+and [Deprecations](https://github.com/bakito/adguardhome-sync/wiki/Deprecations).
 
 ## Current sync features
 
+- General Settings
 - Filters
 - Rewrites
 - Services
 - Clients
+- DNS Config
+- DHCP Config
+- Theme
+
+By default, all features are enabled. Single features can be disabled in the config.
+
+### Setup of initial instances
+
+New AdGuardHome replica instances can be automatically installed if enabled via the config autoSetup. During automatic
+installation, the admin interface will be listening on port 3000 in runtime.
+
+To skip automatic setup
 
 ## Install
 
+Get from [releases](https://github.com/bakito/adguardhome-sync/releases) or install from source
+
 ```bash
-go get -u github.com/bakito/adguardhome-sync
+go install github.com/bakito/adguardhome-sync@latest
 ```
 
-## Run
+## Prerequisites
+
+Both the origin instance and replica(s) must be initially set up with AdguardHome via the AdguardHome installation wizard.
+
+## Username / Password vs. Cookie
+
+Some instances of AdGuard Home do not support basic authentication. For instance, many routers with built-in Adguard
+Home support do not. If this is the case, a valid cookie may be provided instead. If the router protects the AdGuard
+instance behind its own authentication, the cookie from an authenticated request may allow the sync to succeed.
+
+- This has been tested successfully against GL.Inet routers with AdGuard Home.
+- Note: due to the short validity of cookies, this approach is likely only suitable for one-time syncs
+
+## Run Linux/Mac
 
 ```bash
 
+export LOG_LEVEL=info
 export ORIGIN_URL=https://192.168.1.2:3000
 export ORIGIN_USERNAME=username
 export ORIGIN_PASSWORD=password
-export REPLICA_URL=http://192.168.1.3
-export REPLICA_USERNAME=username
-export REPLICA_PASSWORD=password
+# export ORIGIN_COOKIE=Origin-Cookie-Name=CCCOOOKKKIIIEEE

+### Run as Linux Service via Systemd
+
+> Verified on Ubuntu Linux 24.04
+
+Assume you have downloaded the the `adguardhome-sync` binary to `/opt/adguardhome-sync`.
+
+Create systemd service file `/opt/adguardhome-sync/adguardhome-sync.service`:
+
+```
+[Unit]
+Description = AdGuardHome Sync
+After = network.target
+
+[Service]
+ExecStart = /opt/adguardhome-sync/adguardhome-sync --config /opt/adguardhome-sync/adguardhome-sync.yaml run
+
+[Install]
+WantedBy = multi-user.target
+
+```
+
+Create a configuration file `/opt/adguardhome-sync/adguardhome-sync.yaml`, please follow [Config file](#config-file-1)
+section below for details.
+
+Install and enable service:
+
+```bash
+sudo cp /opt/adguardhome-sync/adguardhome-sync.service /etc/systemd/system/
+
+sudo systemctl enable adguardhome-sync.service
+
+sudo systemctl start adguardhome-sync.service
+
+```
+
+Then you can check the status:
+
+```bash
+sudo systemctl status adguardhome-sync.service
+
+```
+
+If web UI has been enabled in configuration (default port is 8080), can also check the status via
+`http://<server-IP>:8080`

+Also, as unraid is not known to me, I can not give any support on unraind templates.
+
+Note when running the Docker container in Unraid please remove unneeded env variables if don't needed.
+If replica2 isn't used this can cause sync errors.

+## Home Assistant AdGuard Home Add-on users
+
+To enable syncing with a Home Assistant instance using
+the [AdGuard Home Add-on](https://github.com/hassio-addons/addon-adguard-home), you will need to enable the disabled
+ports, under the Network heading
+
+![show-disabled-ports](https://github.com/user-attachments/assets/1df5f352-37a2-4508-82ec-7f270087d0b4)
+
+And then set the port of your choice for the Web interface
+
+![web-interface-port](https://github.com/user-attachments/assets/286ed030-4831-4f49-8b29-53e8802129c3)
+
+Don't forget to save and restart the add-on.
+
+Depending on your setup, you may also need to disable SSL for the add-on.
+
+The username:password required for the Home Assistant replica is the one you use to login to your instance, however it's
+recommended to setup a new local only user with minimal permissions.
+
+All credit for this method goes to [Brunty](https://github.com/brunty) who has a far
+more [detailed write up](https://brunty.me/post/replicate-adguard-home-settings-into-home-assistant-adguard-home-addon/)
+about this on his blog.
+
+## Log Level
+
+The log level can be set with the environment variable: `LOG_LEVEL`
+
+The following log levels are supported (default: info)
+
+- debug
+- info
+- warn
+- error
+
+## Log Format
+
+Default log format is `console`.
+It can be changed to `json` by setting the environment variable: `LOG_FORMAT=json`.
