 # Introduction:
-SMS (Symbolic Math System) is a math-focused scripting language for POSIX friendly operating systems. SMS has built-in functions for arithmetic, trigonometry, algebra, calculus, file access and more. SMS aims to become a simple general purpose programming language. SMS is still in early stages of development. SMS can be downloaded and installed from the Releases page on GitHub. The latest source code may have undocumented changes and this document is synchronized with the project at the point of the latest release: ![GitHub latest release (latest by date)](https://img.shields.io/github/v/tag/reginaldford/sms)

 # How to Download and Run/Install a Release
 - At the [ Releases page ](https:#github.com/reginaldford/sms/releases)  , under 'Assets', you can find binary executable files for Linux, OpenBSD, and FreeBSD You may rename the file to 'sms' and copy to anywhere you need. On most Linux/Unix systems, copying to somewhere like /usr/local/bin directory is a fine way to install the program. The program is small and portable, so you can have copies where necessary.
