+# uuid-v7
+
+[![JSR](https://jsr.io/badges/@babia/uuid-v7)][jsr]
+[![JSR Score](https://jsr.io/badges/@babia/uuid-v7/score)][jsr]
+[![CI](https://github.com/babiabeo/uuid-v7/actions/workflows/ci.yml/badge.svg)](https://github.com/babiabeo/uuid-v7/actions/workflows/ci.yml)
+
+The `uuid-v7` package provides UUIDv7 generator and validator based on [RFC 9562][rfc].
+
+UUIDv7 features a time-ordered value field derived from the widely implemented
+and well-known Unix Epoch timestamp source, the number of milliseconds since
+midnight 1 Jan 1970 UTC, leap seconds excluded.
+
+## Quick start
+
+#### Install
+
+This package is available on [jsr.io][jsr].
+
+```sh
+# Deno
+deno add @babia/uuid-v7
+
+# npm
+npx jsr add @babia/uuid-v7
+
+# yarn
+yarn dlx jsr add @babia/uuid-v7
+
+# pnpm
+pnpm dlx jsr add @babia/uuid-v7
+
+# Bun
+bunx jsr add @babia/uuid-v7
+```
+
+#### Example: Generate a new uuid
+
+```ts
+import { generate } from "@babia/uuid-v7";
+
+generate() // => 01912d68-783e-7a03-8467-5661c1243ad4
+```
+
+## Documentation
