+# Forth
+
+Welcome to Forth on Exercism's Go Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+Implement an evaluator for a very simple subset of Forth.
+
+[Forth](https://en.wikipedia.org/wiki/Forth_%28programming_language%29)
+is a stack-based programming language. Implement a very basic evaluator
+for a small subset of Forth.
+
+Your evaluator has to support the following words:
+
+- `+`, `-`, `*`, `/` (integer arithmetic)
+- `DUP`, `DROP`, `SWAP`, `OVER` (stack manipulation)
+
+Your evaluator also has to support defining new words using the
+customary syntax: `: word-name definition ;`.
+
+To keep things simple the only data type you need to support is signed
+integers of at least 16 bits size.
+
+You should use the following rules for the syntax: a number is a
+sequence of one or more (ASCII) digits, a word is a sequence of one or
+more letters, digits, symbols or punctuation that is not a number.
+(Forth probably uses slightly different rules, but this is close
+enough.)
+
+Words are case-insensitive.
