 Assets are stored in `registrar/assets` during development and served from `registrar/public`. During deployment, assets are copied from `registrar/assets` into `registrar/public`. Any assets which need processing, such as USWDS Sass files, are processed before copying.
 
+**Note:** Custom images are added to `/registrar/assets/img/registrar`, keeping them separate from the images copied over by USWDS. However, because the `/img/` directory is listed in `.gitignore`, any files added to `/registrar/assets/img/registrar` will need to be force added (i.e. `git add --force <img-file>`) before they can be deployed.

 We utilize the [uswds-compile tool](https://designsystem.digital.gov/documentation/getting-started/developers/phase-two-compile/) from USWDS to compile and package USWDS assets.
