-### Getting started
+### Installation
 
+Resume-schema is intended to be installed as a dependency of your project:
+
+```sh
+npm add resume-schema
 ```
-npm install --save resume-schema
-```
 
-To use
+### Usage
+The main export of this package is an object that validates as a [JSON schema](https://json-schema.org/understanding-json-schema/). It should work with [any compliant implementation](https://json-schema.org/implementations.html#validator-javascript).
+
+#### validation
+To determine if an object is a valid JSON resume, you can do something like this:
 
 ```js
-var resumeSchema  = require('resume-schema');
-resumeSchema.validate({ name: "Thomas" }, function (err, report) {
-  if (err) {
-    console.error('The resume was invalid:', err);
-    return;
-  }
-  console.log('Resume validated successfully:', report);
-});
-```
+import schema from 'resume-schema';
+import Ajv from 'ajv'; // validator. See https://ajv.js.org/
 
-More likely
+const validate = new Ajv().compile(schema);
 
-```js
-var fs = require('fs');
-var resumeSchema  = require('resume-schema');
-var resumeObject = JSON.parse(fs.readFileSync('resume.json', 'utf8'));
-resumeSchema.validate(resumeObject);
+validate({basics: {name: "Thomas"}}); // true
+validate({invalidProperty: "foo bar"}); // false
 ```
