+## W2Julia - Conversion to Julia structures
+W2Julia is designed primarily to convert wolfram structures to Julia structures. This includes conversions of Mathematica lists to Julia vectors and Mathematica associations to Julia dictionaries.
+
+Some examples or tests that will evaluate to true:
+
+```
+using Test
+@test W2Julia(W`{1,2,3}`) == [1,2,3]
+@test W2Julia([1,2,3]) == [1,2,3]
+@test W2Julia(W`{1,2,3}`) == [1,2,3]
+@test W2Julia(W`{1,a,{1,2}}`) == [1,W"a",[1,2]]
+@test W2Julia([.1,W`{1,a,3}`]) == [.1,[1,W"a",3]]
+
+@test W2Julia(Dict( 1 => "A" , "B" => 2)) ==Dict( 1 => "A" , "B" => 2)
+
+@test W2Julia(W`Association["A" -> "B", "C" -> "D"]`) == Dict( "A" => "B" , "C" => "D")
+
+@test W2Julia(W`Association["A" -> {1,a,3}, "B" -> "C"]`) == Dict( "A" => [1,W"a",3] , "B" => "C")
+```
+
+W2Julia does not convert expressions to Julia functions, as not all functions will be able to evaluate when WSymbols are present.

 Printing in Jupyter notebooks is, by default, done in latex.
 This can be turned off with the command `MathLink.set_texOutput(false)`
