+TeamSpeak has a detailed interface for permissions and uploading files, therefore the following features are not 
 supported:
 
 * uploading files (only viewing and deleting, use the official client for uploading)
 * editing permissions (only viewing, use the client for editing)
 
-## READ BEFORE USING
+## F.A.Q
 
-This web interface makes **heavy use of TeamSpeak 3 server query commands**. Please ensure that you _increase query
-limits_ and whitelist the requesting IP address to a `whitelist.txt` when in a docker environment (see below).
+###### There are lots of TeamSpeak 3 web interfaces out. Why should I pick ts3web? 
+Free, simple, stateless, easy to extend, standard bootstrap theme.
 
-Please read the next sections carefully.
+###### I always get `TSException: Error: host isn't a ts3 instance!` when selecting a server.
+You probably got query banned from your server. You need to properly define your `whitelist.txt` file and include it in 
+your TeamSpeak application.
 
-## Setup
+## Configuration
+The main configuration file is the `env` file located in `config/`. There's an example file called `env.example` 
+which you **need** to copy to `config/env`. Defaults will assume you're running your TeamSpeak server on `localhost` with 
+default port. Docker deployments can and *should* host bind this file into the container directly and just maintain the 
+`env` file.
 
-_ts3web_ can be deployed natively or via docker. It's recommended to use docker with docker-compose. Those steps are
-outlined below.
+## Deployment
+The application can be deployed in different ways. See below for more information. For each deployment type a running 
+TeamSpeak 3 instance is a prerequisite (except for the `docker-compose.yml` type which will start also the server if 
+needed).
 
-### docker-compose
+### Exposed volumes on docker images
+* Snapshots are saved in `/var/www/html/application/data/snapshots`. You should create a volume for this location if 
+you're using docker as deployment type.
+* Logs are saved in `/var/www/html/application/log` for docker containers. You should create a volume 
+for this location if you're using docker as deployment type. You should also create the log file `application.log` already.
 
-General remarks:
+**Important**: Ensure that host binds have permissions set up properly. The user which is used in the docker container 
+is `www-data` with id `82`. If, e.g. logs are host bound, then execute `chown -R 82:82 host/path/to/log`. 
+The same holds true for snapshots.
 
-* By default, `/var/www/html/application/config/env` is used for bootstrapping necessary configuration, can be set to another parent directory with `ENV_DIR` in docker environment variable, e.g., `ENV_DIR=/data`
-* By default, `/var/www/html/application/data/snapshots` is used for storing snapshots, path can be changed in the `env` file with `snapshot_dir`
-* By default, `/var/www/html/application/log` is used for storing and reading logs, path can be changed in the `env` file with `log_dir`
-* Other `env` configuration values are outlined in the [env.example](./config/env.example) file which is also present in the default docker image.
+### Usage with docker-compose
+The recommended way is to use docker-compose. The `network_mode = "host"` is required in order to show correct IP 
+addresses of connected TeamSpeak users.
 
-It's recommended to use the `network=HOST` option for the docker setup, and it will be the only example in this `README` file.
+1. The web interface will not be able to use `localhost` as TeamSpeak 3 server address because it's not available in a 
+docker container when _not_ using the `host` network. Thus the`whitelist.txt` **must** include your public TeamSpeak 3 
+server IP for this example setup.
+2. The public address also has to match the environment variable `teamspeak_host=your-public-address` within
+the `env` file referenced in the example `docker-compose`.
 
-Let's create the docker volumes first. You could also use automatically generated ones by the `docker-compose` file, you
-would need to remove the `external: true` in the `volumes` section of the `docker-compose.yml` then.
-
-Create the external volumes:
-
-```shell
-docker volume create ts3-vol
-docker volume create ts3web-vol
 ```
-
-Paste the example `docker-compose.yml` into a file on your machine:
-
-```yaml
 version: '2.1'
 networks:
   teamspeak:
     external: false
-
 services:
   app:

-      # volume needs to contain the env file!
-      - ENV_DIR=/data
+      - ./env:/var/www/html/application/config/env

 ```
 
-Let's populate our docker volumes **before** we start!
+Now execute `docker-compose up -d` to start those containers. If you like to update, do `docker-compose down`, 
+`docker-compose pull` and then `docker-compose up -d` again.
 
-```shell
-docker run -d --rm --name ts3web_creator -v ts3web-vol:/mnt alpine tail -f /dev/null
-docker exec -it ts3web_creator sh
+Your TeamSpeak 3 Server will be available under `public-server-ip:9987`. The web interface will be available on
+`127.0.0.1:8181`. You need to add a reverse proxy and probably you also want SSL configured if you expose it via domain.
+For testing purposes, change `- 127.0.0.1:8181:80` to `- 8181:80`. The web interface will then be available under 
+`public-server-ip:8181`. This is **not recommended**! Secure your setup properly via reverse proxy and SSL!
 
