 ## Summary
 
-This API interface's client requires the SDK, which depends on
-frequenz-api-common in the version range of 0.3.0 to < 0.4.0. However,
-electricity_trading.proto needs some proto files from frequenz-api-common,
-which are only available from version 0.5.0. This discrepancy creates
-a dependency conflict. To resolve this, the current PR incorporates
-the required protos directly from the frequenz-api-common repository and
-stores them locally. This approach eliminates the dependency on the common
-repository for the time being, until the SDK is updated to a newer version
-of frequenz-api-common.
-
-A couple of additions were also made to the `__init__` and  `_types.py` files.
