+
+A low-overhead implementation of Newton-Raphson. This method is non-allocating on scalar
+and static array problems.
+
+!!! note
+
+    As part of the decreased overhead, this method omits some of the higher level error
+    catching of the other methods. Thus to see better error messages, use one of the other
+    methods like `NewtonRaphson`
+
+### Keyword Arguments
+
+- `chunk_size`: the chunk size used by the internal ForwardDiff.jl automatic differentiation
+  system. This allows for multiple derivative columns to be computed simultaniously,
+  improving performance. Defaults to `0`, which is equivalent to using ForwardDiff.jl's
+  default chunk size mechanism. For more details, see the documentation for
+  [ForwardDiff.jl](https://juliadiff.org/ForwardDiff.jl/stable/).
+- `autodiff`: whether to use forward-mode automatic differentiation for the Jacobian.
+  Note that this argument is ignored if an analytical Jacobian is passed as that will be
+  used instead. Defaults to `Val{true}`, which means ForwardDiff.jl is used by default.
+  If `Val{false}`, then FiniteDiff.jl is used for finite differencing.
+- `diff_type`: the type of finite differencing used if `autodiff = false`. Defaults to
+  `Val{:forward}` for forward finite differences. For more details on the choices, see the
+  [FiniteDiff.jl](https://github.com/JuliaDiff/FiniteDiff.jl) documentation.
