-# Contributing
-
-Contributions are accepted in any form (issues, documentation, feature requests, code, review, ...).
-
-All creatures welcome.
-
-If you have access, please contribute on the [CCCB Forgejo](https://git.berlin.ccc.de/servicepoint/servicepoint).
-Contributions on GitHub will be copied over and merged there.
-
-## Pull requests
-
-Feel free to create a PR, even if your change is not done yet.
-
-Mark your PR as a draft as long as you do not want it to be merged.
-
-The main branch is supposed to be a working version, including language bindings,
-which means sometimes your PR may be merged into a temporary development branch.
-
-Unit tests and documentation are required for the core library.
-
-## Language bindings
-
-Pull requests for your preferred language will be accepted.
-If there is no code generator, it should call the C ABI methods provided by `servicepoint_binding_c`.
-It should be able to send most of the basic commands in a way the simulator accepts, receiving is
-not required for the merge.
-
-It is okay for the feature set of a language binding to lag behind the one of the rust crate.
-This also means you do not have to expose a feature to all the language bindings when adding something to the core.
-
-If your change may break other language bindings, please note that in your PR description so someone can check them.

 In [CCCB](https://berlin.ccc.de/), there is a big pixel matrix hanging on the wall.
 It is called  "Service Point Display" or "Airport Display".
 
-This crate contains C bindings for the `servicepoint` library, enabling users to parse, encode and send packets to this display via UDP.

-# About the display
-
-- Resolution: 352x160=56,320 pixels
-- Pixels are grouped into 44x20=880 tiles (8x8=64 pixels each)
-- Smallest addressable unit: row of pixels inside of a tile (8 pixels = 1 byte)
-- The brightness can only be set per tile
-- Screen content can be changed using a simple UDP protocol
-- Between each row of tiles, there is a gap of around 4 pixels size. This gap changes the aspect ratio of the display.
-
-### Binary format
-
-A UDP package sent to the display has a header size of 10 bytes.
-Each header value has a size of two bytes (unsigned 16 bit integer).
-Depending on the command, there can be a payload following the header.
-
-To change screen contents, these commands are the most relevant:
-
-1. Clear screen
-    - command: `0x0002`
-    - (rest does not matter)
-2. Send CP437 data: render specified text into rectangular region
-    - command: `0x0003`
-    - top left tile x
-    - top left tile y
-    - width in tiles
-    - height in tiles
-    - payload: (width in tiles * height in tiles) bytes
-        - 1 byte = 1 character
-        - each character is rendered into one tile (mono-spaced)
-        - characters are encoded using code page 437
-3. Send bitmap window: set pixel states for a rectangular region
-    - command: `0x0013`
-    - top left tile x
-    - top left _pixel_ y
-    - width in tiles
-    - height in _pixels_
-    - payload: (width in tiles * height in pixels) bytes
-        - network byte order
-        - 1 bit = 1 pixel
-
-There are other commands implemented as well, e.g. for changing the brightness.
