 StaticWeb
 =========
 
-StaticWeb
\ No newline at end of file
+StaticWeb is a basic static files web server written in Go.
+
+It automatically serves the content of the folder corresponding to the domain of the website.
+
+Usage
+-----
+
+``./StaticWeb -addr="[Address to listen: 127.0.0.1]" -port="[Port to listen: 80]" -dir="[Absolute or relative path to the root directory to serve: .]" -log="[Absolute or relative path to the log file. Leave empty for stdout]"``
+
+The program will serve the files in the folder (inside the given root directory) with the same name as the domain from which the request originated.
+
+To serve multiple sites with the same content, you can use symbolic links.
