I have to install emscripten to get webassembly?

[zappfinger]

On this main site http://webassembly.org/getting-started/developers-guide/, there is something didactically very wrong: It looks like in order to get webassembly I have to install emscripten. This suggests that emscripten IS webassemly. Maybe it is, but that should be explained in a few lines.

Now it is like I want to install package A, I go to the site of package A and there it says I have to install package B....
