+# PowerSync SDK for Node.JS
+
+_[PowerSync](https://www.powersync.com) is a sync engine for building local-first apps with instantly-responsive UI/UX and simplified state transfer. Syncs between SQLite on the client-side and Postgres, MongoDB or MySQL on the server-side._
+
+This package (`packages/node`) is the PowerSync SDK for NodeJS clients. It is an extension of `packages/common`.
+Using this package is not necessary for PowerSync on servers, see [our documentation](https://docs.powersync.com/installation/app-backend-setup) for more details on that.
+
+This package has an API similar to the PowerSync web SDK, for which a summary of features is available [here](https://docs.powersync.com/client-sdk-references/js-web).
+
+# Installation
+
+## Install Package
+
+```bash
+npm install @powersync/node
+```
+
+Both `@powersync/node` and the `better-sqlite3` packages have install scripts that need to run to compile
+or download sqlite3 and PowerSync binaries.
+
+# Getting Started
+
+You can follow along our [web SDK reference](https://docs.powersync.com/client-sdk-references/js-web) for the web
+which contains everything you need to know to get started implementing PowerSync in your project.
+Replace imports of `@powersync/web` with `@powersync/node` where necessary.
+
+# Examples
+
+A simple example using `@powersync/node` is available in the [`demos/example-node/`](../demos/example-node) directory.
