  1. # Configuration
  2. Tendermint Core can be configured via a TOML file in
  3. `$TMHOME/config/config.toml`. Some of these parameters can be overridden by
  4. command-line flags. For most users, the options in the `##### main base configuration options #####` are intended to be modified while
  5. config options further below are intended for advance power users.
  6. ## Options
  7. The default configuration file create by `tendermint init` has all
  8. the parameters set with their default values. It will look something
  9. like the file below, however, double check by inspecting the
  10. `config.toml` created with your version of `tendermint` installed:
