 ## Difference to `cosmiconfig`
-Lilconfig does not intend to be 100% compatible with `cosmiconfig` but tries to mimic it where possible. The key differences are:
-- **no** support for yaml files out of the box(`lilconfig` attempts to parse files with no extension as JSON instead of YAML). You can still add the support for YAML files by providing a loader, see an [example](#yaml-loader) below.
-- **no** cache
