# 1) Sign into https://backstage.renoise.com and download the appropriate (x86 or x86_64) version

# 2) Override the releasePath attribute to point to the location of the newly downloaded bundle.
# Note: Renoise creates an individual build for each license which screws somewhat with the
# use of functions like requireFile as the hash will be different for every user.
