-# Convertron3000
-
-Convertron3000 is a graphics converter for Commodore 64 computers.
-It runs on 64 bit versions of Linux, MacOS and Windows.
-
-
-# Why Convertron3000?
-
-reason | description
----|---
-open source | easy to modify and to improve, any useful contribution is highly welcome
-portable | available on Linux, MacOS, Darwin and any other system supported by Python3
-instant preview | just fiddle around with the sliders and see the result before converting
-
-
-# Usage
-
-Using Convertron3000 is pretty straight-forward:
-
-* Open some image.
-* Adjust the sliders or apply an effect.
-* Convert to koala or hires format.
-* Save the resulting image.
-
-
-# Brightness palette
-
-Sometimes converted images look better when applying a palette based on brightness values.
-
-* Select "brightness palette" mode.
-* Choose one of the presets ("purple", "brown" etc.).
-
-You can also create your own palette like this:
-
-* Edit the .json file: In the .json file you specify the size of your palette and the C64-colors like in one of the examples provided.
-* Open your .json file. You find this option in the drop-down menu under "open custom gradient".
-* Choose "custom" as your brightness palette.
-
-
-
-
-# File Formats
-
-The multicolor bitmap is stored in the widely-spread KoalaPainter (.koa) format:
-
-* 2 bytes load address
-* 8000 bytes raw bitmap data
-* 1000 bytes raw "Video Matrix" (screen) data
-* 1000 bytes raw "Color RAM" data
-* 1 byte background data
-
-The hires bitmap is stored in the widely-spread Advanced Art Studio (.art) format:
-
-* 2 bytes load address
-* 8000 bytes raw bitmap data
-* 1000 bytes raw "Video Matrix" (screen) data

-# Getting Started
-
-Convertron3000 comes in two flavors:
-
-- standalone executable for 64-bit systems Linux, MacOS/Darwin and Windows
-- Python3 script
-
-## Run the standalone executable
-
-Just download your bundle and enjoy. Keep in mind that only 64bit systems are supported as I could not find a 32bit system to generate the bundle.
-
-### Note for Windows users
-
-If some antivirus scanner puts Convertron3000 into quarantine because it suspects a trojan or virus, simply put it out there again.
-It isn`t harmful, I used PyInstaller to bundle the standalone executable for you.
-Unfortunately, the PyInstaller bootloader triggers a false alarm on some systems.
-I even tried my best and re-compiled the PyInstaller bootloader so that this should not happen anymore. Keep your fingers crossed ;)
-
-### Note for MacOS users
-
-Your system might complain that the code is not signed by a certificated developer. Well, I am not, so I signed the program on my own. 
-```
-"Convertron3000" can`t be opened because it is from an unidentified developer.
-```
-You need to right-click or Control-click the app and select “Open”.
-
-
-
-## Run the Python3 script directly
-
-Download _convertron.py_ and the whole _resource_ - directory into the same folder on your computer.
-
-### Prerequisites
-
-At least this is needed to run the script directly:
-
-- python 3
-- python tkinter module
-- python "The Python Imaging Library" (PIL)
-
-On my Debian GNU/Linux machine I use apt-get to install everything needed:
-```
-apt-get update
-apt-get install python3 python3-tk python3-pil
-```
