Change from Basically to WooCommerce Theme

I started building my website with Basically and it was a good place to start considering my lack of experience and knowledge of building a WordPress website. However, I have learned that as good as Basically is, it does not meet my needs for ecommerce, i.e. I have a small business where I sell wood art products. Woocommerce has a free theme ‘mystile’ and I have read good reviews about the theme for small businesses.

How do I change from Basically theme to the Woocommerce theme mystile? Is it as simple as uninstall Basically and install mystile?

Thanks
