I am quite new to minecraft modding so I need help trying to build the mod because it requires sodium.pom or something along those lines.

Why do you need to build the mod? If you just want to use Indium, download it from Modrinth: https://modrinth.com/mod/indium

I just want to access the version of indium for sodium 0.4.11 also it's good to know for other mods aswell.

Sodium 0.4.11 and the corresponding Indium release has been taken down due to numerous issues, please downgrade to Sodium 0.4.10 (and versions of mods that support it).

Thanks for the help
