 With an existing zig project, adding zap to it is easy:
 
-1. Add zap as a git submodule 
+1. Add zap to your `build.zig.zon` 
 2. Add zap to your `build.zig` 
 
-To add zap as a git submodule:
-
-```shell 
-$ mkdir libs
-$ git submodule add https://github.com/renerocksai/zap.git libs/zap
-```
-
-Then, add the following at the top of your `build.zig`:
-
-```zig
-const zap_builder = @import("./libs/zap/build.zig");
-
-const zap = std.build.Pkg{
-    .name = "zap",
-    .source = std.build.FileSource{ .path = "./libs/zap/src/zap.zig" },

 From then on, you can use the zap package in your project. Check out the
