+
+#### Installation and configuration:
+Set up a directory structure as below.
+You only need the `notify_templates/notify_v2.sh` file and any notification templates you wish to enable, but there is no harm in having all of them present.
+```
+ .
+├── notify_templates/
+│   ├── notify_DSM.sh
+│   ├── notify_apprise.sh
+│   ├── notify_discord.sh
+│   ├── notify_generic.sh
+│   ├── notify_gotify.sh

+│   └── notify_v2.sh
+├── dockcheck.config
+├── dockcheck.sh
+└── urls.list         # optional
+```
+- Uncomment and set the `NOTIFY_CHANNELS=""` environment variable in `dockcheck.config` to a space separated string of your desired notification channels to enable.
+- Uncomment and set the environment variables related to the enabled notification channels. Eg. `GOTIFY_DOMAIN=""` + `GOTIFY_TOKEN=""`.
+
+It's recommended to only do configuration with variables within `dockcheck.config` and not modify `notify_templates/notify_X.sh` directly. If you wish to customize the notify templates yourself, you may copy them to your project root directory alongside the main `dockcheck.sh` (where they're also ignored by git).  
+Customizing `notify_v2.sh` is handled the same as customizing the templates, but it must be renamed to `notify.sh` within the `dockcheck.sh` root directory.  
+
+
+#### Snooze feature:
+Configure to receive scheduled notifications only if they're new since the last notification - within a set time frame.
+
+**Example:** *Dockcheck is scheduled to run every hour. You will receive an update notification within an hour of availability.*  
+**Snooze enabled:** You will not receive a repeated notification about an already notified update within the snooze duration.  
+**Snooze disabled:** You will receive additional (possibly repeated) notifications every hour.  
+
+To enable snooze uncomment the `SNOOZE_SECONDS` variable in your `dockcheck.config` and set it to the number of seconds you wish to prevent duplicate alerts.  
+Snooze is split into three categories; container updates, `dockcheck.sh` self updates and notification template updates.
+
+If an update becomes available for an item that is not snoozed, notifications will be sent and include all available updates for that item's category, even snoozed items.
+
+The actual snooze duration will be 60 seconds less than `SNOOZE_SECONDS` to account for minor scheduling or run time issues.

+#### Notification channel configuration:
+All required environment variables for each notification channel are provided in the default.config file as comments and must be uncommented and modified for your requirements.  
+For advanced users, additional functionality is available via custom configurations and environment variables.  
+Use cases - all configured in `dockcheck.config`:  
+(replace `<channel>` with the upper case name of the of the channel as listed in `NOTIFY_CHANNELS` variable, eg `TELEGRAM_SKIPSNOOZE`)
+- To bypass the snooze feature, even when enabled, add the variable `<channel>_SKIPSNOOZE` and set it to `true`.
+- To configure the channel to only send container update notifications, add the variable `<channel>_CONTAINERSONLY` and set it to `true`.
+- To send notifications even when there are no updates available, add the variable `<channel>_ALLOWEMPTY`  and set it to `true`.
+- To use another notification output format, add the variable `<channel>_OUTPUT` and set it to `csv`, `json`, or `text`. If unset or set to an invalid value, defaults to `text`.
+- To send multiple notifications using the same notification template:
+  - Strings in the `NOTIFY_CHANNELS` list are now treated as unique names and do not necessarily refer to the notification template that will be called, though they do by default.
+  - Add another notification channel to `NOTIFY_CHANNELS` in `dockcheck.config`. The name can contain upper and lower case letters, numbers and underscores, but can't start with a number.
+  - Add the variable `<channel>_TEMPLATE` to `dockcheck.config` where `<channel>` is the name of the channel added above and set the value to an available notification template script (`slack`, `apprise`, `gotify`, etc.)
+  - Add all other environment variables required for the chosen template to function with `<channel>` in upper case as the prefix rather than the template name.
+    - For example, if `<channel>` is `mynotification` and the template configured is `slack`, you would need to set `MYNOTIFICATION_CHANNEL_ID` and `MYNOTIFICATION_ACCESS_TOKEN`.

+## 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

+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.
