-## Requester APIs
-
-The pldm requester API's are present in `src/requester` folder and they are
-intended to provide API's to interact with the desired underlying transport
-layer to send/receive pldm messages.

-works with [specific transport mechanism](https://github.com/openbmc/libmctp) &
-these are going to change in future & probably aren't appropriate to be writing
-code against.
