GitHub Language Detection for IAR Embedded Workbench Assembly (.asm) Files

[CamilaDziubat]

I'm working with IAR Embedded Workbench and writing Assembly code in .asm files for microcontroller projects. However, when I push my repository to GitHub, the language is not detected as Assembly. I want to understand how GitHub detects Assembly language files and what I might be missing.

Specifically:

How does GitHub identify Assembly files from IAR projects?

Are there recommended file extensions or configurations to ensure proper language detection?

Can using a .gitattributes file help GitHub classify .asm files correctly?

Any insights or suggestions would be greatly appreciated.
