• verify your PATH includes the location where you moved the binary
• check the binary’s file permissions (it should be executable)
• ensure you downloaded the correct binary for your system.

Configuration

greymatter is configurable via flags, environment variables, and a config file. The default path for a config file is $HOME/.config/greymatter/config.toml, but an alternative path can be specified with the --config flag or the GREYMATTER_CONFIG environment variable.
