+# Image Buffer -> Base64
+
+This program returns a Base64 encoding of an image buffer (from either the web or local file) as STDOUT (a standard output), meaning that you can run the file and use whatever it logs/outputs.
+
+## Help Menu
+- `-h <url>`                    sends a http get request to the url and returns Base64 encoding of the image
+- `--http <url>`                same as above
+- `-r <path/to/file>`           fs module reads file and returns Base64 encoding of the image
+- `--readFile <path/to/file>`   same as above
+
+## How To Build
+
+Install all of the modules...
+```sh
+$ npm install
+```
+  
+Compile the TypeScript source code into Commonjs, create executables and store them locally...
+```sh
+$ npm run build
+```
+
+## Why not use the Base64 Linux command?
+Because... why not? 😈
+
+(Pull Requests are also accepted | also needing help on how to add commands in NT & OSX)
