+# Pannellum
+
+## About
+
+Pannellum is a lightweight, free, and open source panorama viewer for the web. Built using HTML5, CSS3, JavaScript, and WebGL, it is plug-in free. It can be deployed easily as a single file, just 18kB gzipped, and then embedded into pages as an `<iframe>`. A configuration utility is included to generate the required code for embedding.
+
+## How to use
+1. Upload `build/pannellum.htm` and a full equirectangular panorama to a web server.
+2. Use the included configuration tool (`configuration.htm`).
+    * `Pannellum Location` is the address of `pannellum.htm` and can be either a full or relative path (relative to the page containing the `<iframe>`).
+    * `Panorama URL` is the address of the panorama image file and can be either a full or relative path (relative to `pannellum.htm`).
+    * `Basic Information` is optional. If provided, it is displayed in the bottom left corner.
+    * `Embed Size` is the dimensions of the `<iframe>`.
+    * `Include Pannellum Logo` includes the Pannellum logo in the upper right corner with a link to the project's website.
+    * `Auto Load` loads the panorama when the page is loaded. If left unchecked, the user must click to load the panorama.
+    * Selecting a `Creative Commons License` inserts a banner for the appropriate license next to the author's name.
+    * `Generate` creates the embed code that can then be copied wherever desired.
+3. Insert the generated `<iframe>` code into a page.
+
+## Examples
+
+Examples using both the minified version and the version in the `src` directory are included in the `examples` directory.
+
+## Browser Compatibility
