This is my kobopatch.yml file.

out: out/KoboRoot.tgz
log: out/log.txt

patchFormat: kobopatch

patches:
  src/nickel.yaml: usr/local/Kobo/nickel
  src/libadobe.so.yaml: usr/local/Kobo/libadobe.so
  src/libnickel.so.1.0.0.yaml: usr/local/Kobo/libnickel.so.1.0.0

## You can put lines in the following section to override the enabled state of patches.
## The indentation matters! Each override should be indented by 4 spaces. Add to the 
## section below. This section can be copy and pasted into newer patch versions to
## keep your selections.
##
## Example of how it should look:
## overrides:
##   src/nickel.yaml:
##     Custom synopsis/details line spacing: yes
##     Whatever the yaml is called: no
##   src/libadobe.so.yaml:
##     You get the idea: yes
overrides:
  src/nickel.yaml:
  src/libadobe.so.yaml:
  src/libnickel.so.1.0.0.yaml:
  src/librmsdk.so.1.0.0.yaml:

  src/sickel.yaml:
    sickel reboot timeout (20 sec): no
    sickel reboot timeout (30 sec): yes

## TRANSLATIONS ##
# Optional, use only if lrelease is not in PATH and if translations are needed
# lrelease: /path/to/lrelease

# Uncomment the following to add translations (replace lc with the language code)
# translations:
#   src/whatever.ts: usr/local/Kobo/translations/trans_lc.qm

## ADDITIONAL FILES ##
# Uncomment the following to add additional files to the tgz (like init scripts or hyphen dicts)
# The files will be root-owned, and world readable, writable, and executable (0777)
# files:
#   src/whatever.txt: usr/local/Kobo/whatever.txt
#   src/whateverToPutInMultiplePlaces.txt:
#     - usr/local/Kobo/location1.txt
#     - usr/local/Kobo/location2.txt
files:
  src/hyphenDicts/hyph_en.dic: usr/local/Kobo/hyphenDicts/hyph_en.dic

In the src directory, I put the dictionary and the last line shows the code. You have to know where the file(s) go on the Kobo to do this.
