@@ -82,9 +82,9 @@ Common keyword arguments for regular and parallel sampling are:
     The common keyword arguments `progress`, `chain_type`, and `callback` are not supported by the iterator [`AbstractMCMC.steps`](@ref) and the transducer [`AbstractMCMC.Sample`](@ref).
 
 There is no "official" way for providing initial parameter values yet.
-However, multiple packages such as [EllipticalSliceSampling.jl](https://github.com/TuringLang/EllipticalSliceSampling.jl) and [AdvancedMH.jl](https://github.com/TuringLang/AdvancedMH.jl) support an `init_params` keyword argument for setting the initial values when sampling a single chain.
-To ensure that sampling multiple chains "just works" when sampling of a single chain is implemented, [we decided to support `init_params` in the default implementations of the ensemble methods](https://github.com/TuringLang/AbstractMCMC.jl/pull/94):
-- `init_params` (default: `nothing`): if `init_params isa AbstractArray`, then the `i`th element of `init_params` is used as initial parameters of the `i`th chain. If one wants to use the same initial parameters `x` for every chain, one can specify e.g. `init_params = FillArrays.Fill(x, N)`.
