 #      Maybe you will want to add more hooks for receiving messages, so i've made following script
 #      - It just executes all +x files in answerscripts.d directory so you should do your magic there
-#      - To disable some of those scripts just use chmod -x script
+#      - To disable some of those scripts simply use: chmod -x ./script
+#      - There is some basic structure, which means that all scripts should start their names with two-digit number
+#      - Files are executed in order specified by those numbers and some numbers have special meanings:
+#              - AB?!_ scripts without numbers are NOT executed!
+#              - 00    executed immediately, zero or single line output (parallel async processing)
+#              - 01-48 executed immediately, multiline output (serial processing)
