+# Lightweight Image Viewer
+A lightweight, browser-based image viewer originally made to view enormous amounts of images on headless servers.  
+
+I suggest not running this on any port that is open to the internet.
+
+## How to run it
+
+```go run main.go```  
+
+The program is now listening on port `8080`
+
+## How to use it
+
+Everything after the port in the URL is considered a path to a directory.  
+To view the example images you have to visit this URL in your browser:
+```http://localhost:8080/tmp/ImageLight/examples```
