Setting up the client#
A client in the Tezos network provides different configuration possibilities:
tune various parameters of the client using flexible combinations of: a configuration file, command-line options, and environment variables
configure how keys are managed, with different security tradeoffs
select different running modes, beside the default mode, which are intended to facilitate testing applications on smaller or fake networks: for example by executing some RPCs locally, without sending requests to a Tezos node.
These configuration possibilities are described in the following pages.
