 Nabla.jl is a reverse-mode automatic differentiation package targetting machine learning use cases. 
 As such, we have (for example) prioritised support for linear algebra optimisations and higher-order functions over the ability to take higher-order derivatives (Nabla currently only supports first-order derivatives).
 
-Nabla is currently under active development and improved documentation will be made available soon. 
-Until then, the code in the [examples](examples) folder best indicates how to use the package. 
+The [latest docs](https://invenia.github.io/Nabla.jl/latest/), and code in the [examples](examples) folder, best indicate how to use the package. 
 Given the early stage of development, we anticipate a number of bugs and performance issues. 
 If you encounter any of these or have any particular feature requests, please raise an issue and let us know.
