+#### Entry Points (To FingerprintEnrollment)
+
+* FingerprintSettings (which launches the below intent)
+* Intent -> ".biometrics.fingerprint2.ui.enrollment.activity.FingerprintEnrollmentV2Activity")
+
+#### General Architecture
+
+The code should follow the MVVM architecture.
+
+**In addition, one activity (FingerprintEnrollmentV2Activity) should**
+
+* Control a list of fragments which correspond to enrollment steps
+* Be responsible for navigation events between fragments
+* Be responsible for navigation events to other activities if need be (
+  ConfirmDeviceCredentialActivity)
+* Be the controller of the viewmodels

+### Fingerprint Settings Enrollment
+
+#### Entry Point (For Fingerprint Settings)
+
+* [SecuritySettings] (https://cs.android.com/android/platform/superproject/+/master:packages/apps/Settings/src/com/android/settings/security/SecuritySettings.java;l=40?q=SecuritySettings)
+
+#### General Architecture
+
+The code should follow the MVVM architecture.
+
+The FingerprintSettingsV2Fragment is responsible for most of the heavy lifting. It should coordinate
+navigation events, maintain the viewmodels, and launch new activities if need be.
+
+#### Style
+
+* Please use [kfmt](https://plugins.jetbrains.com/plugin/14912-ktfmt)
