+# Instructions
+
+Convert a phrase to its acronym.
+
+Techies love their TLA (Three Letter Acronyms)!
+
+Help generate some jargon by writing a program that converts a long name like Portable Network Graphics to its acronym (PNG).
+
+Punctuation is handled as follows: hyphens are word separators (like whitespace); all other punctuation can be removed from the input.
+
+For example:
+
+|Input|Output|
+|-|-|
+|As Soon As Possible|ASAP|
+|Liquid-crystal display|LCD|
+|Thank George It's Friday!|TGIF|
