Subject: [PATCH] Compile and installation method updates

created setup, build and install scripts to make it easier and
convenient to compile and install the application from source. no plans
distribute pre-compiled binaries because it's just so much easier to
guarantee the application will actually work in the target machine when
compiled by the target machine.

-### Build Setup ###
+### Setup/Build/Install ###
 
 This application is currently only compatible with a Linux based operating
 systems that are capable of building and installing the opencv API from source.
 
-[opencv](https://docs.opencv.org/4.x/df/d65/tutorial_table_of_content_introduction.html).
+The following 3 scripts make this convenient by downloading, compiling and then
+installing the opencv API for you directly from opencv's git repository. This
+also makes sure FFMPEG and all of it's dependencies are installed because this
+application needs it to work properly.
+
+note 1: be sure to run setup.sh and install.sh as root (or use sudo).
+note 2: if building from scratch the following scripts will need to
+        be run in this order - setup.sh -> build.sh -> install.sh.
+
 ```
-cd /path/to/Motion/Watch/source
-mkdir ./build
-cd ./build
-cmake ..
-make
-sudo cp ./mow /usr/bin/mow
+sh ./setup.sh <--- only need to run this once if compiling for the first
+sh ./build.sh      time or if upgrading from the ground up.
+sh ./install.sh
 ```
