+# Day 1: Trebuchet?!
+
+Something is wrong with global snow production, and you've been selected to take a look. 
+The Elves have even given you a map; on it, they've used stars to mark the top fifty 
+locations that are likely to be having problems.
+
+You've been doing this long enough to know that to restore snow operations, you need to 
+check all *fifty stars* by December 25th.
+
+Collect stars by solving puzzles. Two puzzles will be made available on each day in 
+the Advent calendar; the second puzzle is unlocked when you complete the first. Each 
+puzzle grants *one star*. Good luck!
+
+You try to ask why they can't just use a weather machine ("not powerful enough") and where 
+they're even sending you ("the sky") and why your map looks mostly blank ("you sure ask a 
+lot of questions") and hang on did you just say the sky ("of course, where do you think 
+snow comes from") when you realize that the Elves are already loading you into a 
+trebuchet ("please hold still, we need to strap you in").
+
+As they're making the final adjustments, they discover that their calibration 
+document (your puzzle input) has been **amended** by a very young Elf who was apparently 
+just excited to show off her art skills. Consequently, the Elves are having trouble 
+reading the values on the document.
+
+The newly-improved calibration document consists of lines of text; each line originally 
+contained a specific **calibration value** that the Elves now need to recover. On each line,
+the calibration value can be found by combining the **first digit** and the **last digit** 
+(in that order) to form a single **two-digit number**.
+
+For example:
+
+```
+1abc2
+pqr3stu8vwx
+a1b2c3d4e5f
+treb7uchet
+```
+
+In this example, the calibration values of these four lines are 12, 38, 15, and 77. 
+Adding these together produces 142.
+
+Consider your entire calibration document. **What is the sum of all of the calibration values?**
