+# DocumentHandler
+
+Open a document (e.g. PDF) with a corresponding native app.
+
+Since ``Application.OpenURL(...path)`` is not working (anymore?) to open local files on iOS, I searched the internet for another solution (see credits). I found usable code and want to make it more accessible.
+
+## How to install
+
+Just add the plugin via Package Manager with the git url:  
+
+```
+https://github.com/Draudastic26/document-handler.git#upm
+```
+
+## Usage
+
+```csharp
+using drstc.DocumentHandler;
+...
+DocumentHandler.OpenDocument(somePath);
+```
+
+## Notes
+
+I just tested this on iOS with a PDF file. Please let me know if you tested this with other document types.
+
+## Contribution
+
+Feel free to create a pull request or an issue!
