  * This OpMode illustrates the basics of AprilTag recognition and pose estimation,
  * including Java Builder structures for specifying Vision parameters.
  *
+ * For an introduction to AprilTags, see the FTC-DOCS link below:
+ * https://ftc-docs.firstinspires.org/en/latest/apriltag/vision_portal/apriltag_intro/apriltag-intro.html
+ *
+ * In this sample, any visible tag ID will be detected and displayed, but only tags that are included in the default
+ * "TagLibrary" will have their position and orientation information displayed.  This default TagLibrary contains
+ * the current Season's AprilTags and a small set of "test Tags" in the high number range.
+ *
+ * When an AprilTag in the TagLibrary is detected, the SDK provides location and orientation of the tag, relative to the camera.
+ * This information is provided in the "ftcPose" member of the returned "detection", and is explained in the ftc-docs page linked below.
+ * https://ftc-docs.firstinspires.org/apriltag-detection-values
+ *
+ * To experiment with using AprilTags to navigate, try out these two driving samples:
+ * RobotAutoDriveToAprilTagOmni and RobotAutoDriveToAprilTagTank
+ *
+ * There are many "default" VisionPortal and AprilTag configuration parameters that may be overridden if desired.
+ * These default parameters are shown as comments in the code below.
+ *
  * Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
