 ## Running
 
-The application can be easily deployed to and run from a web server.
-Simply clone the repository to a web server and serve the directory.
+The application requires Yarn to build. Once it is installed, run
+`yarn build` to build the bundle. Upload everything in the `dist/`
+directory to a webserver and serve the directory as static files.

+## Technologies
+
+This small project is partly a playground for over-engineering. The
+technologies used are:
+
+ - **XSLT and XML:** Ancient, but still working in all browsers.
+   Easiest way to parse and view the backup files.
+ - **Typescript:** It's JavaScript, but better.
+ - **SASS**: It's CSS, but better.
+ - **Parcel:** Bundling tool with minimal configuration required to
+   build the web application.
+ - **Dexie (IndexedDB):** For saving previously-viewed backup files.
+ - **Bootstrap:** I am not good at making beautiful websites.
+   Bootstrap almost makes it look like I know what I'm doing.
