+the Stupid Blogging System, static version
+==========================================
+
+This is the repository for the Stupid Blogging System (sbs) version 2.5+.
+
+List of features of the SBS:
+ - Post in HTML, or anything that can be converted into HTML
+ - Tags
+ - Passphrase-based content encryption (JavaScript required)
+ - Automatic table of contents and footnotes generation
+ - Generates static webpages, ready to be served with httpd
+ - Flexible templates
+ - Automatic image compression (TODO, using imagemagick)
+
+Dependencies:
+ - node.js >8.x
+ - jsdom
+ - aes-js
+ - scrypt-js
+
+Usage:
+
+In directory ``generator``::
+
+ node main.js [--force]
+
+--force:
+ ignores time stamp and force generation of all pages.
