-# huepaper - a colorful wallpaper generator
-
-![Logo](images/logo.png)
-
-**huepaper** creates wallpapers based on color hues. Bring a little
-color in your life by randomness, because every huepaper is truly
-unique.
-
-You can find [examples](#examples) below. For more examples visit the
-Mastodon [huebot](https://botsin.space/@huebot).
-
-## Installation
-
-```shell
-pip install --index-url https://git.end-play.xyz/api/packages/profitroll/pypi/simple/ huepaper
-```
-
-## Usage
-
-```example
-usage: huepaper [-h] [--width WIDTH] [--height HEIGHT] [-c COLOR] [-np] [-o OUTPUT] [-l [LINES]] [-lb [LINES_BRIGHT]] [-ld [LINES_DARK]] [-p [PIXELATE]] [-e EMBLEM] [-hue HUE] [-smin SMIN] [-smax SMAX] [-lmin LMIN] [-lmax LMAX]
-
-Create wallpapers based on color hues.
-
-optional arguments:
-  -h, --help            show this help message and exit
-  --width WIDTH         width of the image (default: 1920)
-  --height HEIGHT       height of the image (default: 1080)
-  -c COLOR, --color COLOR
-                        base color from which the huepaper is generated (default: random color)
-  -o OUTPUT, --output OUTPUT
-                        filepath where the huepaper will be saved
-  -l [LINES], --lines [LINES]
-                        include one to three random lines in base color with given opacity in range [0, 1] (default: 0.3)
-  -lb [LINES_BRIGHT], --lines_bright [LINES_BRIGHT]
-                        include one to three bright random lines with given opacity in range [0, 1] (default: 0.1)
-  -ld [LINES_DARK], --lines_dark [LINES_DARK]
-                        include one to three dark random lines with given opacity in range [0, 1] (default: 0.1)
-  -p [PIXELATE], --pixelate [PIXELATE]
-                        pixelate image with WIDTHxHEIGHT (default: 16x9)
-  -e EMBLEM, --emblem EMBLEM
-                        emblem to add in the center of the huepaper
-  -hue HUE              maximum hue to differ from given color in range [0, 1] (default: 0.1)
-  -smin SMIN            minimum saturation for colors in range [0, 1] (default: 0.2)
-  -smax SMAX            maximum saturation for colors in range [0, 1] (default: 1.0)
-  -lmin LMIN            minimum luminance for colors in range [0, 1] (default: 0.2)
-  -lmax LMAX            maximum luminance for colors in range [0, 1] (default: 0.9)
-```
-
-...or as a Python module
-
-```python
-from huepaper import generate
-
-image = generate(width=500, height=500, hue_max=1.0, lum_min=0.3, lum_max=0.6, sat_min=0.8, sat_max=1.0)
-```
-
-All image operations are called in order of the help file. E.g. pixelate
-(`-p`) is called after adding lines (`-l`).
-
-If you set the color via `-c` it is not guaranteed, that it
-is included in the huepaper. Colors, similar to the given one are
-chosen. You can specify how far the colors differ in the hue range with
-the `-hue` parameter. Valid color expressions are e.g.
-`#F5F5DC`, `#0f0`, `ffff80` and
-`red`. Make sure, that colors beginning with a `#`
-are encapsulated in quotes. All supported color names can be seen
-[here](https://www.w3schools.com/colors/colors_names.asp).
-
-If you use the `-e` argument to specify an emblem, make sure
-it has the correct size. It is not scaled or stretched, just placed in
-the center of the image. If you want an offset, e.g. put it in the left
-bottom corner, provide an emblem file with the size of the huepaper,
-transparent background and your emblem in the bottom left corner.
-
-## Examples
-
-Please note, that every huepaper call generates a new random image. You
-will never get the same huepaper twice. You may like some and dislike
-others. Fiddle around with the options to find a result, you are happy
-with.

+* huepaper - a colorful wallpaper generator
+
+  #+caption: Logo
+  [[./images/logo.png]]
+
+ *huepaper* creates wallpapers based on color hues. Bring a little color in your life by randomness, because every huepaper is truly unique.
+
+  You can find [[#examples][examples]] below.
+  For more examples visit the Mastodon [[https://botsin.space/@huebot][huebot]].
+
+** Installation
+
+*** Nix
+
+    This project is a [[https://nixos.wiki/wiki/Flakes][Nix Flake]].
+    If you have a recent version of the [[https://nixos.org/][Nix package manager]] installed and Flakes are enabled, run huepaper like this:
+
+    : $ nix run github:Deleh/huepaper
+
+    Parameters can be passed by appending a double-dash:
+
+    : $ nix run github:Deleh/huepaper -- -hue 0.5 --color lightblue
+
+    Global installation can be done by including this flake in your flaked NixOS configuration as always :)
+
+*** Legacy
+
+    Execute the following steps to run huepaper:
+
+    : $ pip install -r requirements.txt
+    : $ ./huepaper.py
+    #+end_example
+
+    To install it in your Python environment run:
+
+    : $ python setup.py install
+
+** Usage
+
+   #+begin_example
+     usage: huepaper [-h] [-s SIZE] [-c COLOR] [-np] [-o OUTPUT] [-l [LINES]] [-lb [LINES_BRIGHT]] [-ld [LINES_DARK]] [-P [PIXELATE]] [-e EMBLEM] [-hue HUE] [-smin SMIN] [-smax SMAX] [-lmin LMIN] [-lmax LMAX]
+
+     Create wallpapers based on color hues.

+       -p [PIXELATE], --pixelate [PIXELATE]
+                             pixelate image with WIDTHxHEIGHT (default: 16x9)

+                             emblem to add in the center of the huepaper

+       -lmax LMAX            maximum luminance for colors in range [0, 1] (default: 0.9)
+   #+end_example
+
+   All image operations are called in order of the help file. E.g. pixelate (=-p=) is called after adding lines (=-l=).
+
+   If you set the color via =-c= it is not guaranteed, that it is included in the huepaper.
+   Colors, similar to the given one are chosen.
+   You can specify how far the colors differ in the hue range with the =-hue= parameter.
+   Valid color expressions are e.g. =#F5F5DC=, =#0f0=, =ffff80= and =red=.
+   Make sure, that colors beginning with a =#= are encapsulated in quotes.
