A share code is only the start. To use it well, you need to know what the preview means, which parameters changed, and when to adjust instead of copying another code.
A reliable routine is enough: copy the code, import it, test it, adjust one value, and save it only when it still feels good after practice.
Workflow
1. Preview the code first
Use the xhair.pro preview to confirm the shape, color, dot, and outline before opening CS2.
2. Import it in CS2
Paste the share code into the in-game crosshair import screen.
3. Play a short test
Run deathmatch or an aim map for a few minutes before judging the setup.
4. Tune one parameter
Change one value at a time, such as size, gap, thickness, or color.
