+JFileServer H2 Database Filesystem
+==================================
+
+Introduction
+------------
+JFileServer is a Java based file server that currently supports the SMB/CIFS, FTP/FTPS
+and NFS protocols. A virtual filesystem interface allows custom filesystems to be implemented,
+with a database filesystem framework that makes it easy to use a database to store the filesystem
+metadata, and optionally the file data.
+
+The file server is highly scalable using asynchronous I/O, thread pools and memory pools
+to optimise the throughput. The server may be clustered for additional scaleability based
+on the Hazelcast cluster technology.
+
+An Enterprise add-on module adds support for SMBv2 (higher performance) and SMBv3 (full encryption).
+
+The H2 database filesystem driver stores the filesystem metadata in an H2 database. The
+file data may also be stored in the database, or it can be stored on the local filesystem, depending on
+the configuration. Storing the file data in the database also has options for packing multiple files
+into jar files which are then stored within the database, with an option to compress the data.
+
+History
+-------
+The JFileServer code originally started out as the JLAN Server, the first version being
+released by Starlasoft back in the late 1990's with basic SMB1 support. As development of
+the JLAN Server continued, SMB1 support was enhanced, and FTP and NFS support were added,
+along with the database filesystem framework and smart caching.
+
+In 2007 Alfresco Software bought the rights to the JLAN Server code rebranding it as Alfresco-JLAN,
+and releasing the code as open source. Development continued with the addition of support for 
+NTLMv2 and Kerberos enterprise authentication, scalability enhancements using NIO, thread
+pools and memory pools, plus cluster support using Hazelcast, and FTPS support.
+
+In recent years no new development has been done on the Alfresco-JLAN code.
+
+At the beginning of 2018 we forked the Alfresco-JLAN code to create the JFileServer project
+to bring the source code up to date, and continue development of the file server.
+
+License
+-------
+The core JFileServer library and components such as the database filesystem implementations
+are licensed under the same GNU LGPL v3.0 license as the original Alfresco-JLAN code.
+
+JDK Version
+-----------
+The JFileServer code uses features of JDK version 8 onwards.
+
+Docker
+------
+Pre-configured setups of the core JFileServer and various database fileserver implementations
+are available as Docker images which can either be used as they are or used as the starting
+point for your own configurations.
+
+For a list of the available Docker images see <https://hub.docker.com/r/filesysorg/>.
