 ## :bell: Changelog
 
-- **v0.6.0**: Refactored a lot of code, cleaner logic and syntax, safer variables.
+- **v0.6.4**: Restructured the update process - first pulls all updates, then recreates all containers.
-    - Safer bash options with `set -euo pipefail`, `shopt -s nullglob` and `failglob`.
+    - Added logic to skip update check on non-compose containers (unless `-r` option).
-    - Added a `default.conf` for user settings - persistent through updates.
+    - Added option `-F` to revert to `compose up -d <ContainerName>` targeting specific container and not the stack.
-    - Added `notify_slack.sh` template for slack curl api.
+        - Also added corresponding label and config-option.
-- **v0.5.8**: Added version checks to all templates and a notification if a new template is released.
+    - Added markdown formatting to `notify_ntfy-sh.sh` template.
-- **v0.5.7**: Rewritten templates - now with a function to notify when there's a new Dockcheck release.
+- **v0.6.3**: Some fixes and changes:
-    - Manually migrate your current `notify.sh` settings to a new template for new functionality.
+    - Stops when a container recreation (compose up -d) fails, also `up`s the whole stack now.
-- **v0.5.6.1**: Async xargs hotfix - due to errors `failed to request manifest head ... context canceled`
+    - `-M`, Markdown format url-releasenotes in notification (requires template rework, look at gotify!)
-    - Defaulted subprocess to 1 with `MaxAsync=1`, increase to find a stable value in your environment.
+    - Added [addons/DSM/README.md](./addons/DSM/README.md) for more info Synology DSM info.
-    - Added `-x N` option to pass `MaxAsync` value at runtime.
+    - Permission checks - graceful exit if no docker permissions + checking if root for pkg-manager.
-    - To disable xargs `-P` flag (max processes) all together, set `MaxAsync` to 0.
+- **v0.6.2**: Style and colour changes, prometheus hotfix, new options:
-- **v0.5.6.0**: Heavily improved performance due to async checking for updates.
+    - `-u`, Allow auto self update of dockcheck.sh
+    - `-I`, Print container release URLs in the CLI "choose update" list. (please contribute to `urls.list`)
+    - Extras: `-m`, Monochrome mode now hides the progress bar.
+- **v0.6.1**: Hotfixes: (try removing set+shopt+shopt if debugging more errors)
+    - xargs/pipefail, removed `-set -e` bash option for now.
+    - unbound variables fixed (hopefully)
+    - dependency installer from pkgmanager rewritten

+## Using Dockcheck in DSM
+Dockcheck cannot directly update containers managed in the Container Manager GUI, but it can still be used to notify you of containers with updates available. There are two ways to be notified, each with their own caveats:
+
+1. Enabling email notifications within the Task Scheduler (_step 6i below_) will send an email that includes the entire script as run. This will not include the `urls.list` links to release notes, but it will show a full list of containers checked, up to date, and needing updates (following the args included in the scheduled task).
+2. The [DSM notification template](https://github.com/mag37/dockcheck/blob/main/notify_templates/notify_DSM.sh) will enable Dockcheck to directly send an email when using the `-i` flag. This is most useful when paired with an accurate [urls.list](https://github.com/mag37/dockcheck/blob/next063/notify_templates/urls.list) file, and results in a neat succinct email notification of only containers to be updated.
+
+This is a user preference, and both notifications are not necessary. However, regardless of the notification method, it is necessary to set up a scheduled task to run Dockcheck at a set interval (otherwise it will only run when manually triggered).
+
+
+## Automate Dockcheck with DSM Task Scheduler:
+
+1. Open Control Panel and navigate to Task Scheduler
+2. Create a Scheduled Task > User-defined script
+3. Task Name: Dockcheck
+4. User: root
+5. Schedule: _User Preference_
+6. Task Settings:
+    1. ✔  Send run details by email (include preferred email) _This is the optional step as described above)_
+    2. User-defined script: `export HOME=/root && cd /path/to/dockcheck && ./dockcheck.sh -n -i -I ` _or other custom args_
+8. Click OK, accept warning message
+
+
+## Set up the DSM Notification template
+
+Copy the [dockcheck/notify_templates/notify_DSM.sh](https://github.com/mag37/dockcheck/blob/main/notify_templates/notify_DSM.sh) to the same directory as where you keep `dockcheck.sh`.  
+Use as is (uses your default notification email setting) or edit and override manually.
