+<img src="https://travis-ci.org/jondot/mngs.svg?branch=master">
+
+A pleasant CLI for rapid development with Mongoose.
+
+![](media/mngs.gif)
+
+
+## Quickstart
+
+```
+$ yarn add --dev mngs
+```
+
+And add the following script to your `package.json` file:
+
+```json
+"scripts":{
+    "mongoose":"MNGS_MODELS=config/mngs.js mngs"
+}
+```
+
+And here's how `config/mngs.js` looks like:
+
+```javascript
+// connects mongoose. grab your own setup
+require('./mongoose-setup.js')
+
+// exports a map, e.g. { User: <mongoose model>, Post: <mongoose model> }
+const models = require(path.join(__dirname, '../models'))
+module.exports = models
+```
+
+# Usage
+
+Use your models (they are exposed directly) to print `p`, log `l`, and display on a table `t`.
+Additionally you can simulate a `toJSON` with `js` to see what part of your model is exposed.
+
+```
+>> t(User.find())
+>> p(User.find())
+>> l(User.find())
+>> js(User.find())
+```
+
