+- support for handling multiple files
+
+## Upcoming Features
+

+
+## Requirements  
+
+It is recommended to install this package with **PHP version 7.2+** and **Laravel Framework version 5.5+**   
+
+## Installation
+
+```
+composer require oldravian/multi-source-file-uploader
+```
+
+## Configuration
+
+Copy configuration to your project:
+
+```
+php artisan vendor:publish --provider="OldRavian\FileUploader\FileUploaderServiceProvider"
+```
+
+By executing above command the package configuration will be published to **config/old-ravian-file-uploader.php**
+
+
+## Usage
+
+Firstly, you need to initialize the specific FileUploader instance using ```FileUploaderFactory```  
+```php
+$file_uploader_factory = new \OldRavian\FileUploader\Factories\FileUploaderFactory();
+$file_uploader = $file_uploader_factory->build(here you need to provide the file source name, it could be "object", "url" or "base64");
+```
+
+
+## Upload File From Object
+In your controller method:
+
+```php
+
+public function uploadFile(Request $request)
+{
+  $uploadSettings = ["directory"=>"mention directory", "disk"=>"mention disk", "maxFileSize"=>"mention size in bytes", "allowedExtensions"=>[mention extensions]];
+  $file_uploader_factory = new \OldRavian\FileUploader\Factories\FileUploaderFactory();
+  $file_uploader = $file_uploader_factory->build("object");
+   
+  //first parameter should be an instance of \Illuminate\Http\UploadedFile
+  //second parameter is optional, if you leave that parameter then default settings will be used
+  $data = $file_uploader->upload($request->file, $uploadSettings); //it will return an array
+}
+``` 
+
+**$uploadSettings** is an asociative array with the following possible keys:   
+- ```directory```: the root directory containing your uploaded files  
+- ```disk```: the storage disk for file upload. Check Laravel official documentation for more details, e.g: ```public```, ```s3```  
+- ```maxFileSize``` (in bytes): the maximum size of an uploaded file 
+- ```allowedExtensions```: array of acceptable file extensions, e.g: ```['jpg', 'png', 'pdf']```  
+
+The backend default settings are as follows:  
+```
+- 'directory': 'media'
+- 'disk': 'public'
+- 'maxFileSize':  50 MB
+- 'allowedExtensions': 'png','jpg','jpeg','mp4','doc','docx','ppt','pptx','xls','xlsx','txt','pdf'
+```
+
+You can change these default settings by using the following environment variables in .env:  
+- ```OLDRAVIAN_File_UPLOADER_DEFAULT_DISK```
+- ```OLDRAVIAN_File_UPLOADER_DEFAULT_DIRECTORY```
+- ```OLDRAVIAN_File_UPLOADER_DEFAULT_MAX_FILE_SIZE``` (in bytes)
+
+If the upload succeeds,```$file_uploader->upload($request->file, $uploadSettings)``` will return the following data for being further persisted to database:  
+
+```php
+[
+    'filename' => 'uploaded file name',
+    'path' => 'path to file location relative to the disk storage',
+    'url' => 'public url to access the file in browser'
+]
+```
+
+If the uploaded file is not valid, then ```false``` will be returned and an error message will be set for ```$file_uploader->uploadError```  
+
+## Upload File From URL
+
+```php
+
+$file_uploader_factory = new \OldRavian\FileUploader\Factories\FileUploaderFactory();
+$file_uploader = $file_uploader_factory->build("url");
+
+//first parameter should be a string url
+//second parameter is optional, if you leave that parameter then default settings will be used
+$data = $file_uploader->upload($request->url, $uploadSettings);
+``` 
+
+
+## Upload File From Base64 Encoded data
+
+```php
+
+$file_uploader_factory = new \OldRavian\FileUploader\Factories\FileUploaderFactory();
+$file_uploader = $file_uploader_factory->build("base64");
+
+//first parameter should be a string (base64 encoded string)
+//second parameter is optional, if you leave that parameter then default settings will be used
+$data = $file_uploader->upload($request->base64_str, $uploadSettings);
+``` 
+
+
+
+## Handling Multiple File Uploads
+
+```php
+
+$file_uploader_factory = new \OldRavian\FileUploader\Factories\FileUploaderFactory();
+$file_uploader = $file_uploader_factory->build("object or url or base64");
+
+$urls_array = ["first file url", "second file url", "third file url"];
+//first parameter should be an array (it could be an array of objects or urls or base64 encoded strings array based on what you mentioned in the above line)
+//second parameter is optional, if you leave that parameter then default settings will be used
+$data_array = $file_uploader->uploadMany($urls_array, $uploadSettings); //$data_array is a 2d array
+```
