+## Introduction
+
+Generate PDFs using OctoberCMS.
+
+## How to
+
+### Configure environment
+
+After installing you should be ready to go, but in a lot of cases, you will have to set an absolute path to the executable binary of `wkhtmltopdf` in backend settings.
+
+Sometimes you may wish to customize it more:
+
+-   tokenizing - if you want to add pseudorandom 15 chars token to the local filename. It does not affect downloaded filename so is set to `true` by default
+-   directory where generated PDF files will be stored, `temp_path()` by default
+-   removing PDFs files right after sending to the user, `true` by default
+-   removing files older than the specified amount of seconds, two days by default
+
+### Quickstart
+
+Here you have an example `onDownloadPdf` AJAX handler that generates PDF and downloads PDF by October's AJAX framework. As simple as that:
+
+```php
+    use Initbiz\Pdfgenerator\Classes\PdfGenerator;
+
+    ...
+
+    /*
+    * OctoberCMS AJAX handler to download PDF
+    */
+    public function onDownloadPdf()
+    {
+        // Create a new PdfGenerator object with a filename as a parameter
+        $pdfGenerator = new PdfGenerator("my-pdf");
+
+        //Set absolute path of the Twig layout
+        $pdfGenerator->layout = plugins_path().'/initbiz/exampleplugin/views/pdf/pdflayout.htm';
+
+        //Set data which will be sent to the layout
+        $pdfGenerator->data = ['viewData' => 'Value of viewData'];
+
+        $pdfGenerator->generatePdf();
+
+        return $pdfGenerator->downloadPdf();
+    }
+```
+
+### More advanced usage
+
+The plugin comes with a `PdfLayout` class that can be injected to `PdfGenerator`. The above example using the class will look as follows:
+
+```php
+    use Initbiz\Pdfgenerator\Classes\PdfGenerator;
+    use Initbiz\ExamplePlugin\PdfLayouts\ExampleLayout;
+    ...
+
+    /*
+    * OctoberCMS AJAX handler to download PDF
+    */
+    public function onDownloadPdf()
+    {
+        //Set data which will be injected to the layout
+        $data = ['viewData' => 'Value of viewData'];
+
+        $layout = new ExampleLayout($data);
+
+        // Create a new PdfGenerator object with a filename and the layout as parameters
+        $pdfGenerator = new PdfGenerator($filename, $layout);
+
+        $pdfGenerator->generatePdf();
+
+        return $pdfGenerator->downloadPdf();
+    }
+```
+
+You can also send the file directly to the user using October CMS v. 3.1+ `data-request-download` feature.
+
+In this case, change the method name to `downloadPdfDirectly()`.
+
+It is a little cleaner, but take a look at the `ExampleLayout` class:
+
+```php
+    use Initbiz\Pdfgenerator\Classes\PdfLayout;
+
+    class ExampleLayout extends PdfLayout
+    {
+        public function prepareData($data)
+        {
+            parent::prepareData($data);
+
+            $this->data['logo'] = $this->assetsPath.'/img/logo.png';
+            $this->data['mdicss'] = $this->assetsPath.'/css/materialdesignicons.min.css';
+
+            $this->data['fonts'] = [
+                1 => [
+                    'name' => 'Material Design Icons',
+                    'src'  => $this->assetsPath.'/fonts/mdi/materialdesignicons-webfont.svg',
+                    'format' => 'svg'
+                ],
+            ];
+        }
+    }
+```
+
+and the files structure of our `PdfLayouts` directory:
+
+```
+    PdfLayouts
+    ├── examplelayout
+    │   ├── assets
+    │   │   ├── css
+    │   │   │   └── materialdesignicons.min.css
+    │   │   ├── fonts
+    │   │   │   └── mdi
+    │   │   │       └── materialdesignicons-webfont.svg
+    │   │   └── img
+    │   │       └── logo.png
+    │   └── default.htm
+    └── ExampleLayout.php
+```
+
+As you can see it is a OctoberCMS flavoured format. Just create a class and corresponding directory with a lower-cased name.
+
+It is a great way of organizing your PDF layouts with all assets they need to have included. Still keeping it as simple as possible, but not simpler :).
+
+## Troubleshooting and pro tips
+
+### Pro tip #1: fonts format
+
+While working with PDFs you probably will want to beautify them as much as possible. They will be displaying images, custom fonts or icons.
+But sometimes `wkhtmltopdf` messes up a little.
+
+#### Artifacts in rounded letters (O, B, P, R, etc...)
+
+If you have included font using `TrueType` (`ttf`), then try to change it to `OpenType` (`otf`). If you do not have the file, then look for online converters. They are doing it pretty well.
+
+#### Material Design Icons and Adobe Reader
+
+If you add `Material Design Icons` (probably MDI are not the only case) Adobe Reader can have problems with reading the PDF (error 135). In this case, you should change `MDI` to the SVG version as in the above example. Then they appear as normal images.
