 We currently recommend C# for developing smart contracts. The Java compiler is still in development but the current version (neoj) can handle basic methods.

 1. Download Neo's Node GUI. At the time of writing, it is recommended you use the BETA developer GUI as it has some extra debugging features which are helpful.

 3. Download an IDE for Java (optional but recommended), e.g. IntelliJ or Eclipse.
 4. Download an IDE for C# - currently the neoj compiler needs to be built manually as it is not in wide distribution release format. Recommended is to get Visual Studio 2017 which is free.
