+
+## API
+
+Exports a single function which takes a single argument, an `abstract-leveldown` compatible storage back-end for [`levelup`](https://github.com/Level/levelup). The function returns a constructor function that will bundle `levelup` with the given `abstract-leveldown` replacement. The full API is supported, including optional functions, `destroy()`, and `repair()`. Encoding functionality is provided by [`encoding-down`](https://github.com/Level/encoding-down).
+
+The constructor function has a `.errors` property which provides access to the different error types from [`level-errors`](https://github.com/Level/errors#api).
+
+For example use-cases, see:
+
+- [`level`](https://github.com/Level/level)
+- [`level-mem`](https://github.com/Level/level-mem)
+- [`level-hyper`](https://github.com/Level/level-hyper)
+- [`level-lmdb`](https://github.com/Level/level-lmdb)
+
+Also available is a _test.js_ file that can be used to verify that the user-package works as expected.

+# Upgrade Guide
+
+This document describes breaking changes and how to upgrade. For a complete list of changes including minor and patch releases, please refer to the [changelog](CHANGELOG.md).
+
+## v5
+
+Upgraded to [`levelup@4`](https://github.com/Level/levelup/blob/v4.0.0/UPGRADING.md#v4) and [`encoding-down@6`](https://github.com/Level/encoding-down/blob/v6.0.0/UPGRADING.md#v6). We recommend to pair `level-packager@5` only with a store based on `abstract-leveldown` >= 6. Please follow the earlier links for more information.
+
+## v4
+
+The `test.js` file was rewritten to test the `level-packager` api and is no longer part of the api. Implementations based on `level-packager` should instead use the tests in the `abstract/` folder.
+
+## v3
+
+Dropped support for node 4. No other breaking changes.
