+# NimFunge98 : a Funge-98 interpreter written in nim
+
+This repository contains code for a nim program that can interpret a valid [Funge-98](https://github.com/catseye/Funge-98/blob/master/doc/funge98.markdown) program. It will soon pass the [mycology test suite](https://github.com/Deewiant/Mycology).
+
+Current limitations are :
+- it is not finished!
+- currently does not implement any fingerprints
+- does not implement concurrent execution with the `t` command
+- does not implement file I/O with the `i` and `o` commands
+- does not implement system execution with the `=` command

+
+## Dependencies
+
+nim is required. Only nim version >= 1.4.8 on linux amd64 (Gentoo) is being regularly tested.
+
+## Quick Install
+
+To install, clone this repository then run :
+```
+nimble install
+```
+
+## Usage
+
+Launching the interpreter is as simple as :
+```
+nimfunge98 -f something.b98
+```
+
+The interpreter will then load and execute the specified Funge-98 program until the program normally terminates or is interrupted or killed.
+
