-Heftia can simply be described as a higher-order version of freer-simple.
+Heftia can simply be described as a higher-order version of `freer-simple`.
 This is indeed true in terms of its internal mechanisms as well.
 
 Additionally, this library provides a consistent algebraic effects semantics that is independent of carriers and effects.

 * It is generally recommended to use effects defined with automatic derivation provided by [data-effects-th](https://hackage.haskell.org/package/data-effects-th).
