+# filmoteca
+
+1. Read doc/filmoteca.pdf
+2. Create a file tree just like the one described
+3. Run `filmoteca -d /your/filmoteca -a /your/assets -p 8080'
+4. Enjoy
+
+# Styling
+
+This is what the `-a assetsdir' option is for, you can put a
+`style.css' and a `favicon.ico' for the filmoteca to send, usually to
+web browser clients.
+
+# BUGS
+
+Any problems, errors, misbehavior you might find, please contact the
+author.
