# Custom configuration for the Sphinx documentation builder.
# All configuration specific to your project should be done in this file.
#
# The file is included in the common conf.py configuration file.
# You can modify any of the settings below or add any configuration that
# is not covered by the common conf.py file.

# For the full list of built-in configuration values, see the documentation:

# Product name
project = 'Sphinx and Read the Docs'

# The title you want to display for the documentation in the sidebar.
# You might want to include a version number here.
# To not display any title, set this option to an empty string.

# The default value uses the current year as the copyright year.
#
# For static works, it is common to provide the year of first publication.
# Another option is to give the first year and the current year
# for documentation that is often changed, e.g. 2022–2023 (note the en-dash).
#
# A way to check a GitHub repo's creation date is to obtain a classic GitHub
# token with 'repo' permissions here: https://github.com/settings/tokens
# Next, use 'curl' and 'jq' to extract the date from the GitHub API's output:
#
# curl -H 'Authorization: token <TOKEN>' \
#   -H 'Accept: application/vnd.github.v3.raw' \
#   https://api.github.com/repos/canonical/<REPO> | jq '.created_at'
