The setup instructions at
https://github.com/conan-io/hooks#hook-activation
give the following instruction:

conan config set hooks.conan-center

However, when I try this with conan 2.0.7 (current version), it says:

conan config set hooks.conan-center
usage: conan config [-h] [-v [V]] {home,install,list,show} ...
conan config: error: argument subcommand: invalid choice: 'set' (choose from 'home', 'install', 'list', 'show')
ERROR: Exiting with code: 2

It seems that set has been removed from the list of choices.

The instructions also mention setting up a conan.conf file, but do not mention WHERE this file should be placed.

Please advise how to set up the conan hooks, which is required to be able to raise pull requests against https://github.com/conan-io/conan-center-index.
