Unable to create form tag in Laravel 5

Directory structure.

My current code is below

{{ Form::open(array('action' =>  'SkillsController@store', 'method'  =>  'POST' }}

{{ Form::close() }}

I got the following error

Class 'Form' not found

{{!! Form::open(array('action' =>  'SkillsController@store', 'method'  =>  'POST'}}

{{!! Form::close() !!}}

Still I am facing the same issue.
