+After you deploy OceanBase Deployer (OBD), you can run the `obd demo` command to deploy and start OceanBase Database on a single local server. Make sure the following prerequisites are met:
 
-- You have logged on as the root user.
-- Ports `2882` and `2883` are available.
-- Your server has at least 8 GB of memory.
-- Your server has at least 2 CPU cores.

+- At least 6 GB of memory is available on the server.
 
-> **NOTE:** For the convenience of using root here, OBD and OceanBase database do not have any restrictions on running users. We do not recommend that you use root in production.

+A: There are two ways to update your OBD, which you can choose from depending on your situation:
 
 + If your machine can connect to the public network or have the RPM package for the updated OBD in the mirror you configured, you can directly use the `obd update` command to update the OBD. When you finish with the update, use the `obd --version` command to check the version of OBD and confirm whether the update is successful.
 + If your machine cannot connect to the public network and there is no RPM package for the updated OBD in the mirror you configured. Please add the RPM package that used to update OBD to the local mirror via `obd mirror clone` command first, and then use the `obd update` command to update the OBD.
