 ## Introduction
-MY-BASIC is a tiny cross-platform easy extendable BASIC interpreter written
-in pure C with about 5000 lines of source code. Its grammar is similar
-to structured BASIC in early era, but without line number. It is aimed to
-be either an embeddable scripting language or a standalone interpreter. The
-core is pretty light; all in a C source file and an associated header file.
-You can combine MY-BASIC with an existing C / C++ / Objective-C project
-easily, that can make them more powerful.
+MY-BASIC is a tiny cross-platform easy extendable BASIC interpreter written in pure C with about 6000 lines of source code. Its grammar is similar to structured BASIC in early era, but without line number. It is aimed to be either an embeddable scripting language or a standalone interpreter. The core is pretty light; all in a C source file and an associated header file. You can combine MY-BASIC with an existing C/C++/Objective-C project easily, scripting driven can make your projects more powerful, elegant and neat.

+## Installation
 
+### Use standalone interpreter binary
+This repository contains precompiled binaries for [Win32](output/my_basic.exe) and [MacOS](output/my_basic_mac), it's efficient to download it and have a first impressive playground.
+
+To compile an interpreter binary for your own platform, please see the steps as follow.
+* Retrieve `core` and `shell` folders
+* Setup your compile context
+* Use your compiler to process `core/my_basic.c` and `shell/main.c`
+
+### Combine with exist projects
+MY-BASIC is cleanly writen in a single C source file and an associated header file. Just copy `my_basic.c` and `my_basic.h` to your project folder and add them to a build configuration.
+
+For more details about using MY-BASIC with exist projects, please see [MY-BASIC Quick Reference](MY-BASIC%20Quick%20Reference.pdf).
