+[Zig Object Notation (ZON)](https://ziglang.org/documentation/master/#ZON)
+text into objects, arrays, and scalar values. Available for
+TypeScript and Go.
+
+ZON is the data format used for Zig `build.zig.zon` manifests and
+similar configuration files. It is based on Zig anonymous struct
+literals, and looks like this:
+
+```zon
+.{
+    .name = "example",
+    .version = "0.0.1",
+    .dependencies = .{
+        .foo = .{
+            .url = "https://example.com/foo.tar.gz",
+            .hash = "1220deadbeef",
+        },
+    },
+    .paths = .{
+        "build.zig",
+        "src",
+    },
+}
+```
 
 ## Quick example
 
 **TypeScript**
 
 ```typescript
 import { Jsonic } from 'jsonic'
-import { Csv } from '@jsonic/csv'
+import { Zon } from '@jsonic/zon'
 
-const parse = Jsonic.make().use(Csv)
+const parse = Jsonic.make().use(Zon)
 
-parse("name,age\nAlice,30\nBob,25")
-// [{ name: 'Alice', age: '30' }, { name: 'Bob', age: '25' }]
+parse('.{ .name = "Alice", .age = 30 }')
+// { name: 'Alice', age: 30 }
 
-parse('a,b\n1,"hello, world"')
-// [{ a: '1', b: 'hello, world' }]
+parse('.{ 1, 2, 3 }')
+// [1, 2, 3]
 ```
 
 **Go**
 
 ```go
-import csv "github.com/jsonicjs/csv/go"
+import zon "github.com/jsonicjs/zon/go"
+import jsonic "github.com/jsonicjs/jsonic/go"
 
-result, _ := csv.Parse("name,age\nAlice,30\nBob,25")
-// [{name:Alice age:30} {name:Bob age:25}]
-```
+j := jsonic.Make()
+j.UseDefaults(zon.Zon, zon.Defaults)
 
+result, _ := j.Parse(`.{ .name = "Alice", .age = 30 }`)
+// map[string]any{"name": "Alice", "age": 30}
+```
 
-## Documentation
+## Supported syntax
 
-Full documentation following the [Diataxis](https://diataxis.fr)
-framework (tutorials, how-to guides, explanation, reference):
+- Anonymous struct literals: `.{ .field = value, ... }`
+- Tuple / array literals: `.{ value, value, ... }`
+- Field names: `.identifier`
+- Enum literals (used as values): `.identifier` (parsed as bare strings)
+- Strings: `"..."` with Zig escape sequences (`\n`, `\r`, `\t`, `\\`, `\"`, `\'`)
+- Multi-line strings: consecutive lines starting with `\\`
+- Numbers: decimal, `0x` hex, `0o` octal, `0b` binary, with `_` separators
+- Character literals: `'x'`, `'\n'`, `'\x41'`, `'\u{1F600}'`
+- Keywords: `true`, `false`, `null`
+- Line comments: `// ...`
+- Trailing commas allowed
