Description
People with different level of knowlege are trying to use it. Please, make README a little more friendly. Now, Installation section of README.md makes illusion of the package as self contained. Please clearly specify dependency on C compiler. An extra line would help to avoid "surprises" and direct people to read FAQ. Here it how this note may look like.
Minimum requirements are Go 1.1+ with CGO enabled and GCC/MinGW C compiler. See "compile" section in FAQ.
Compilation on windows deserves its own section in FAQ. Take a look at Google's sqlite3 package as an example of documenting package dependencies. Short, clear and sets users aware of an extra step.
Windows users should install mingw-w64 (http://mingw-w64.sourceforge.net/), TDM64-GCC (http://tdm-gcc.tdragon.net/), or another MinGW distribution, and make sure that gcc.exe is available from the %PATH%. MSYS is not required.
Thank you for the great package!
