Download latest release from releases
Just execute sfs-win.exe (in Windows) or sfs-macos (in macOS) to start serving static files present in the ./www folder on the 8080 port.
If you find any conflicts running this you can configure some application aspects via running it with some parameters:
-port: You can pass by a new port different from the default 8080-folder: You can pass by a new folder different from the ./www folder
For Windows and macOS: Nothing, since there's a compiled version of the application available in the repo
For Linux: Golang 1.8+, since you'll need to compile the application (sorry, this will get fixed soon).
Run build.bat in Windows or build.sh in macOS / Linux
Golang 1.8+
