+## Allow custom MAC vendor overrides 
+Issues [#169](https://github.com/aceberg/WatchYourLAN/issues/169), [#185](https://github.com/aceberg/WatchYourLAN/issues/185)
+
+WatchYourLAN is using `arp-scan`, so most of its options are available to WYL users.
+
+1. Prepare a [mac-vendor.txt](https://manpages.debian.org/testing/arp-scan/mac-vendor.5.en.html) file with additional MACs and put it in a mounted WYL directory.
+2. If you are using `IFACES` variable to define interfaces, add path to mac-vendor.txt to `ARP_ARGS`
+```yaml
+arp_args: --macfile=/data/WatchYourLAN/mac-vendor.txt
+```
+3. For interfaces defined in `ARP_STRS` add the same directly in the beginning of `ARP_STRS` string
+```yaml
+arp_strs:
+    - --macfile=/data/WatchYourLAN/mac-vendor.txt -gNx 10.144.0.1/24 -I eth0
+```
+4. **WARNING!** To see an updated vendor, you'll have to delete host and wait for the next scan.

-> **BREAKING CHANGES!** Version 2.0 is not compatible with v1.0. For now v2.0 docker images will be released under `v2` tag. It will be tagged `latest` in a few weeks (probably, in October).
+Lightweight network IP scanner with web GUI. Features:
+- Send notification when new host is found
+- Monitor hosts online/offline history
+- Keep a list of all hosts in the network
+- Send data to `InfluxDB2` or `Prometheus` to make a `Grafana` dashboard

+
+**WatchYourLAN** does not have built-in auth option. But you can use it with SSO tools like Authelia, or my simple auth app [ForAuth](https://github.com/aceberg/ForAuth).   
+Here is an example [docker-compose-auth.yml](https://github.com/aceberg/WatchYourLAN/blob/main/docker-compose-auth.yml).
+
+> :warning:  **WARNING!**   
+> Please, don't forget that WYL needs `host` network mode to work. So, WYL port will be exposed in this setup. You need to limit access to it with firewall or other measures.

+## Passing arguments to arp-scan
+
+### 1. IFACES
+
+`IFACES` is a required variable for WYL to work. It can be set through `GUI`, config file or environment variables.   
+`IFACES` is a list of network interfaces to scan, space separated. For example 
+```sh
+IFACES: "enp4s0 wlxf4ec3892dd51"
+```
+You can get a list of network interfaces by running `ip link show` or `netstat -i`.
+By default, the scan command will look like this:
+```sh
+arp-scan -glNx -I $ONE_IFACE
+```
+
+### 2. ARP_ARGS
+Setting `ARP_ARGS` is optional. It can be set through `GUI`, config file or environment variables.   
+`ARP_ARGS` is additional arguments for `arp-scan`, that will be applied for **every** one of `IFACES`. For example:
+```sh
+ARP_ARGS: "-r 1"
+```
+```sh
+arp-scan -glNx -r 1 -I $ONE_IFACE
+```
+See `man arp-scan` for all arguments available.   
+
+
+### 3. ARP_STRS for VLANs, docker0 and other complicated scans
+If `ARP_STRS` is set, it will initiate a completely separate from `IFACES` scan.   
+> [!WARNING]   
+> `ARP_STRS` can be set only through `GUI` or config file. For environment (docker-compose) see `ARP_STRS_JOINED`.   
+
+`ARP_STRS` is a list of strings. `arp-scan` will run for each of them:
+```sh
+arp-scan $ONE_STRING
+```
+Every string must contain all information you need to pass to `arp-scan`. For example:
+```sh
+arp-scan -gNx 10.0.107.0/24 -Q 107 -I eth0
+```
+Where `-Q` is a `vlan` id. **Warning:** the last element of string (`eth0` in this example) will be set as `Interface` for found hosts, so it is recommended to put interface at the end.
+
+
+Setting `ARP_STRS` from config file:
+```yaml
+arp_strs:
+    - -gNx 172.17.0.1/24 -I docker0
+    - -glNx -I virbr0
+```
+From `GUI` put one string in `Arp Strings` input field, click `Save`, then another empty string will appear.
+
+### 4. ARP_STRS_JOINED
+`ARP_STRS_JOINED` is a way to set `ARP_STRS` from ENV. It's a list of strings, comma separated, without spaces before or after comma.
+```sh
+ARP_STRS_JOINED: "-gNx 172.17.0.1/24 -I docker0,-gNx 10.0.107.0/24 -Q 107 -I eth0"
+```
+
+### 5. Examples
+vlan id 107
+```sh
+ARP_STRS_JOINED: "-gNx 10.0.107.0/24 -Q 107 -I eth0"
+```
+docker0
+```sh
+ARP_STRS_JOINED: "-gNx 172.17.0.1/24 -I docker0"
+```
