 ### Persistent mode
 
-In comparison to ephemeral mode, persistent mode is more complicated to operate, but also more powerful.  Persistent mode uses a mounted host volume, a directory on the host machine that is exposed to the running docker container, to store all database data as well as the configuration files used for running services.  This allows you to manage and modify these files from the host system.

+Note that there is no guarantee that the organization of the files of the volume will remain consistent between releases of the image, that occur on every commit to the stellar/quickstart repository. At anytime new files may be added, old files removed, or dependencies and references between them changed. For this reason persistent mode is primarily intended for running short lived test instances for development. If consistency is required over any period of time use [image digest references] to pin to a specific build.

-### Customizing configurations
-
-To customize the configurations that both stellar-core and horizon use, you must use persistent mode.  The default configurations will be copied into the data directory upon launching a persistent mode container for the first time.  Use the diagram below to learn about the various configuration files that can be customized.
-
-```
-  /opt/stellar
-  |-- core
-  |   `-- etc
-  |       `-- stellar-core.cfg  # Stellar core config
-  |-- horizon
-  |   `-- etc
-  |       `-- horizon.env       # A shell script that exports horizon's config
-  |-- postgresql
-  |   `-- etc
-  |       |-- postgresql.conf   # Postgresql root configuration file
-  |       |-- pg_hba.conf       # Postgresql client configuration file
-  |       `-- pg_ident.conf     # Postgresql user mapping file
-  `-- supervisor
-      `-- etc
-  |       `-- supervisord.conf  # Supervisord root configuration
-```
-
-It is recommended that you stop the container before editing any of these files, then restart the container after completing your customization.
-
-*NOTE:* Be wary of editing these files.  It is possible to break the services started within this container with a bad edit.  It's recommended that you learn about managing the operations of each of the services before customizing them, as you are taking responsibility for maintaining those services going forward.

 ## Regarding user accounts
 
 Managing UIDs between a docker container and a host volume can be complicated.  At present, this image simply tries to create a UID that does not conflict with the host system by using a preset UID:  10011001.  Currently there is no way to customize this value.  All data produced in the host volume be owned by 10011001.  If this UID value is inappropriate for your infrastructure we recommend you fork this project and do a find/replace operation to change UIDs.  We may improve this story in the future if enough users request it.
