+## Introductions
 
 The traditional method of providing web interfaces to Go programs is via a built-in web server. Wails offers a different
 approach: it provides the ability to wrap both Go code and a web frontend into a single binary. Tools are provided to
 make this easy for you by handling project creation, compilation and bundling. All you have to do is get creative!
