Simply add the SEP to your ACTIVE_SEPS list in settings.py: :
ACTIVE_SEPS = ["sep-1", "sep-10", ...]Every anchor must define a stellar.toml file to describe the anchors's supported assets, any validators that are run, and other meta data. Polaris provides a default function that returns the assets supported by your server, but you'll almost certainly need to replace this default to provide more detailed information.
