+# CLMDB
+
+CLMDB is a SwiftPM package wrapper for [LMDB](http://www.lmdb.tech/doc/), a key-value database storage solution created for fast read and write processes. You can read more about this project at: <http://www.lmdb.tech/doc>.
+
+This wrapper provides exposure of the library's C interfaces to Swift, allowing a Swift application or service to easily create, read, and manage database instances of LMDB.
+
+Changes in LMDB will be pulled into this repository as the upstream project evolves. The LMDB repository is mirrored here: <https://github.com/LMDB/lmdb>.
+
+## License
+
+The included LMDB database project is released under [The OpenLDAP Public License](https://git.openldap.org/openldap/openldap/-/blob/mdb.master/libraries/liblmdb/LICENSE). This same license applies to the Swift code included in this repository.
