+By default, precompilation is disabled, but can be enabled for "tensors" of type `Array{T,N}`, where `T` and `N` range over the following values:
 
 * `T` is either `Float64` or `ComplexF64`
 * `tensoradd!` is precompiled up to `N = 5`
 * `tensortrace!` is precompiled up to `4` free output indices and `2` pairs of traced indices
 * `tensorcontract!` is precompiled up to `3` free output indices on both inputs, and `2` contracted indices
 
-## Custom settings
+To enable precompilation with these default settings, you can *locally* change the `"precompile_workload"` key in the preferences.
+
+```julia
+using TensorOperations, Preferences
+set_preferences!(TensorOperations, "precompile_workload" => true; force=true)
+```
 
-The default precompilation settings can be tweaked to allow for more or less expansive coverage. This is achieved
-through a combination of `PrecompileTools`- and `Preferences`-based functionality.

+Here **setting** and **value** can take on the following:
 
 * `"precomple_eltypes"`: a `Vector{String}` that evaluate to the desired values of `T<:Number`
 * `"precompile_add_ndims"`: an `Int` to specify the maximum `N` for `tensoradd!`
