[racket] Need some help with planet package

Hi,
I am trying to use midi.rkt from
http://planet.racket-lang.org/package-source/clements/midi.plt/1/0/midi-read.rkt.
I did the following -

1.  sudo raco planet url clements midi.plt 1 1
2. curl -O url (the url I got form the step 1)
3. I renamed the downloaded file to midi.plt
4. sudo raco planet fileinject midi  midi.plt  1 1

After this I could see the package listed when I did raco planet show.

However I have no clue wrt the "require" I need to do in my racket file.

Regards,
Kashyap
