-## Supported Engines
-
-This image is developed and tested against the Docker CE engine and Kubernetes exclusively.
-While it may work against different implementations, there are no guarantees about support for non-Docker engines.
-
 ## References
 
 We decided to publish this image as a simpler and more lightweight alternative because of the following requirements:
 
-- The original image is based on `ubuntu` and requires additional tools, making it heavy.
+- The original image is based on `Alpine` and requires additional tools, making it heavy.
 - This image is written in Go.
 - `arm64` and `arm/v7` architectures are supported.
 - Docker in Swarm mode is supported.

 ## Run in Scheduled mode
 
 This image can be run as CronJob in Kubernetes for a regular backup which makes deployment on Kubernetes easy as Kubernetes has CronJob resources.
-For Docker, you need to run it in scheduled mode by adding `--mode scheduled` flag and specify the periodical backup time by adding `--period "0 1 * * *"` flag.
+For Docker, you need to run it in scheduled mode by adding `--cron-expression  "* * * * *"` flag or by defining `BACKUP_CRON_EXPRESSION=0 1 * * *` environment variable.

+## Predefined schedules 
+You may use one of several pre-defined schedules in place of a cron expression.
+
+| Entry                  | Description                                | Equivalent To |

+
+### Intervals 
+You may also schedule backup task at fixed intervals, starting at the time it's added or cron is run. This is supported by formatting the cron spec like this:
+
+@every <duration>
+where "duration" is a string accepted by time.
+
+For example, "@every 1h30m10s" would indicate a schedule that activates after 1 hour, 30 minutes, 10 seconds, and then every interval after that.
