Render readme on the package page
All big package registries put the markdown readme of a package front and center: GitHub, npm, Visual Studio Marketplace, ...
PSGallery on the other hand only shows a very small text description and then a bunch of metadata. There is a link "See documentation for more details", but confusingly that doesn't lead to the documentation of the package, it leads to the documentation of the PSGallery in general. To get to the readme on GitHub, you usually have to click the tiny "Project Site" link on the left.
If the package contains a readme.md, that is what should be prominently rendered on the package site. Concerns over embedded content/links can be solved as shown by all the other package registries that do this.
