    **Note:** Do not download LogCLI or Loki Canary at this time. [LogCLI](../../getting-started/logcli/) allows you to run Loki queries in a command line interface. [Loki Canary](../../operations/loki-canary/) is a tool to audit Loki performance.
 4. Unzip the package contents into the same directory. This is where the two programs will run.
 5. In the command line, change directory (`cd` on most systems) to the directory with Loki and Promtail. Copy and paste the commands below into your command line to download generic configuration files.
