 Since there's no package manager for Zig yet, the recommended way is to use a git submodule:
 
 ```bash
-$ git submodule add https://github.com/vrischmann/zig-sqlite.git src/sqlite
+$ git submodule add https://github.com/vrischmann/zig-sqlite.git third_party/zig-sqlite

+If you want to use the system sqlite library, add the following to your `build.zig` target(s):
 
 ```zig

 exe.linkSystemLibrary("sqlite3");

+If you want to use the bundled sqlite source code file, first you need to add it as a static library in your `build.zig` file:
 
 ```zig
-const sqlite = @import("sqlite");
+const sqlite = b.addStaticLibrary("sqlite", null);
+sqlite.addCSourceFile("third_party/zig-sqlite/sqlite3.c", &[_][]const u8{"-std=c99"});

+Now it's just a matter of linking your `build.zig` target(s) to this library instead of the system one:
+
+```zig
+exe.linkLibC();
+exe.linkLibrary(sqlite);
+exe.addPackage(.{ .name = "sqlite", .path = "third_party/zig-sqlite/sqlite.zig" });
 ```
 
 # Usage
 
+Import `zig-sqlite` like this:
+
+```zig
+const sqlite = @import("sqlite");
+```

 ## Initialization
 
 You must create and initialize an instance of `sqlite.Db`:
