Severity:

Very Low - Translation or documentation mistake. Something that won't give anyone a bad day.

Description:

The BROWSERS.md doc links to a non-existent doc which causes an error from GitHub, more specifically it's the preload link within the phrase "Preload content on the fly using preload feature", the link should be:

https://github.com/ipfs/js-ipfs/blob/master/docs/MODULE.md#optionspreload

But, it's currently:

https://github.com/ipfs/js-ipfs/blob/master/packages/ipfs/docs/MODULE.md#optionspreload

Also, DELEGATE_ROUTERS.md links to itself when trying to specify the libp2p option, it's should be:

https://github.com/ipfs/js-ipfs/blob/master/docs/MODULE.md#optionslibp2p

But, it's currently:

https://github.com/ipfs/js-ipfs/blob/master/docs/DELEGATE_ROUTERS.md#optionslibp2p

Thank you @LynHyper ! I fixed them in #4043.
In the future do not hesitate and open a PR yourself (same amount of work as describing what needs to be fixed)
