+# About goals behind JavOC project
+JavOC ***[Jav-ok]*** (Java for Open Computers) is a simple implementation of Java Virtual Machine, designed to run on machines from [OpenComputers](https://www.curseforge.com/minecraft/mc-mods/opencomputers) Minecraft mod.
+
+Language - **Lua 5.2**
+
+Project was heavily inspired by Zen1th's JVM - [lukyt](https://github.com/zenith391/lukyt).
+
+## Goals
+Since Java Virtual Machine is a colossal piece of software, main goal of the project is not to implement a "real" JVM, but to create an **educational** project to explain to everyone basics of JVM architecture by example. 
+
+It makes very important to make code and documentation very detailed, comprehensive and clear for everyone. Other aspects, such as functionality, speed, effectivness, etc. are **not** the main focus, and, if it will be required, will be sacrificed in order to meet the primary goal

+# Java class file structure by example
+As you already know from "Class File Format" document, Java classes have a relatively complex structure. And the best way to study it - compile something and see these beatiful files in the wild!
+
+For such a purpose, you can use `javac` and `javad` command line tools - official compiler and disassembler, that are included into every Java Development Kit.
+
+However, there is a much more convinient method - [javap.yawk.at](https://javap.yawk.at) website!
+
+It lets you to both compile and disassemble your Java code in one click!
+
+For the beginning, let's compile a simple class.
+
+Something like **this**:
+```java
+class Main {}
+```
