+# `protobuf-c` Runtime
+
+This is the [protobuf-c runtime](https://github.com/protobuf-c/protobuf-c/tree/master/protobuf-c), packaged for [Zig](https://ziglang.org/).
+
+## Status
+
+This project only builds the `protobuf-c` runtime library. It does not build `protoc-c`, the corresponding protocol buffers C language code generator.
+
+The runtime library depends only on a small amount of functionality from libc, so it should compile for most targets. Linux, macOS and Windows are tested by CI.
+
+## Usage
+
+First, update your `build.zig.zon`:
+
+```sh
+# Initialize a `zig build` project if you haven't already
+zig init
+# replace <refname> with the version you want to use, e.g. 1.5.0
+zig fetch --save git+https://github.com/allyourcodebase/protobuf-c#<refname>
+```
+
+You can then use `protobuf_c` in your `build.zig` with:
+
+```zig
+const protobuf_c_dep = b.dependency("protobuf_c", .{
+    .target = target,
+    .optimize = optimize,
+});
+your_exe.linkLibrary(protobuf_c_dep.artifact("protobuf_c"));
+```
