Please see the official X‑Plane Support page for help.
The X-Plane 10 manual includes a glossary that might help with learning the terminology. Here is a diagram that explains plane movement if you are having trouble configuring your joystick axes.
Keep in mind that single engine planes (such as the default Cessna) will pull left due to the turn of the propeller. If you want to start over configuring your joystick, you can remove the preferences folder (found in the Output folder) and X-Plane will behave like it is a new install.
