 # feathers-hooks-csvtoarray
 Feathers hook for converting a comma-delimited list to an Array of strings.
+
+## Installing
+
+Simply run `npm install --save feathers-hooks-csvtoarray` and you're good to go!
+
+## Usage
+
+> **Important:** As of version 0.1.0, this hook is intended to use with Sequelize. Further versions will move the coupling code to hook configurations.
+
+Require the hook:
+
+```js
+const csvToArray = require('feathers-hooks-csvtoarray');
+```
+
+Then, choose which fields in your Sequelize Model should be parsed by the hook, adding the option `csvAsArray: true`:
+
+```js
+// things.model.js
+const Sequelize = require('sequelize');
+
+module.exports = function (app) {
+  const sequelizeClient = app.get('sequelizeClient');
+  const things = sequelizeClient.define('things', {
+    id: {
+      type: Sequelize.CHAR(100),
+      allowNull: false,
+      primaryKey: true
+    },
+    names: {
+      type: Sequelize.CHAR(200),
+      allowNull: false,
+      csvAsArray: true // this will be parsed by csvtoarray
+    }, {}
+  });
+
+  return things;
+};
+```    
+
+Finally, bind the hook to the model's service.
+
+```js
+app.service('things').hooks({
+  after: {
+    find: [ csvToArray() ],
+    get: [ csvToArray() ]
+  }
+});
+```
