 # SSG
 
-Static site generator written in perl.
+Minimal **S**tatic **S**ite **G**enerator written in perl. This software was
+inspired in [sw](https://github.com/jroimartin/sw), a suckless webframework.
+
+## Installation
+
+There's no installation method for now. The *ssh* and *styles.css* should be on the same
+directory, and the result directory will be there as well.
+
+## Usage
+
+ssg [switches] input-directory
+
+where switches can be:
+
+* -v  print version and exits
+* -h  print this help and exits
+* -o  set the input directory (by default site.static/)
+
+By default the output directory is *./site.static/* (on the same directory as
+this program
+
+## Generation + upload
+
+You can automate all the process creating the following script.
+
+    ./ssg -o mysite input-dir
+    rsync -avz mysite/ your.site:/path/to/www
