+
+**Return single parameter value (matches both GET, POST, FILE):**
+```php
+$value = Request::getInstance()->getInput()->get('name');
+```
+
+**Return parameter object (matches both GET, POST, FILE):**
+```php
+$object = Request::getInstance()->getInput()->getObject('name');
+```
+
+**Return specific GET parameter (where name is the name of your parameter):**
+```php
+$object = Request::getInstance()->getInput()->get->name;
+$object = Request::getInstance()->getInput()->post->name;
+$object = Request::getInstance()->getInput()->file->name;
+```
+
+**Return all parameters:**
+```php
+// Get all
+$objects = Request::getInstance()->getInput()->all();
+
+// Only match certain keys
+$objects = Request::getInstance()->getInput()->all([
+    'company_name',
+    'user_id'
+]);
+```
+
+All object inherits from `InputItem` class and will always contain these methods:
+- `getValue()` - returns the value of the input.
+- `getIndex()` - returns the index/key of the input.
+- `getName()` - returns a human friendly name for the input (company_name will be Company Name etc).
+
+`InputFile` has the same methods as above along with some other file-specific methods like:
+- `getTmpName()` - get file temporary name.
+- `getSize()` - get file size.
+- `move($destination)` - move file to destination.
+- `getContents()` - get file content.
+- `getType()` - get mime-type for file.
+- `getError()` - get file upload error.
+
+
+### Easy access your input
+Create a helper function to easily get access to the input elements.
+
+Example:
+
+```php
+/**
+ * Get input class
+ * @return \Pecee\Http\Input\Input
+ */
+function input() {
+    return \Pecee\Http\Request::getInstance()->getInput();
+}
+```
+
+Then you can easily do something like this in your controller:
+
+```php
+// Get parameter site_id or default-value 2
+$value = input()->get('site_id', '2');
+```

+# Simple PHP router demo project
+
+This project is here to give you a basic understanding of how to setup and using simple-php-router.
+
+Please note that this demo-project only covers how to integrate the `simple-php-router` in a project without a framework. If you are using some sort of PHP framework in your project the implementation might vary.
+
+**What we won't cover:**
+
+- How to setup a solution that fits your need. This is a basic demo to help you get started.
+- Understanding of MVC; including Controllers, Middlewares or ExceptionHandlers.
+- How to integrate into third party frameworks.
+
+**What we cover:**
+
+- How to get up and running fast - from scratch.
+- How to get ExceptionHandlers, Middlewares and Controllers working.
+- How to setup your webservers.
+
+## Installation
+
+- Navigate to the `demo-project` folder in terminal and run `composer update` to install the latest version.
+- Point your webserver to `demo-project/public`.
+
+### Setting up Nginx
+
+If you are using Nginx please make sure that url-rewriting is enabled.
+
+You can easily enable url-rewriting by adding the following configuration for the Nginx configuration-file for the demo-project.
+
+```
+location / {
+    try_files $uri $uri/ /index.php?$query_string;
+}
+```
+
+### Setting up Apache
+
+Nothing special is required for Apache to work. We've include the `.htaccess` file in the `public` folder. If rewriting is not working for you, please check that the `mod_rewrite` module (htaccess support) is enabled in the Apache configuration.
+
+## Folder structure
+
+| Folder        | Description |
+| ------------- |-------------|
+| app            |Contains projects-specific PHP classes|
+| public         |Public folder which are accessible through the web.|
+
+## Notes
+
+The demo project has it's own `Router` class implementation which extends the `SimpleRouter` class with further functionality. 
+This class can be useful adding additional functionality that are required before and after routing occurs or any extra functionality belonging to the router itself. 
+
+In this project we also use our custom router-class to autoload the `routes.php` file from our custom location (`app/routes.php`).
+
+Please check the `routes.php` file in `demo-project/app` for all the urls/rules available in the project.
+
+### CSRF-verifier
+
+For the purpose of this demo, we've added a custom CSRF-verifier middleware called `CsrfVerifier` and disabled CSRF checks for all calls to `/api/*`. This will ensure that CSRF form-checks are not applied when calling our demo api url.
+
+### Exception handlers
+
+The included `CustomExceptionHandler` class returns a very basic json response for errors received on calls to `/api/*` or otherwise just a simple formatted error response.
+
+### Middlewares
+
+`ApiVerification` class is added to all calls to `/api/*`. This simple class just adds some data to the `Request` object, which is returned in one of the methods in the `ApiController` class. We've added this class to demonstrate that you can use middlewares to ensure that the user has the correct authentication - before router loads the controller itself.
+
+### Urls
+
+Please see `routes.php` for all routes and rules.
+
+| URL        |
+| ------------- |
+| /             |
+| /api/demo       |
+| /companies       |
+| /companies/[id]  |
+| /contact         |
