 The powerful script language designed with a stack oriented approach for efficient execution. 
 
-## Features
-
- 1. Efficient stack-oriented execution model
- 2. Clear, easy-to-understand and elegant syntax
- 3. Rich of convenient and highly extensible commands
- 4. Dynamic and flexible data types system
-
-## Sample code
-This is a sample code to solve FizzBuzz problem in Stack programming language
-```stack
-(
-     (i) var
-     (Fizz) ()
-     i 3 mod 0 equal if
-) (fizz) var
-
-(
-     (i) var
-     (Buzz) ()
-     i 5 mod 0 equal if
-) (buzz) var

-1 101 1 range (i) (
-
-     () (msg) var
-     msg i fizz eval concat (msg) var
-     msg i buzz eval concat (msg) var
-
-     (
-         i (msg) var
-     ) ()

+$ cd Stack-Programing-Language
+$ cargo build --release
+$ cargo install --path .
+```
+
+This will install the `stack` command, which you can use to run Stack Programming Language programs.
+
+## Usage
+
+To run a Stack Programming Language program, use the `stack` command followed by the path to your program file.
+
+```bash
+$ stack path/to/your/program.stk
