# Creating a new run

> Four steps to pick a metric and launch a fine-tuning job.

This guide walks you from a blank slate to a queued training run in four steps. Each step adds one ingredient to the run; the final step lets you review and launch.

## Create a new run

From the project's [Training runs](/luna-studio/ui/projects/training-runs-home) page, click **New run** in the top right. The run-creation flow takes over the page.
