 ## Forms
 
 All assertables macros have forms for different outcomes:
 
-* `[assert_gt!(a, b);](https://docs.rs/assertables/8.17.0/assertables/macro.assert_gt.html) // panic during typical test`
-* `[assert_gt_as_result!(a, b);](https://docs.rs/assertables/8.17.0/assertables/macro.assert_gt_as_result.html) // return Ok or Err`
-* `[debug_assert_gt!(a, b);](https://docs.rs/assertables/8.17.0/assertables/macro.debug_assert_gt.html) // panic when in debug mode`
+* [`assert_gt!(a, b);`](https://docs.rs/assertables/8.18.0/assertables/macro.assert_gt.html) `// panic during typical test`
+* [`assert_gt_as_result!(a, b);`](https://docs.rs/assertables/8.18.0/assertables/macro.assert_gt_as_result.html) `// return Ok or Err`
+* [`debug_assert_gt!(a, b);`](https://docs.rs/assertables/8.18.0/assertables/macro.debug_assert_gt.html) `// panic when in debug mode`
 
 All assertables macros have forms for an optional message:
 
-* `[assert_gt!(a, b);](https://docs.rs/assertables/8.17.0/assertables/macro.assert_gt.html) // automatic error message`
-* `[assert_gt!(a, b, "your text");](https://docs.rs/assertables/8.17.0/assertables/macro.assert_gt.html) // custom error message`
+* [`assert_gt!(a, b);`](https://docs.rs/assertables/8.18.0/assertables/macro.assert_gt.html) `// automatic error message`
+* [`assert_gt!(a, b, "your text");`](https://docs.rs/assertables/8.18.0/assertables/macro.assert_gt.html) `// custom error message`
 
 Many assertables macros have forms for comparing left hand side (LHS) and right hand side (RHS) as the same type or as an arbitrary expression:
 
-* `[assert_ok_eq!(a, b);](https://docs.rs/assertables/8.17.0/assertables/macro.assert_ok_eq.html) // Ok(…) = Ok(…)`
-* `[assert_ok_eq_expr!(a, b);](https://docs.rs/assertables/8.17.0/assertables/macro.assert_ok_eq_expr.html) // Ok(…) = expression`
+* [`assert_ok_eq!(a, b);`](https://docs.rs/assertables/8.18.0/assertables/macro.assert_ok_eq.html) `// Ok(…) = Ok(…)`
+* [`assert_ok_eq_expr!(a, b);`](https://docs.rs/assertables/8.18.0/assertables/macro.assert_ok_eq_expr.html) `// Ok(…) = expression`
