+# sqlite-uuidv7
+
+An SQLite extension for generating
+[UUIDv7s](https://datatracker.ietf.org/doc/html/draft-peabody-dispatch-new-uuid-format).
+It wraps https://github.com/gofrs/uuid.
+
+## Usage
+
+You will need a version of SQLite that allows loading of extensions. If you are
+on a Mac, you can `brew install sqlite`.
+
+```text
+$ make 
+$ sqlite3
+> .load uuidv7.so
+> select uuid_generate_v7();
+018898f3-3067-703b-8292-e2def527c6b4
+> sqlite> select quote(uuid_generate_v7_bytes());
+X'018898F33745703BA7618E0C33AECF3E'
+> .quit
+```
+
+## Tests
+
+Yes, I should add tests.
