-
-Configuration options for the WireGuard backend, which manages the WireGuard interfaces and peers.
-The current MikroTik backend is in **BETA** and may not support all features.
-
-### `default`
-- **Default:** `local`
-- **Description:** The default backend to use for managing WireGuard interfaces. 
-  Valid options are: `local`, or other backend id's configured in the `mikrotik` section.
-
-### `ignored_local_interfaces`
-- **Default:** *(empty)*
-- **Description:** A list of interface names to exclude when enumerating local interfaces.
-  This is useful if you want to prevent certain interfaces from being imported from the local system.
-
-### Mikrotik
-
-The `mikrotik` array contains a list of MikroTik backend definitions. Each entry describes how to connect to a MikroTik RouterOS instance that hosts WireGuard interfaces.
-
-Below are the properties for each entry inside `backend.mikrotik`:
-
-#### `id`
-- **Default:** *(empty)*
-- **Description:** A unique identifier for this backend. 
-  This value can be referenced by `backend.default` to use this backend as default.
-  The identifier must be unique across all backends and must not use the reserved keyword `local`.
-
-#### `display_name`
-- **Default:** *(empty)*
-- **Description:** A human-friendly display name for this backend. If omitted, the `id` will be used as the display name.
-
-#### `api_url`
-- **Default:** *(empty)*
-- **Description:** Base URL of the MikroTik REST API, including scheme and path, e.g., `https://10.10.10.10:8729/rest`.
-
-#### `api_user`
-- **Default:** *(empty)*
-- **Description:** Username for authenticating against the MikroTik API.
-  Ensure that the user has sufficient permissions to manage WireGuard interfaces and peers.
-
-#### `api_password`
-- **Default:** *(empty)*
-- **Description:** Password for the specified API user.
-
-#### `api_verify_tls`
-- **Default:** `false`
-- **Description:** Whether to verify the TLS certificate of the MikroTik API endpoint. Set to `false` to allow self-signed certificates (not recommended for production).
-
-#### `api_timeout`
-- **Default:** `30s`
-- **Description:** Timeout for API requests to the MikroTik device. Uses Go duration format (e.g., `10s`, `1m`). If omitted, a default of 30 seconds is used.
-
-#### `concurrency`
-- **Default:** `5`
-- **Description:** Maximum number of concurrent API requests the backend will issue when enumerating interfaces and their details. If `0` or negative, a sane default of `5` is used.
-
-#### `ignored_interfaces`
-- **Default:** *(empty)*
-- **Description:** A list of interface names to exclude during interface enumeration.
-  This is useful if you want to prevent specific interfaces from being imported from the MikroTik device.
-
-#### `debug`
-- **Default:** `false`
-- **Description:** Enable verbose debug logging for the MikroTik backend.
-
-For more details on configuring the MikroTik backend, see the [Backends](../usage/backends.md) documentation.

-# Backends
-
-WireGuard Portal can manage WireGuard interfaces and peers on different backends. 
-Each backend represents a system where interfaces actually live. 
-You can register multiple backends and choose which one to use per interface. 
-A global default backend determines where newly created interfaces go (unless you explicitly choose another in the UI).
-
-**Supported backends:**
-- **Local** (default): Manages interfaces on the host running WireGuard Portal (Linux WireGuard via wgctrl). Use this when the portal should directly configure wg devices on the same server.
-- **MikroTik** RouterOS (_beta_): Manages interfaces and peers on MikroTik devices via the RouterOS REST API. Use this to control WG interfaces on RouterOS v7+.
-
-How backend selection works:
-- The default backend is configured at `backend.default` (_local_ or the id of a defined MikroTik backend). 
-  New interfaces created in the UI will use this backend by default.
-- Each interface stores its backend. You can select a different backend when creating a new interface.
-
-## Configuring MikroTik backends (RouterOS v7+)
-
-> :warning: The MikroTik backend is currently marked beta. While basic functionality is implemented, some advanced features are not yet implemented or contain bugs. Please test carefully before using in production.
-
-The MikroTik backend uses the [REST API](https://help.mikrotik.com/docs/spaces/ROS/pages/47579162/REST+API) under a base URL ending with /rest. 
-You can register one or more MikroTik devices as backends for a single WireGuard Portal instance.
-
-### Prerequisites on MikroTik:
-- RouterOS v7 with WireGuard support.
-- REST API enabled and reachable over HTTP(S). A typical base URL is https://<router-address>:8729/rest or https://<router-address>/rest depending on your service setup.
-- A dedicated RouterOS user with the following group permissions:
-  - **api** (for logging in via REST API)
-  - **rest-api** (for logging in via REST API)
-  - **read** (to read interface and peer data)
-  - **write** (to create/update interfaces and peers)
-  - **test** (to perform ping checks)
-  - **sensitive** (to read private keys)
-- TLS certificate on the device is recommended. If you use a self-signed certificate during testing, set `api_verify_tls`: _false_ in wg-portal (not recommended for production).
-
-Example WireGuard Portal configuration (config/config.yaml):
-
-```yaml
-backend:
-  # default backend decides where new interfaces are created
-  default: mikrotik-prod
-
-  mikrotik:
-    - id: mikrotik-prod              # unique id, not "local"
-      display_name: RouterOS RB5009  # optional nice name
-      api_url: https://10.10.10.10/rest
-      api_user: wgportal
-      api_password: a-super-secret-password
-      api_verify_tls: true         # set to false only if using self-signed during testing
-      api_timeout: 30s             # maximum request duration
-      concurrency: 5               # limit parallel REST calls to device
-      debug: false                 # verbose logging for this backend
-```
-
-### Known limitations:
-- The MikroTik backend is still in beta. Some features may not work as expected.
-- Not all WireGuard Portal features are supported yet (e.g., no support for interface hooks)
