+## Non-Interactive Mode
+
+The Gemini CLI can be run in a non-interactive mode, which is useful for scripting and automation. In this mode, you can pipe input to the CLI and it will execute the command and exit.

+To use the non-interactive mode, you can pipe a command to the CLI. For example:
+
+```bash
+echo "What is fine tuning?" | gemini
+```
+
+You can achieve the same result with the `--prompt` or `p` argument. For example:
+
+```bash
+gemini -p "What is fine tuning?"
+```
+
+In both cases this will execute the command and print the output to the console.
