New Project: HTML5 Boilerplate
The right-hand pane of the Create New Project dialog looks as follows when you choose HTML5 Boilerplate from the list in the left-hand pane.
The functionality is supported only in the Professional edition when the HTML Tools plugin is installed and enabled. The plugin is bundled with PyCharm and activated by default. If the plugin is not activated, enable it on the Plugins page of the Settings / Preferences Dialog as described in Enabling and Disabling Plugins.
