I started learning NestJS, by reading documentation. currently, I'm using the @nestjs/mongoose package for MongoDB. unforunatley I can't find any documentation about this package. the only docs I found is this https://docs.nestjs.com/techniques/mongodb however, it's missing lots of information, such as creating an index for the schema. where can I find additional information? how people on stack overflow know some of the answers if they are not in the documentation
edit: I mean documentation of @nestjs/mongoose
