• Fixed your profile photo in the credits
• Formatted README (incl. table)

Someone is attempting to deploy a commit to a Personal Account owned by @Xyphyn on Vercel.

@Xyphyn first needs to authorize it.

Thanks! Is there a neat way to explain that lemdroid is an instance that uses photon as the default rather than it just being a photon instance?
It'd also probably be good to add the nginx config to fix that error to the docs (and maybe add a warning at the top of the readme)

[CorvetteCole]

imo, the fact that the link points to the base domain is a reliable indicator of this. do agree with the nginx thing, will add soon

lemdro.id doesn't allow setting custom instance and README.md states that "this is for general purpose Photon instances". It should be excluded.
