+# zig-wayland
+
+Zig bindings and protocol scanner for libwayland.
+
+## Usage
+
+A `ScanProtocolsStep` is provided which you may intergrate with your
+`build.zig`:
+
+```zig
+const std = @import("std");
+const Builder = std.build.Builder;
+
+const ScanProtocolsStep = @import("zig-wayland/build.zig").ScanProtocolsStep;
+
+pub fn build(b: *Builder) void {
+    const target = b.standardTargetOptions(.{});
+    const mode = b.standardReleaseOptions();
+
+    var scanner = ScanProtocolsStep.create(b, "zig-wayland/", .client);
+    scanner.addSystemProtocol("stable/xdg-shell/xdg-shell.xml");
+    scanner.addProtocolPath("protocol/foobar.xml");
+
+    const exe = b.addExecutable("foo", "foo.zig");
+    exe.setTarget(target);
+    exe.setBuildMode(mode);
+
+    exe.step.dependOn(&scanner.step);
+    exe.addPackage(scanner.getPkg());
+    scanner.link(exe);
+
+    exe.install();
+}
+
+```
+
+Then, you may import the provided package in your project:
+
+```zig
+const wayland = @import("wayland");
+const wl = wayland.client.wl;
+```
+
+There is an example project using zig-wayland here:
+[hello-zig-wayland](https://github.com/ifreund/hello-zig-wayland).
