+# YDotNet
+
+YDotNet is a .NET binding for [`y-crdt`](https://github.com/y-crdt/ypy). It provides distributed data types that enable
+real-time collaboration between devices. The library is a thin wrapper around Yrs, taking advantage of the safety and performance of Rust.
+
+> 💡 Disclaimer: this project is still early, so it may contain bugs and the API is subject to change. Feel free to
+> [open an issue](https://github.com/LSViana/ydotnet/issues/new) if you'd like to report problems or suggest new features.
+
+# Installation
+
+> This section is a WIP, the project has not yet been published to [NuGet](https://www.nuget.org/).
+
+# Getting Started
+
+YDotNet provides the same shared data types as [Yjs](https://docs.yjs.dev/). All objects are shared within a
+[`Doc`](https://github.com/LSViana/ydotnet/blob/5c51f761f608d03fc88edaaf31aee4608afe0d3e/YDotNet/Document/Doc.cs) and always get modified within
+the scope of a [`Transaction`](https://github.com/LSViana/ydotnet/blob/5c51f761f608d03fc88edaaf31aee4608afe0d3e/YDotNet/Document/Transactions/Transaction.cs).
+
+```csharp
+// Set up the local document with some sample data.
+var localDoc = new Doc();
+var localText = localDoc.Text("name");
+
+var localTransaction = localDoc.WriteTransaction();
+localText.Insert(localTransaction, 0, "Y-CRDT");
+localTransaction.Commit();
+
+// Set up the remote document.
+var remoteDoc = new Doc();
+var remoteText = remoteDoc.Text("name");
+
+// Get the remote document state vector.
+var remoteTransaction = remoteDoc.WriteTransaction();
+var remoteState = remoteTransaction.StateVectorV1();
+
+// Calculate the state diff between the local and the remote document.
+localTransaction = localDoc.ReadTransaction();
+var stateDiff = localTransaction.StateDiffV1(remoteState);
+localTransaction.Commit();
+
+// Apply the state diff to synchronize the remote document with the local changes.
+var result = remoteTransaction.ApplyV1(stateDiff);
+
+// Read the text from the remote document.
+var text = remoteText.String(remoteTransaction);
+
+// At this point, the `text` variable is "Y-CRDT" and this demonstrates how the two
+// documents synchronized their state.
+//
+// This example does it locally but the same could be done over the Internet, for example.
+```
+
+# Development Setup
+
+> This section is a WIP, but you should be able to run the project through the unit tests after
+> building a dynamic library for your operating system by adding `cdylib` to the `crate-type` in
+> the [`Cargo.toml`](https://github.com/y-crdt/y-crdt/blob/main/yffi/Cargo.toml#L19) file of the
+> yffi` library.
+
+# Tests
+
+All tests are located in the [`YDotNet.Tests.Unit`](https://github.com/LSViana/ydotnet/tree/main/Tests/YDotNet.Tests.Unit)
+project and should be easily runnable using the command:
+
+```sh
+dotnet test
+```
