 ### Optional
 
+- `default` (Boolean) Whether this preset should be selected by default when creating a workspace. Only one preset per template can be marked as default.
 - `parameters` (Map of String) Workspace parameters that will be set by the workspace preset. For simple templates that only need prebuilds, you may define a preset with zero parameters. Because workspace parameters may change between Coder template versions, preset parameters are allowed to define values for parameters that do not exist in the current template version.
 - `prebuilds` (Block Set, Max: 1) Configuration for prebuilt workspaces associated with this preset. Coder will maintain a pool of standby workspaces based on this configuration. When a user creates a workspace using this preset, they are assigned a prebuilt workspace instead of waiting for a new one to build. See prebuilt workspace documentation [here](https://coder.com/docs/admin/templates/extending-templates/prebuilt-workspaces.md) (see [below for nested schema](#nestedblock--prebuilds))

 ### Optional
 
-- `cron` (String) The cron schedule to run the script on. This is a cron expression.
+- `cron` (String) The cron schedule to run the script on. This uses a 6-field cron expression format: `seconds minutes hours day-of-month month day-of-week`. Note that this differs from the standard Unix 5-field format by including seconds as the first field. Examples: `"0 0 22 * * *"` (daily at 10 PM), `"0 */5 * * * *"` (every 5 minutes), `"30 0 9 * * 1-5"` (weekdays at 9:30 AM).
 - `icon` (String) A URL to an icon that will display in the dashboard. View built-in icons [here](https://github.com/coder/coder/tree/main/site/static/icon). Use a built-in icon with `"${data.coder_workspace.me.access_url}/icon/<path>"`.
 - `log_path` (String) The path of a file to write the logs to. If relative, it will be appended to tmp.
 - `run_on_start` (Boolean) This option defines whether or not the script should run when the agent starts. The script should exit when it is done to signal that the agent is ready.
