 # FLIT
 
-create fluttering folders
+Create fluttering folders
 
-- flit add [days] 
-  - create folder with 30 days or specified life time
-- flit list
-  - list folders with due dates
+Basic function:
+
+- You want to share files over a web server.
+- You don't want the URL to be guessable, but also not too long to share.
+- You want the share to expire over time, and files deleted
+
+# Installation
+
+- Create a folder that is publicily visible on a web server, like Nginx.
+- Copy the flit.example as executable `flit`, and add the public URL in the 
+  script.
+- Have the flit.py in the same folder.
+- Add a symlink to flit script so that it is in the PATH, i.e. `ln -s $(pwd)/flit ~/.local/bin/flit`
+- Add `flit del` to daily cron
+
+# Usage
+
+- flit add [-d {days}] [-m {description}] [files]
+  - Create folder with 30 days or specified life time
+  - You can add *files* to be copied in the folder, or simply copy them
+    yourself.
+- flit list [-v]
+  - List folders with due dates
+  - Use the verbose switch to list URLS to all files in the shares
 - flit del
-  - delete due folders
+  - Delete due folders
+
+Note: This utility does not create indexes of files. Use another tool, or let
+web server index.
 
-hint: add  `flit del` to cron.daily
