+## Hosts Configuration
+
+The `hosts` section defines all machines, VMs, containers, or Docker services that WoL Redirect can wake up. Each host entry may have several optional or required fields depending on its type.
+
+| Field          | Type    | Required                 | Description                                                                     |
+| -------------- | ------- | ------------------------ | ------------------------------------------------------------------------------- |
+| `ip`           | string  | Yes                      | The IP address of the host. Required for all types.                             |
+| `mac`          | string  | Required for PHYSICAL    | MAC address for Wake-on-LAN. Only needed for physical hosts.                    |
+| `id`           | string  | Required for VIRTUAL     | Identifier for virtual machines or LXCs.                                        |
+| `virtIP`       | string  | Optional                 | IP of the VM/LXC for the wake API. Defaults to `ip`.                            |
+| `startupTime`  | number  | Optional                 | Seconds to wait after starting before forwarding traffic.                       |
+| `url`          | string  | Optional                 | Override the default helper URL for this host.                                  |
+| `docker`       | object  | Required for DOCKER type | Docker-specific settings. See below.                                            |
+| `docker: true` | boolean | Optional                 | Can be set to `true` to mark a host as DOCKER type without additional settings. |
+
+## Docker Sub-Object
+
+| Field          | Type   | Required | Description                                                                                |
+| -------------- | ------ | -------- | ------------------------------------------------------------------------------------------ |
+| `queryPattern` | string | Optional | Template used to build the query for WoL Dockerized. Falls back to `ENV.woldQueryPattern`. |
+| `url`          | string | Optional | Override URL for Docker wake API. Defaults to `http://${host.ip}:${ENV.woldPort}/wake`.    |
+
+## Host Type Inference
+
+- **PHYSICAL** → has `mac` and `ip`
+- **VIRTUAL** → has `id`
+- **DOCKER** → has `docker` object or `docker: true`
+
+## Notes on Optional Overrides
+
+- `url` can override default helper URLs for PHYSICAL, VIRTUAL, or DOCKER hosts.
+- `virtIP` can override the IP used by virtual helper services.
+- `docker.queryPattern` can override the global `ENV.woldQueryPattern`.
+- `startupTime` allows per-host delay before forwarding traffic.
+- The execution order of hosts in a route determines the startup sequence.

 ## Advanced Setups
 
 WoL Redirect supports two main scenarios depending on how your services are hosted.
