+# Calculator
+
+A calculator repl.
+
+## Features
+
+- Arithmetic
+- Standard mathematical functions
+- Variable bindings
+- Function bindings
+  - Single argument functions
+  - Multiple argument functions
+- Plotting (Optional)
+  - Static plots (no animation)
+  - Dynamic plots (for multiple argument functions)
+
+## Installation and plotting support
+
+The plotting support is optional as it requires `gtk2hs`. It is off by default, and can be turned on using a configuration as shown.
+
+To install *without* plotting support.
+
+```bash
+$ cabal install calculator
+```
+
+To install *with* plotting support.
+
+```bash
+$ cabal install calculator --flags="plot-gtk-ui"
+```
+
+## TODO
+
+    Lots and lots of testing.
+
+## Implementation
+
+* Written in haskell
+* Parsing done using [parsec](https://hackage.haskell.org/package/parsec)
+* Repl built using [haskeline](https://hackage.haskell.org/package/haskeline)
+* Colored output using ANSI color codes
+
+## Usage
+
+    Use :? to view usage instructions.
+
+## Thanks
+
+* Thanks to [husky](https://github.com/markusle/husky) for color output.
