+Welcome to the third #code4bytes challenge!
+We find ourselves in the city of Rome, you are working as a historian in a museum and are tasked with converting roman numerals (I, V, X,...) to arabic numerals (1,2,3,4,5,...). For your convenience, an intern has typed in all the roman numerals into a text file (`roman_numerals.txt`) separated by commas. Your boss asked you to manually convert them but fortunately enough you've been hanging around in the *CodingWeb* server where you met some good people who taught you a thing or two about coding, so you think you can automate this boring task!
+```
+Read the roman numerals from roman_numerals.txt and convert them into arabic numerals.
+What is the total sum of those arabic numerals?
+
+Example:
+I, II, III, IV, V
+
+1 + 2 + 3 + 4 + 5 = 15
+```
+This challenge is quite a bit easier than the previous ones. Because of this, the first place shal recieve 500 bytes, second place 400, thrid 300 and everybody else 200. 
+
+Have fun, good luck and happy coding!
