+YBDB relies heavily on accurate time calculations. 
+
+Make sure you have installed time support for mysql or mariadb as explained [here](https://dev.mysql.com/doc/refman/5.7/en/time-zone-support.html).  In GNU/Linux you run the mysql_tzinfo_to_sql program from the commandline:
+
+`mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql`
+
+It is recommended that you install this software with Docker.
+
+Dockerfile may be found at [https://github.com/fspc/ybdb](https://github.com/fspc/ybdb), or you may pull the repository (updated infrequently).
+
+```
+docker pull bikebike/ybdb
+```
+
+## Run the docker container
+
+Publish the container's port to the host:
+
+>format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort
+
+
+```
+docker run -d -p 81:80 --name="ybdb" bikebike/ybdb
+```
+
+## How to test/develop inside the running container process 
+
+```
+sudo docker exec -it ybdb /bin/bash
+```
+
+If it produces this error:
+
+```
+rpc error: code = 13 desc = invalid header field value "oci runtime error: exec failed: container_linux.go:247: starting container process caused \"process_linux.go:75: starting setns process caused \\\"fork/exec /proc/self/exe: no such file or directory\\\"\"\n"
+```
+
+then do this before attempting again:
+
+
+```
+docker stop ybdb
+docker start ybdb
+```
