 /// Device handler implementation for the IMS-100 Imager used on the OPS-SAT mission.
 ///
+/// from the [OPSSAT Experimenter Wiki](https://opssat1.esoc.esa.int/projects/experimenter-information/wiki/Camera_Introduction):
+/// OPS-SAT has a BST IMS-100 Imager onboard for image acquisition. These RGGB images are 2048x1944px in size.
+///
+/// There are two ways of taking pictures, with the NMF or by using the camera API directly.
+///
+/// As the NMF method is already explained in the NMF documentation we will focus on triggering the camera API.
+///
+/// The camera is located on the -Z face of OPS-SAT
+///
+/// Mapping between camera and satellite frames:
+/// cam body
+/// +x -z
+/// +y -x
+/// +z +y
+///
+/// If you look onto Flatsat as in your picture coordinate system for camera it is
+///
+/// Z              Z pointing inside Flatsat
+///  x---> X
+/// |
+/// |
+///  v Y
