Load the spacecraft you built in the previous tutorial.
Mount on a suitable launch vehicle, enclosing in a payload fairing if you like.
Launch into orbit.
Use the upper stage to burn to Kerbin escape. Planetary solar sailing is more difficult, and isn’t well supported by the plugin yet. Time warp until you are in orbit around the sun.
Complete all staging, getting rid of the upper rocket stage.
Right click on the sail and click the “Deploy” button. Click again to stow the sail.
Right click on the control module and click “Show Navigator Controls” to show the controls window.
