Hi. I'm new to programming, and of course to wolfram language. I can only find documentation, instructions, and tutorials on wolfram language, nowhere can I find an access point to the programming environment or a download. Is this because it is unavailable for now or have I missed something? It is wonderful to have all these instructions but I'd really like to try some of these things out in the programming environment. 

Thanks and my apologies if this has already been addressed somewhere I could not see
