 ## Introduction
 
-MY-BASIC is a lightweight BASIC interpreter written in standard C in dual files. It's aimed to be embeddable, extendable and portable. It is a dynamic typed programming language, reserves structured syntax, supports a style of [prototype-based programming](https://en.wikipedia.org/wiki/Prototype-based_programming) (OOP), also implements a functional paradigm by [lambda abstraction](https://en.wikipedia.org/wiki/Anonymous_function). The core is written in a C source file and an associated header file. It's easy to either use it as a standalone interpreter or embed it with existing projects in C, C++, Java, Objective-C, Swift, C#, etc. and totally customizable by adding your own scripting interfaces.

 This repository contains precompiled binaries for [Windows](output/my_basic.exe) and [macOS](output/my_basic_mac), the easiest way is to download to get a direct playground. Or you can make a build by:
 
-* Using the Visual Studio workspace `my_basic.sln` on Windows to build an executable
+* Using the Visual Studio solution `my_basic.sln` for Windows build
-* Using the Xcode workspace `my_basic_mac.xcodeproj` on macOS to build an executable

 The standalone interpreter supports three running modes:
 
 * Execute the binary without arguments to use the interactive mode
-	* Type "HELP" and hint Enter to get usages of it
+	* Type "HELP" and hint Enter to see usages
 * Pass a file to the binary to load and run that BASIC source code

 ### Combining with existing projects
 
-Just copy [`core/my_basic.c`](core/my_basic.c) and [`core/my_basic.h`](core/my_basic.h) to your project and add them to the build configuration. You can [link with MY-BASIC as a lib](https://github.com/paladin-t/my_basic/wiki/Linking-with-MY_BASIC) as well.
