# Create a market group (or rename the group its name maps to)

> Creates a group whose id is derived from `name` (lowercased, spaces and dashes to underscores) and moves the given markets into it. A name that maps to an existing id renames that group instead. Writes config.market_group and config.market; returns the group.
