General Guidelines

Use there is a list of options and the user may select multiple options, including all or none.

Behavior

If it is disabled, the cursor will indicate that the selection cannot be made.
Checkboxes require the use of a button to apply the settings once they are selected.

Content guidelines 

Use positive and active wording for checkbox labels, so that it's clear what will happen if the box is checked. Avoid negative statements such as "Don't send me more emails", which would mean that the user would have to check the box in order for something not to happen.
