Typo in Documentation

[viccch]

Hi,

I found a typo in the documentation of your project. Here are the details:

Location: doc/writing.md
Line: 262
Current Text: "add_geometry"
Suggested Correction: "set_geometry"

The typo is in the section where you describe adding an existing geometry. Correcting this will help improve the readability of the documentation.

Thank you for your attention to this matter.
