Configuration

The configuration must be set in a sigal.conf.py file in the current directory. It can also be specified with the -c flag. An example file with explanations on the settings is available in sigal/templates/sigal.conf.py and is shown below. This file is copied to the current directory with the sigal init commmand.

# All configuration values have a default; values that are commented out serve
# to show the default. Default values are specified when modified in this
# example config file

# Gallery title. Can be set here or as the '--title' option of the `sigal
# build` command, or in the 'index.md' file of the source directory.
# The priority order is: cli option > settings file > index.md file
