+## Overview
+
+This is the Postgres Adapter for [`next-auth`](https://next-auth.js.org). This package can only be used in conjunction with the primary `next-auth` package. It is not a standalone package.
+
+You can find the SQL schema in the docs at https://github.com/nextauthjs/next-auth/blob/main/packages/adapter-postgres/example-schema.sql
+
+If you find any bugs please report them - this adapter is new!
+
+## Getting Started
+
+1. Install `next-auth` and `@next-auth/pg-adapter`. You'll also need the Postgres package `pg`
+itself, though you'll likely have this already,
+
+```js
+npm install next-auth @next-auth/pg-adapter
+npm install pg
+```
+
+2. Add this adapter to your `pages/api/[...nextauth].js` next-auth configuration object.
+
+```js
+import NextAuth from "next-auth"
+import { PostgresAdapter } from "@next-auth/pg-adapter"
+import { Pool } from "pg";
+
+const connectionString = "postgresql://localhost/adapter-postgres-test"
+
+const client = new Pool({
+  connectionString,
+});
+
+// For more information on each option (and a full list of options) go to
+// https://next-auth.js.org/configuration/options
+export default NextAuth({
+  // https://next-auth.js.org/configuration/providers
+  providers: [],
+  adapter: PostgresAdapter(client)
+  ...
+})
+```
