# slack-cli must be configured using the SLACK_CLI_TOKEN environment variable.
# Using `slack init` will not work because it tries to write to the Nix store.
#
# There is no reason that we couldn't change the file path that slack-cli uses
# for token storage, except that it would make the Nix package inconsistent with
# upstream and other distributions.
