I'm building a lightning component and want to style it using the SLDS.
The relevant Trailhead Module recommends that you download the SLDS and install it as a static resource.
So do the answers to these questions:
However, the SLDS lightning page clearly indicates that this is no longer necessary:
The Lightning Design System is ready to use in your Lightning apps and components. It is now automatically included for Lightning Components running in the Lightning Experience and Salesforce S1 mobile application. It is no longer necessary to add a static resource for Lightning Components running within these environments.
Can I use SLDS without downloading it as a local resource? If so, is there an up-to-date tutorial on how to do this? Alternatively, can anybody give me some pointers on how to do this?
