i need to create client side only command, so can you tell how to do this (and update a bit outdated docs)

sorry if i missed that, but anyways i googled solution for hours and didnt find solution

Fabric API very recently got a client command API, you can see an example here: https://github.com/FabricMC/fabric/blob/1.16/fabric-command-api-v1/src/testmod/java/net/fabricmc/fabric/test/command/client/ClientCommandTest.java

The wiki page will need updating to reflect this.

wow, thanks for quick reply :)

you helped me
