 Easy to use, hand-crafted API with default arguments, named parameters and Zig style text formatting. [Here](https://github.com/michal-z/zig-gamedev/tree/main/samples/minimal_zgpu_zgui) is a simple sample application, and [here](https://github.com/michal-z/zig-gamedev/tree/main/samples/gui_test_wgpu) is a full one.

 ## Getting started
 
-Copy `zgui` folder to a `libs` subdirectory of the root of your project and add the following to your `build.zig.zon` .dependencies:
+Copy `zgui` to a subdirectory in your project and add the following to your `build.zig.zon` .dependencies:
 ```zig
     .zgui = .{ .path = "libs/zgui" },
 ```
 
-To get glfw/wgpu rendering backend working also copy `zgpu`, `zglfw`, `zpool` and `system-sdk` folders and add the depenency paths (see [zgpu](https://github.com/zig-gamedev/zig-gamedev/tree/main/libs/zgpu) for the details). Alternatively, you can provide your own rendering backend by specifying `.no_backend` in the package options.

 Then in your `build.zig` add:

-const zglfw = @import("zglfw");
-const zgpu = @import("zgpu");

-You may also include zgui without bundled imgui or implot:
-
-```zig
-// In build.zig
-
-    const pkg = zgui.package(b, exe.target, .ReleaseSafe, .{
-        .options = .{
-            .backend = .no_backend,
-            .with_imgui = false,

-    const lib = pkg.zgui_c_cpp;
-    lib.defineCMacro("IMGUI_USER_CONFIG",
-        \\"../imconfig_custom.h"
-    );
-    lib.addIncludePath("lib/imgui");
-```
