# /srv/app/peppermint.json needs to be your peppermint.json file.
# IMPORTANT: Set data_storage_dir to /srv/data!
# See also https://starbeamrainbowlabs.com/labs/peppermint/peppermint-config-info.php#config_data_storage_dir
# To generate the peppermint.json file in the first place, you'll have to setup a temporary instance of Pepperminty Wiki (even just using e.g. php -S [::]:35623 -t build after cloning the git repository.)
# 
# Alternatively, you can fill peppermint.json with simply e.g. '{ "data_storage_dir": "/srv/data", "firstrun_complete": false }' (omit single quotes), and then mount that writably, and Pepperminty Wiki will fill out the rest of the missing settings.
