+**macabre** : (adj) _tending to produce horror in a beholder_
+
+Seriously, Just back away slowly. I'm just playing around.
+
+Are you still here? Don't you know there's a monster at the end of this book?
+
+## What have you done?
+
+Nothing, yet. It only "barely" work if we carefully redefine "barely" to "doesn't".
+
+This is an ultra experimental compiler written in Gleam to compile Gleam source code (using
+the [glance](https://hexdocs.pm/glance/) package) to Python.
+
+## Why are you doing this?
+
+I have no idea. It's fun and educational. (I'm on a role with this redefining words thing)
+
+## Usage
 
 ```sh
-gleam run -- some_file.gleam  # compile to python
+gleam run -- some_very_simple_file.gleam  # compile to python
 ```

 ### TODO
 
-- most operators and expressions aren't implemented yet
+- flesh out this list
+- most expressions aren't implemented yet
+- need to print out nice errors when glance fails to parse
+- No List or Result custom types yet
 - glance doesn't support comments
 - glance doesn't fully typecheck (e.g. `2.0 - 1.5` compiles successfully, but should be `2.0 -. 1.5`)
 - not currently generating python type hints (e.g. function arguments and return types), but gleam gives us that info so may as well use it
 - no concept of a "project", gleam.toml, downloading dependencies
 - only compiles one module at a time
-- not sure how to account for `/` on two ints.
+- eliminate all todos in source code
