 An API centric auth server. Uses Sequelize and mariaDB by default.
 
+This server is available via docker hub at krgamestudios/auth-server.

 # Setup
 
 There are multiple ways to run this app - it can run on it's own via `npm start` (for production) or `npm run dev` (for development). it can also run inside docker using `docker-compose up --build` - run `node configure-script.js` to generate docker-compose.yml and startup.sql.

+# TokenProvider
+
+The MERN-template utilizes React's `useContext()` hook to share the auth-server's access token, effectively globally. Here is a quick rundown of how it works.
+
+# Enabling TokenProvider
+
+To enable the TokenProvider component, wrap your App component with it, like so:
+
+```jsx
+import React from 'react';
+import ReactDOM from 'react-dom';
+
+import App from './pages/app';
+import TokenProvider from './pages/utilities/token-provider';
+
+ReactDOM.render(
+	<TokenProvider>
+		<App />
+	</TokenProvider>,
+	document.querySelector('#root')
+);
+```
+
+# Accessing The Access Token
+
+To access the access token from your app, you simply use the `useContext` hook, like so:
+
+```jsx
+import React, { useContext } from 'react';
+import { TokenContext } from '../utilities/token-provider';
+
+const Component = props => {
+	//context
+	const authTokens = useContext(TokenContext);
+
+	//use the access token
+	console.log(authTokens.accessToken);
+
+	return <div />;
+};
+
+export default Component;
+```
+
+# Most Useful Features Provided
+
+The most useful features provided by TokenProvider are:
+
+* `tokenFetch()`, which wraps the `fetch()` API to ensure that your access token is valid
+* `tokenCallback()`, which passes the accessToken as a parameter to any function passed into it
+* `getPayload()`, which returns the payload of the accessToken (including as "email", "username", "admin", and "mod")
+* `accessToken`, this will be falsy if the user is not logged in
+
