+# Etl
+
+We are going to do the `Transform` step of an Extract-Transform-Load.
+
+### ETL
+Extract-Transform-Load (ETL) is a fancy way of saying, "We have some crufty, legacy data over in this system, and now we need it in this shiny new system over here, so
+we're going to migrate this."
+
+(Typically, this is followed by, "We're only going to need to run this
+once." That's then typically followed by much forehead slapping and
+moaning about how stupid we could possibly be.)
+
+### The goal
+We're going to extract some scrabble scores from a legacy system.
+
+The old system stored a list of letters per score:
+
+- 1 point: "A", "E", "I", "O", "U", "L", "N", "R", "S", "T",
+- 2 points: "D", "G",
+- 3 points: "B", "C", "M", "P",
+- 4 points: "F", "H", "V", "W", "Y",
+- 5 points: "K",
+- 8 points: "J", "X",
+- 10 points: "Q", "Z",
+
+The shiny new scrabble system instead stores the score per letter, which
+makes it much faster and easier to calculate the score for a word. It
+also stores the letters in lower-case regardless of the case of the
+input letters:
+
+- "a" is worth 1 point.
+- "b" is worth 3 points.
+- "c" is worth 3 points.
+- "d" is worth 2 points.
+- Etc.
+
+Your mission, should you choose to accept it, is to write a program that
+transforms the legacy data format to the shiny new format.
+
+### Notes
+
+A final note about scoring, Scrabble is played around the world in a
+variety of languages, each with its own unique scoring table. For
+example, an "E" is scored at 2 in the Māori-language version of the
+game while being scored at 4 in the Hawaiian-language version.
+
+To run the tests simply run the command `go test` in the exercise directory.
+
+If the test suite contains benchmarks, you can run these with the `-bench`
+flag:
+
+ go test -bench .
