-# Awesome Project Build with TypeORM
+# Using CrateDB with TypeORM
 
-Steps to run this project:
 
-1. Run `npm i` command
-2. Setup database settings inside `data-source.ts` file
-3. Run `npm start` command
+## About
+
+[TypeORM] is an ORM that can run in NodeJS, Browser, Cordova, PhoneGap, Ionic,
+React Native, NativeScript, Expo, and Electron platforms and can be used with
+TypeScript and JavaScript (ES5, ES6, ES7, ES8).
+
+
+## Details
+
+This example shows the canonical TypeORM example project using CrateDB. It has
+been scaffolded using this command:
+```shell
+npx typeorm init --name . --database postgres --express
+```
+A few adjustments have been made because CrateDB does not support the `SERIAL`
+data type.
+
+
+## Data Model
+
+The data model for the `User` entity is defined in [`User.ts`](./src/entity/User.ts).
+
+
+## Usage
+
+```shell
+# Install dependencies.
+npm install
+
+# Run program.
+npm start
+```
+
+
+## Development
+
+Link a TypeORM working tree to a downstream project.
+
+```shell
+cd /path/to/somewhere
+git clone https://github.com/crate-workbench/typeorm --branch cratedb
+cd typeorm
+npm run package
+cd build/package
+npm link
+
+cd /path/to/here
+npm link typeorm
+```
