-# ServicePoint
-
-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.
-
-## Examples
-
-```csharp
-using ServicePoint;
-
-// using statement calls Dispose() on scope exit, which frees unmanaged instances
-using var connection = Connection.Open("127.0.0.1:2342");
-using var pixels = Bitmap.New(Constants.PixelWidth, Constants.PixelHeight);
-
-while (true)
-{
-    pixels.Fill(true);
-    connection.Send(Command.BitmapLinearWin(0, 0, pixels.Clone()));
-    Thread.Sleep(5000);
-
-    pixels.Fill(false);
-    connection.Send(Command.BitmapLinearWin(0, 0, pixels.Clone()));
-    Thread.Sleep(5000);
-}
-```
-
-A full example including project files is available as part of this crate.
-
-## Note on stability
-
-This library is still in early development.
-You can absolutely use it, and it works, but expect minor breaking changes with every version bump.
-
-## Installation
-
-NuGet packages are not a good way to distribute native projects ([relevant issue](https://github.com/dotnet/sdk/issues/33845)).
-Because of that, there is no NuGet package you can use directly.
-Including this repository as a submodule and building from source is the recommended way of using the library.
-
-```bash
-git submodule add https://github.com/cccb/servicepoint.git
-git commit -m "add servicepoint submodule"
-```
-
-You can now reference `servicepoint-bindings-cs/src/ServicePoint.csproj` in your project.
-The rust library will automatically be built.
-
-Please provide more information in the form of an issue if you need the build to copy a different library file for your platform.
-
-## Notes on differences to rust library
-
-Uses C bindings internally to provide a similar API to rust. Things to keep in mind:
-
-- You will get a `NullPointerException` when trying to call a method where the native instance has been consumed already (e.g. when `Send`ing a command instance twice). Send a clone instead of the original if you want to keep using it.
-- Some lower-level APIs _will_ panic in native code when used improperly.
-  Example: manipulating the `Span<byte>` of an object after freeing the instance.
-- C# specifics are documented in the library. Use the rust documentation for everything else. Naming and semantics are the same apart from CamelCase instead of kebab_case.
-- You will only get rust backtraces in debug builds of the native code.
-- F# is not explicitly tested. If there are usability or functionality problems, please open an issue.
-- Reading and writing to instances concurrently is not safe. Only reading concurrently is safe.
-
-## Everything else
-
-Look at the main project [README](https://github.com/cccb/servicepoint/blob/main/README.md) for further information.
