-## Getting started (Filesystem upload)
+## Getting started
 
-ESPUI **NEEDS** its files burnt on the SPIFFS filesystem on the ESP. **Without this ESPUI will NOT work at all**
-There are now two ways to do this: you can either use the upload tool or you use the library function `ESPUI.prepareFileSystem()`
+ESPUI serves several files to the browser to build up its webinterface. This can be achieved in 2 ways: 
+*PROGMEM* or *SPIFFS*
 
-#### Simple filesystem preparation (recomended)
+*When `ESPUI.begin()` is called the default is serving files from Memory and ESPUI should work out of the box!*
 
-Just open the example sketch **prepareFileSystem** and run it on the ESP, (give it 5 - 10 seconds),
+But if this causes your program to *use too much memory* you can burn the files into the SPIFFS filesystem on the ESP.

 The library will create all needed files.
 Congratulations, you are done, from now on you just need to to this again when there is a library update, or when you want to use another chip :-)
 Now you can upload your normal sketch, when you do not call the `ESPUI.prepareFileSystem()` function the compiler will strip out all the unnecessary that is already saved in the chip's filesystem and you have more programm memory to work with.

 This section will explain in detail how the Library is to be used from the Arduino code side. As of now the Facilino blocks are not implemented.
-In the arduino setup() routine the interface can be customised by adding UI Elements. This is done by calling the corresponding library methods on the Library object ESPUI. Eg: ESPUI.button(“button”, &myCallback); creates a button in the interface that calls the “myCallback” function when changed. All buttons and items call their callback whenever there is a state change from them. This means the button will call the callback when it is pressed and also again when it is released. To separate different events an integer number with the event name is passed to the callback function that can be handled in a switch(){}case{} statement. Here is an overview of the currently implemented different elements of the UI library:

-Labels are a nice tool to get information from the robot to the user interface. This can be done to show states, values of sensors and configuration parameters.

+Labels automatically wrap your text. If you want them to have multiple lines use the normal `<br>` tag in the string you print to the label
 
 #### Slider
 
-There is also an slider component now, needs to be documented though
+![labels](https://github.com/s00500/ESPUI/blob/master/docs/ui_slider.png)
+
+The Slider can be used to slide through a value from 1 to 100. Slides provide realtime data, are touch compatible and can be used to for example control a Servo. The current value is shown while the slider is dragged in a little bubble over the handle.
 
 #### Initialisation of the UI
 
-After all the elements are configured you can use ESPUI.begin(“Some Title”); to start the UI interface. Make sure you setup a working network connection or AccesPoint **before** (See example). The web interface can then be used from multiple devices at once and also shows an connection status in the top bar.
+After all the elements are configured you can use `ESPUI.begin(“Some Title”);` to start the UI interface. (Or `ESPUI.beginSPIFFS(“Some Title”);` respectively) Make sure you setup a working network connection or AccesPoint **before** (See example). The web interface can then be used from multiple devices at once and also shows an connection status in the top bar.
 The library is designed to be easy to use and can still be extended with a lot of more functionality.
 
 
+# Notes for Development
+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.
