 Bash Output Generator
+
+## Usage
+
+Anotate your script with formatting helpers by using pipe construct
+
+*Example*
+
+```
+echo "Script title" | title
+echo "Author: You"  | subtitle
+```
+
+Tasks are represented introduced by the `section` helper.
+The flow is :
+  1. Print section header
+  2. Use `output` helpers to display the output you want generated
+  3. End your call with `result`
+
+```
+echo "Task number One" | section
+ls -l		       | output
+echo "Warning"	       | output::warning
+ls /non_existent_file  |& output
+```
