# libchdr
4+
5+
This is [libchdr](ttps://github.com/rtissera/libchdr), packaged for [Zig](https://ziglang.org/).
6+
7+
## Installation
8+
9+
First, update your `build.zig.zon`:
10+
11+
```
12+
# Initialize a `zig build` project if you haven't already
13+
zig init
14+
zig fetch --save git+https://github.com/allyourcodebase/libchdr.git
15+
```
16+
17+
You can then import `libchdr` in your `build.zig` with:
18+
19+
```zig
20+
const bzip_dependency = b.dependency("libchdr", .{
21+
.target = target,
22+
.optimize = optimize,
23+
});
24+
your_exe.linkLibrary(bzip_dependency.artifact("chdr"));
25+
```
26+
