Shouldn't it be a dev dependency?

[RemyMachado]

The readme.md indicates yarn add next-sitemap, but shouldn't it be installed as a dev dependency? If not, why?

@RemyMachado It's totally fine to install next-sitemap as dev dependency if you're only using it to generate static sitemaps.

However, a lot of people were using it for server sitemap generation. The initial documentations suggested to install it as dev dep, however users were having internal server issues after deployment because a lot of hosted services were only installing dependencies (production mode).

So, I changed the documentation to make it as a main dependency. But, you're totally free to move it to dev dep if your use case is only static sitemap generation.
