#### Determinate

For operations where the percentage of the operation completed can be determined, use a determinate indicator. They give users a quick sense of how long an operation will take.

#### Indeterminate

For operations where the user is asked to wait a moment while something finishes up, and it's not necessary to expose what's happening behind the scenes and how long it will take, use an indeterminate indicator.

#### Theming

Your current theme colors can be used to easily colorize your progress indicator with `md-warn` or `md-accent` colors.

#### Dark theme

This is an example of the <md-progress-circular> component, with a dark theme.
