 This is supported via the following syntax:
 
-```jldoctest; output=false
+```jldoctest
 g = 1.0
 L = 16
 H = transverse_field_ising(; g)
 ψ₀ = FiniteMPS(L, ComplexSpace(2), ComplexSpace(32))
 ψ, envs, = find_groundstate(ψ₀, H; verbosity=0)
 E₀ = real(sum(expectation_value(ψ, H, envs)))
 Es, ϕs = excitations(H, ChepigaAnsatz(), ψ, envs; num=1)

 In order to improve the accuracy, a two-site version also exists, which varies two neighbouring sites:
 
-```jldoctest; output=false
+```jldoctest
 g = 1.0
 L = 16
 H = transverse_field_ising(; g)
 ψ₀ = FiniteMPS(L, ComplexSpace(2), ComplexSpace(32))
 ψ, envs, = find_groundstate(ψ₀, H; verbosity=0)
 E₀ = real(sum(expectation_value(ψ, H, envs)))
 Es, ϕs = excitations(H, ChepigaAnsatz2(), ψ, envs; num=1)
-@show Es
-
+E₀, Es
 ```
 
 The algorithm is described in more detail in the following paper:
