgresNIO] to connect and communicate with the database server asynchronously. [AsyncKit] is used to provide connection pooling.
+
+> Important: It is strongly recommended that users who leverage PostgresKit directly (e.g. absent the Fluent ORM layer) take advantage of PostgresNIO's [PostgresClient] API for connection management rather than relying upon the legacy AsyncKit API.
+
+### Configuration
+
+Database connection options and credentials are specified using a ``SQLPostgresConfiguration`` struct. 
+
+```swift
+import PostgresKit
+
+let configuration = SQLPostgresConfiguration(
+    hostname: "localhost",
+    username: "vapor_username",
+    password: "vapor_password",
+    database: "vapor_database"
+)
+```
+
+URL-based configuration is also supported.
+
+```swift
+guard let configuration = SQLPostgresConfiguration(url: "postgres://...") else {
+    ...
+}
+```
+
+To connect via unix-domain sockets, use ``SQLPostgresConfiguration/init(unixDomainSocketPath:username:password:database:)`` instead of ``SQLPostgresConfiguration/init(hostname:port:username:password:database:tls:)``.
+
+```swift
+let configuration = PostgresConfiguration(
+    unixDomainSocketPath: "/path/to/socket",
+    username: "vapor_username",
+    password: "vapor_password",
+    database: "vapor_database"
+)
+```
+
+### Connection Pool
+
+Once you have a ``SQLPostgresConfiguration``, you can use it to create a connection source and pool.
+
+```swift
+let eventLoopGroup: EventLoopGroup = NIOSingletons.posixEventLoopGroup
+let pools = EventLoopGroupConnectionPool(
+    source: PostgresConnectionSource(configuration: configuration), 
+    on: eventLoopGroup
+)
+
+// When you're done:
+try await pools.shutdownAsync()
+```
+
+First create a ``PostgresConnectionSource`` using the configuration struct. This type is responsible for creating new connections to your database server as needed.
+
+Next, use the connection source to create an `EventLoopGroupConnectionPool`. You will also need to pass an `EventLoopGroup`. For more information on creating an `EventLoopGroup`, visit [SwiftNIO's documentation]. Make sure to shutdown the connection pool before it deinitializes. 
+
+`EventLoopGroupConnectionPool` is a collection of pools for each event loop. When using `EventLoopGroupConnectionPool` directly, random event loops will be chosen as needed.
+
+```swift
+pools.withConnection { conn 
+    print(conn) // PostgresConnection on randomly chosen event loop
+}
+```
+
+To get a pool for a specific event loop, use `pool(for:)`. This returns an `EventLoopConnectionPool`. 
+
+```swift
+let eventLoop: EventLoop = ...
+let pool = pools.pool(for: eventLoop)
+
+pool.withConnection { conn
+    print(conn) // PostgresConnection on eventLoop
+}
+```
+
+### PostgresDatabase
+
+Both `EventLoopGroupConnectionPool` and `EventLoopConnectionPool` can be used to create instances of `PostgresDatabase`.
 
-- Managing the underlying PostgreSQL library ([PostgresNIO]),
-- Providing a two-way bridge between PostgresNIO and SQLKit's generic data and metadata formats, and
-- Presenting an interface for establishing, managing, and interacting with database connections via [AsyncKit].
+```swift
+let postgres = pool.database(logger: ...) // PostgresDatabase
+let rows = try postgres.simpleQuery("SELECT version();").wait()
+```
 
-> Important: It is strongly recommended that users who leverage PostgresKit directly (e.g. absent the Fluent ORM layer) take advantage of PostgresNIO's [PostgresClient] API for connection management rather than relying upon the legacy AsyncKit-based support.
+Visit [PostgresNIO's docs] for more information on using `PostgresDatabase`.
 
-> Tip: A FluentKit driver for PostgreSQL is provided by the [FluentPostgresDriver] package.
+### SQLDatabase
 
-## Version Support
+A `PostgresDatabase` can be used to create an instance of `SQLDatabase`.
 
-This package uses [PostgresNIO] for all underlying database interactions. It is compatible with all versions of PostgreSQL and all platforms supported by that package.
+```swift
+let sql = postgres.sql() // SQLDatabase
+let planets = try sql.select().column("*").from("planets").all().wait()
+```
 
-> Caution: There is one exception to the above at the time of this writing: This package requires Swift 5.8 or newer, whereas PostgresNIO continues to support Swift 5.6.
+Visit [SQLKit's docs] for more information on using `SQLDatabase`.
