# Publishing Local Mode API Instances

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

For Flex Gateway running in Local Mode, you publish API instances using
[local declarative configuration files](https://docs.mulesoft.com/gateway/1.12/flex-local-configuration-reference-guide). You specify the
location of these configuration files when you first run Flex Gateway.

For more information about how to run the gateway, see
[Registering and Running Flex Gateway in Local Mode](https://docs.mulesoft.com/gateway/1.12/flex-local-reg-run).

Refer to these tutorials for examples on publishing APIs in Local Mode:
