Link works just fine for me as is

Ok so it looks like navigating by clicking links in the docs result in no trailing /, while loading a fresh page always add a trailing /. I think you guys might need to change docusaurus's trailingSlashconfig

@CelloSerenity Try going to https://docs.sidestore.io/docs/intro, click the prereq link, then click the install link

[lts20050703]

@CelloSerenity Actually no my bad that would work. What doesn't work is going to https://docs.sidestore.io/docs/installation/prerequisites, which should always add a trailing slash, then click the "Install" link

Ohhh, that makes sense and I can reproduce it. I'll look into it unless you don't mind making another PR.
