 ## Where should I put my rules?
 
-We recommend adding custom rules to your own packages with [ChainRulesCore.jl](https://github.com/JuliaDiff/ChainRulesCore.jl), rather than adding them to ChainRules.jl.
-A few packages - currently SpecialFunctions.jl and NaNMath.jl - have rules in ChainRules.jl as a short-term measure.
+We recommend adding custom rules to your own packages with [ChainRulesCore.jl](https://github.com/JuliaDiff/ChainRulesCore.jl).
+It is good to have them in the same pacakge that defines the original function.
+This avoids type-piracy, and makes it easy to keep in-sync.
+ChainRulesCore is a very light weight dependency.