-# inside the container, edit the env by copying the example to the docker volume mount path at /data/env
-cp /var/www/html/application/config/env /data/env
-
-# edit the env file to your liking
-#
-# the teamspeak_host should point to your public ip address and must be whitelisted inside the teamspeak server itself
-vi env
-
-# create necessary directories and set permissions
-mkdir -p /data/log
-touch /data/log/application.log
-mkdir -p /data/snapshots
-chown -R 65534:65534 /data
-
-# exit the container
-exit
-
-# on the host system, stop the creator container
-docker stop ts3web_creator
-```
-
-Let's populate the teamspeak container with a proper `whitelist.txt` file. See [ensure that you're whitelisting the IP from which the webinterface will issue commands](#whitelisttextfile).
-
-```shell
-docker run -d --rm --name ts3_creator -v ts3-vol:/mnt alpine tail -f /dev/null
-docker exec -it ts3_creator sh
-
-# edit the whitelist.txt file at /var/ts3server/whitelist.txt
-# it should contain the following entries
-#
-# 127.0.0.1
-# ::1
-# your-public-ip
-#
-vi /var/ts3server/whitelist.txt
-
-# exit the container
-exit
-
-# on the host system, stop the creator container
-docker stop ts3_creator
-```
-
-Maybe you like to copy valid license files into the `ts3-vol` docker volume before stopping.
-
-_Finally_, start the stack with `docker-compose up -d`. Please see the **Reverse proxy** section for a nginx example.
-
-### Reverse proxy
-
-Here's an example on how to configure a reverse proxy for the web interface docker container
-
-```shell
-root   .../public;
-index index.php;   
-
-# enable and setup if you have a certificate (highly recommended)
-#ssl on;
-#ssl_certificate fullchain.pem;
-#ssl_certificate_key privkey.pem; 
-
-rewrite_log on;
-
-location / {
-try_files $uri $uri/ @ee;
-}
-
-location @ee {
-rewrite ^(.*) /index.php?$1 last;
-}
-
-# php fpm
-location ~ \.php$ {
-fastcgi_split_path_info ^(.+\.php)(/.+)$;
-fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
-include        fastcgi_params;
-}
-```
-
-## Native application
+### Usage as single docker container
+* Copy `env.example` to `env` and adjust to your needs. It's recommended to make it persistent outside of the container.
+* Create a container with the image, e.g. `docker run --name teamspeak_web -v ./env:/var/www/html/application/config/env -p 8181:80 varakh/ts3web:latest`. 
+* Make sure that if TeamSpeak and ts3web share the same docker instance and that they should be put into one network and the subnet **needs be added to teamspeak's query whitelist**.
+* Point your browser to `8181` to see the web interface. 
 
+### Usage as native application
 **Prerequisite**: `php`, `composer` and probably `php-fpm` installed on the server.
 
-### Install
-
+To install:
 * Clone repository
 * Change directory to project home
 * Execute `composer install`
 * `composer install`
 * Do the configuration by coping the `env.example` file (see information above)
-* Use a web server _or_ run directly via the embedded PHP server: `php -S localhost:8080 -t public public/index.php`.
-* Point your browser to [localhost:8080](http://localhost:8080)
-* Apply any [whitelist.txt](#whitelist-text-file) changes if you configured `teamspeak_host` differently
-  than `localhost`
-
-### Upgrade
+* Use a web server or run directly via PHP server: `php -S localhost:8080 -t public public/index.php` (point browser to [localhost:8080](http://localhost:8080))
 
+To upgrade:
 * Change directory to project home
 * `git pull`
 * `composer update`
 
-## Troubleshooting / F.A.Q
+### Web server setup
+* Example `nginx.conf` for **standalone** deployment without SSL:
 
-<a name="flood"></a>
-### How to overcome server query limit?
+    ```  
+    root   .../public;
+    index index.php;    
+    
+    rewrite_log on;
+    
+    location / {

+    ```
 
-You might get one of these messages:
-
-> I always get `flood client` message when clicking anywhere in the web interface.
-
-The web UI uses query commands _a lot_! When your instance is up and running, you should be able to change the following
-setting, e.g. directly in your database (MySQL or sqlite).
-
-```ini
-serverinstance_serverquery_flood_commands = 9999
-serverinstance_serverquery_max_connections_per_ip = 999
-serverinstance_serverquery_flood_time = 1
-```
-
-<a name="whitelist"></a>
-> I always get `TSException: Error: host isn't a ts3 instance!` when selecting a server.
-
-You're probably on a docker environment and the TeamSpeak server is queried through the web UI which
-resides behind a web server, so the TeamSpeak server thinks that the _remote web server IP address_ invokes the query
-commands and thus blacklists it.
-
-You need define an exception for you server's IP in a [`whitelist.txt`](#whitelisttextfile) file and include it in
-your TeamSpeak application.
-
-You can also add the desired IP to `query_ip_allowlist.txt` and `query_ip_whitelist.txt` within the TeamSpeak 3 Server
-data directory.
-
-<a name="dockerperms"></a>
-### I always get `no write permissions` or something similar when trying to save snapshots or when a log entry is created.
-
-This probably happens when you're in the docker setup. Ensure that host binds have permissions set up properly and also files inside any
-docker volume has the correct permissions. The user which is used in the docker container is `nobody` with id `65534`.
-
-Change owner permissions recursively with `chown -R 65534:65534 /path/to/dir`.

-### What's a whitelist.txt and why do I need it?
-
-The following illustrates a valid `whitelist.txt` file which can be used for the above `docker-compose` setups. You need
-to replace `your-public-ip` with the TeamSpeak's public IP address if required or remove the fixed internal docker IP if
-you're on 'host' mode.

+* Example `nginx.conf` as **reverse proxy** with SSL:
+    
+    ```
+    server {
+        listen      443 ssl http2;
+        server_name teamspeak.domain.tld;
+      
+        ssl on;
+        ssl_certificate fullchain.pem;
+        ssl_certificate_key privkey.pem;
+    
+        location / {
+            proxy_pass http://localhost:8181;
+            proxy_set_header X-Real-IP $remote_addr;
+            proxy_set_header Host $host;
+            proxy_set_header X-Forwarded-For $remote_addr;
+        }
