Why create a custom Magento 2 theme?

There are a number of reasons why you may want to create or customize a Magento 2 theme:

• The first and most obvious reason to customize your Magento 2 theme is that this can help you to distinguish your store from your competitors.
• Customizing your Magento 2 theme can also allow you to better integrate extensions from Magento Connect into your store, with additional features.
• If you have an existing website and wish to add e-commerce by integrating Magento 2 around the existing system, theming Magento 2 can make sure that there is visually seamless integration between the two systems.
• Theming Magento 2 can also be useful in order to customize your store to reflect the different expectations of your customers from around the world. For example, customers in some countries may expect components of your store to appear in one location on their screen, so you could theme Magento 2 to reflect this if your customers are primarily from that country.
