+Usage
+=====
+
+Copy the `mfm` folder into your `libsigrokdecocde/decoders` or `libsigrokdecode4DSL/decoders`
+folder. You should then find the decoder in your normal decoders list.

+
+* Read data - the actual data being read from the drive
+* Extra pulses - a channel of extra pulses to include in the data
+* Suppression - a channel that suppresses (gates) processing of the information.
