One of the best thing about WordPress is that you can update your themes and plugins with one click without having to worry about download and uploading theme .zip files.
Once you have installed the Munk WordPress Theme, any and all future updates we add into the theme can easily be accessed by one click update from the site Dashboard.
Every time a theme is updated, you will receive a notification in your site’s dashboard that there is a new update to your theme.
All you have to do is click on on “Update Now” button after selecting the theme and it will be automatically update to the new version.
Method 1

To check a theme update navigate to
Dashboard >> Updates.
If there is any update available then it will show you the theme along with updated version that is available. Click the check box besides the theme screenshot and click “Update Theme” button.
Method 2

You can also navigate to
Dashboard >> Appearance >> Theme
Here you will see the notification labeled “New Version Available ‘Update Now'”. Click on the Update Now link and it will update the theme to the newer version.
