 ## Install
 
-> For koa@>=2.x (next):
+> For versions of Koa &lt;2.x please use `koa-csrf@2.x`
+
+[npm][]:
 
-```bash
-npm install --save koa-csrf@3.x
+```sh
+npm install koa-csrf
 ```
 
-> For koa@<2.x:
+[yarn][]:
 
-```bash
-npm install --save koa-csrf@2.x
+```sh
+yarn add koa-csrf
 ```
 
 
 ## Usage
 
 1. Add middleware in Koa app (default options are shown):
-  ```js
-  import Koa from 'koa';
-  import bodyParser from 'koa-bodyparser';
-  import session from 'koa-generic-session';
-  import convert from 'koa-convert';
-  import CSRF from 'koa-csrf';
 
-  const app = new Koa();
+   ```js
+   const Koa require('koa');
+   const bodyParser require('koa-bodyparser');
+   const session require('koa-generic-session');
+   const convert require('koa-convert');
+   const CSRF require('koa-csrf');
+
+   const app = new Koa();
+
+   // set the session keys
+   app.keys = [ 'a', 'b' ];
+
+   // add session support
+   app.use(convert(session()));
+
+   // add body parsing
+   app.use(bodyParser());
+
+   // add the CSRF middleware
+   app.use(new CSRF({
+     invalidTokenMessage: 'Invalid CSRF token',
+     invalidTokenStatusCode: 403,
+     excludedMethods: [ 'GET', 'HEAD', 'OPTIONS' ],
+     disableQuery: false
+   }));
+
+   // your middleware here (e.g. parse a form submit)
+   app.use((ctx, next) => {
+     if (![ 'GET', 'POST' ].includes(ctx.method))
+       return next();
+     if (ctx.method === 'GET') {
+       ctx.body = ctx.csrf;
+       return;
+     }
+     ctx.body = 'OK';
+   });
+
+   app.listen();
+   ```
 
-  // set the session keys
-  app.keys = [ 'a', 'b' ];
+2. Add the CSRF token in your template forms:
 
-  // add session support
-  app.use(convert(session()));
+   > Jade Template:
 
-  // add body parsing
-  app.use(bodyParser());
+   ```jade
+   form(action='/register', method='POST')
+     input(type='hidden', name='_csrf', value=csrf)
+     input(type='email', name='email', placeholder='Email')
+     input(type='password', name='password', placeholder='Password')
+     button(type='submit') Register
+   ```
 
-  // add the CSRF middleware
-  app.use(new CSRF({
-    invalidSessionSecretMessage: 'Invalid session secret',
-    invalidSessionSecretStatusCode: 403,
-    invalidTokenMessage: 'Invalid CSRF token',
-    invalidTokenStatusCode: 403,
-    excludedMethods: [ 'GET', 'HEAD', 'OPTIONS' ],
-    disableQuery: false
-  }));
+   > EJS Template:
 
-  // your middleware here (e.g. parse a form submit)
-  app.use((ctx, next) => {
+   ```ejs
+   <form action="/register" method="POST">
+     <input type="hidden" name="_csrf" value="<%= csrf %>" />
+     <input type="email" name="email" placeholder="Email" />
+     <input type="password" name="password" placeholder="Password" />
+     <button type="submit">Register</button>
+   </form>
+   ```
 
-    if (![ 'GET', 'POST' ].includes(ctx.method))
-      return next();
 
-    if (ctx.method === 'GET') {
-      ctx.body = ctx.csrf;
-      return;
-    }
+## Options
 
-    ctx.body = 'OK';
+* `invalidTokenMessage` (String or Function) - defaults to `Invalid CSRF token`, but can also be a function that accepts one argument `ctx` (useful for i18n translation, e.g. using `ctx.request.t('some message')` via [@ladjs/i18n][]
+* `invalidTokenStatusCode` (Number) - defaults to `403`
+* `excludedMethods` (Array) - defaults to `[ 'GET', 'HEAD', 'OPTIONS' ]`
+* `disableQuery` (Boolean) - defaults to `false`
 
-  });
 
-  app.listen();
-  ```
