+# Spectroscopy Amplifier (model 2020)
+
+Schrijf de handleiding voor je module hier. Kijk gerust naar de handleiding
+voor de "Doolhof"-module (`src/modules/puzzle_maze/doc/index.md`)
+
+
+Hieronder wat voorbeelden van markup die je kan gebruiken. Daarnaast kan je ook LaTeX
+gebruiken (zie bijvoorbeeld de "Doolhof"-module)
+
+Use drawings! Create the docs/images/your_module directory, put your image there and include them like this:
+
+![](./your_module/filename.png)
+
+Use tables! Write them like this:
+
+| Symbol                         | Action to take |
+|--------------------------------|----------------|
+| ![](./your_module/symbol1.png) | Do nothing     |
+| ![](./your_module/symbol2.png) | Press the red button |
+| ![](./your_module/symbol3.png) | Press the yellow button |
