 # Writing an Interpreter in Go
 
 This repo is my journey going through the book [Writing an Intrpreter in Go](https://interpreterbook.com/) by Thorsten Ball.
+
+## How To Run the Code?
+
+The interpreter is just a "REPL" (Read, Evaluate, Print, Loop) and is meant to be used
+interactively like so:
+
+```console
+$ go run main.go
+Hello michohl! This is the Monkey programming language!
+Feel free to type in commands
+>> let x = {"foo": "bar", "zed": "asdf"}
+>> x["zed"]
+asdf
+>>
+```
+
+## What is From the Book and What are Your Ideas?
+
+I've followed the book diligently from start to finish and did not stray at any point. Once
+completed I have created a `1.0` release to denote that everything up to that point was
+"as the author intended".
+
+Anything beyond version `1.0` can be recognized as my own ideas and implementations.
+
+## Did I Like the Book?
+
+I'm assumming if you're even looking at this repository you're researching whether or not
+the book in question is worth buying. I would say it was a worthwhile read from my perspective.
+
+The author has a very easy to read style of writing that I appreciated and I enjoy the learning
+style of having your hand held while going on a very verbose tour of a code base. The twist
+being that instead of just looking at ane existing code base you're creating it from scratch.
+
+I would note that part of why I found the verboseness tolerable was because I downloaded a copy
+of the repo that the author instructs you to download for reference. This allowed me to copy
+and paste the _lengthy_ test suite in as needed and spend more focus on the actual code that
+mattered.
+
+I personally hand typed the first few tests to get an idea of the methodology then
+once I felt I was bored by it I started copying and pasting.
