 ## Usage
 
-    ./distamp m[:s]
+    ./distamp: discord relative timestamp generator
+
+    Usage: ./distamp [-h] [-a <date>] [-d <days>] [-w <weeks>] m[:s]
+
+    -h: print this help text
+    -a <date>: Absolute date (this option is exclusive, any other options will be ignored)
+    -d <days>: Number of days
+    -w <weeks>: Number of weeks
 
     Where m is number of minutes from now and s is number of seconds from now
 
+## Config
+
+A DOS-style INI format configuration can be created at XDG\_CONFIG\_HOME/distamp/config.ini. Quoted values are not supported.
+
+The current supported keys are:
+
+    tz: the value must be a valid timezone (i.e. tz=Europe/Paris). This is used to calculate the proper locality of the date when using the -a flag.
+
