 - Register AFM fonts provided by pdfkit
 - Shows how to load and register files lazily
 
-### Remarks
+### Technical details
 
-Refer to webpack.config.js to details about configuration
+[`webpack.config.js`](webpack.config.js)
+
+- add alias to map `fs` calls to pdfkit virtual file system [implementation](../../lib/virtual-fs.js)
+- ignore iconv-lite and crypto packages to save bundle file size
+- add aliases to native node packages (buffer, stream, zlib, util, assert)
+- configure `*.afm` files to be imported as text
+- configure all files in `src/static-assets` folder to be imported encoded as base64
+- configure all files in `src/lazy-assets` folder to be imported as URLs
+- convert binary files used by linebreak and fontkit to base64
+
+### Caveats
+
+The strategy to register binary files and AFM fonts inlines them in source code, increasing the bundle size significantly
