 By default, hindent preserves the newline or lack of newline in your input. With `force-trailing-newline`, it will make sure there is always a trailing newline.
 
-hindent can be forced to insert a newline before specific operators and tokens with `line-breaks`. This is especially useful when utilizing libraries like [`servant`](https://www.servant.dev/) which use long type aliases.
+hindent can be forced to insert a newline before specific operators and tokens with `line-breaks`. This is especially useful when utilizing libraries like [`servant`](https://docs.servant.dev/) which use long type aliases.
 
 Using `extensions`, hindent can be made aware of valid syntactic compiler extensions that would normally be considered invalid syntax.
