 # Notes for Development
-All changes to the client side files can be made in the `examples/gui/data` directory. Using the file uploader then can be used for development. After this you have to compress them and then you can gzip them. I wrote a little useful jsfiddle for this, [CHECK IT OUT](https://jsfiddle.net/s00500/yvLbhuuv/)... or there is the `prepare_static_ui_sources.py` script in the `tools` directory, if you have a python3 environment available (you also need the modules jsmin, htmlmin and csscompressor).
+If you want to work on the HTML/CSS/JS files, do make changes in the `examples/gui/data` directory. When you need to transfer that code to the ESP, run `tools/prepare_static_ui_sources.py -a` (this script needs python3 with the modules htmlmin, jsmin and csscompressor).
+This will generate a) minified files next to the original files to be uploaded with the ESP32 sketch data uploader mentioned above and b) the C header files in `src` that contain the minified and gzipped HTML/CSS/JS data (which are used by the **prepareFileSystem** example sketch or when they are served from PROGMEM; see above in the section "Getting started").
+Alternatively, you can duplicate the `examples/gui` directory and work on the copy. Then specify the `--source` and `--target` arguments to the `prepare_static_ui_sources.py` script (run the script without arguments for help).
+
+If you don't have a python environment, you need to minify and gzip the HTML/CSS/JS files manually. I wrote a little useful jsfiddle for this, [see here](https://jsfiddle.net/s00500/yvLbhuuv/).
+
+If you change something in HTML/CSS/JS and want to create a pull request, please do include the minified versions and corresponding C header files in your commits.
