 As ChefTap cannot import these files anyway there won't be an exporter implemented in Tandoor.
 
+## MealMaster
+Meal master can be imported by uploading one or more meal master files. 
+The files should either be `.txt`, `.MMF` or `.MM` files. 
+
+The MealMaster spec allow for many variations. Currently, only the on column format for ingredients is supported.
+Second line notes to ingredients are currently also not imported as a note but simply put into the instructions.
+If you have MealMaster recipes that cannot be imported feel free to raise an issue.
+
 ## RezKonv
 The RezKonv format is primarily used in the german recipe manager RezKonv Suite. 
 To migrate from RezKonv Suite to Tandoor select `Export > Gesamtes Kochbuch exportieren` (the last option in the export menu).
 The generated file can simply be imported into Tandoor.
+
+As i only had limited sample data feel free to open an issue if your RezKonv export cannot be imported.
