@@ -17,5 +17,20 @@ Here's a simple program to move a file from the current directory:
     file="`ls | ask "Pick a file: "`"
     mv "$file" "`ask "Move $file to: "`"
 
+`ask` also supports a few other command line options:
+
+* `ask -y` or `ask --yes` and `ask -n` or `ask --no` will append " [Y/n]" or
+  " [y/N]" respectively to the prompt, and provide "Y" and "N" as the only
+  options, and will exit with success or failure accordingly. (e.g. `if ask
+  --yes "Continue?"; then ...`)
+* `ask --quickpick` or `ask -Q` will pick an option automatically without
+  pressing enter if there is only one valid option.
+* `ask --password` or `ask -P` will show a typing indicator without displaying
+  the typed letters on the screen. (e.g. `password="$(ask -P "Enter your
+  password: ")"`)
+* `ask --history=<name>` will load/save previous `ask` responses in
+  `$XDG_DATA/ask/<name>.hist` (`~/.local/share/ask/<name>.hist` by default) for
+  use with up/down arrow keys. Maximum of 1000 entries are stored per log file.
