+# qbolt
+
+A graphical database manager for BoltDB.
+
+QBolt allows you to graphically view and edit the content of Bolt databases.
+
+Written in Golang (Qt)
+
+## Features
+
+- Open existing database or create new database
+- Option to open database as readonly for concurrent use
+- Create, list, edit and delete keys and buckets (including nested buckets)
+- Safe for use with arbitrary binary key/bucket names (new ones created in UTF-8)
+- View database and bucket statistics
+- 100% Bolt compatibility via the real codebase
+- Tested working on both Windows and Linux
+
+## License
+
+Source code content of `qbolt-x.x.x-src.tar.gz` is released under the ISC license.
+BoltDB is released under the MIT license.
+The Windows binary is released under LGPL-3+ owing to the static copy of Qt.
