Release 2.26 which incorporates the following changes

- Add a ENV_DIR for docker containers to allow changing the env file location changes where the rest of the configuration is bootstrapped from
- Add log_dir and snapshot_dir in env file configuration to determine the log and snapshot directories
- Massively cleaned up README and provide better examples

+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)
 
-## F.A.Q
+## READ BEFORE USING
 
-###### There are lots of TeamSpeak 3 web interfaces out. Why should I pick ts3web? 
-Free, simple, stateless, easy to extend, standard bootstrap theme.
+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).
 
-###### 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.
+Please read the next sections carefully.
 
-## 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.
+## Setup
 
-## 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).
+_ts3web_ can be deployed natively or via docker. It's recommended to use docker with docker-compose. Those steps are
+outlined below.
 
-### 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.
+### docker-compose
 
-**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.
+General remarks:
 
-### 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.
+* 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.
 
-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`.
+It's recommended to use the `network=HOST` option for the docker setup, and it will be the only example in this `README` file.
 
+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:
     container_name: teamspeak_app
     image: teamspeak:latest
     volumes:
-      - ./app:/var/ts3server
-      - ./whitelist.txt:/whitelist.txt
-    ports:
-      - 10011:10011
-      - 30033:30033
-      - 9987:9987/udp
+      - ts3-vol:/var/ts3server
+    # ports are all public here in the HOST mode example
     environment:
       - TS3SERVER_LICENSE=accept
-      - TS3SERVER_IP_WHITELIST=/whitelist.txt
-    restart: always
+      - TS3SERVER_IP_WHITELIST=/var/ts3server/whitelist.txt
+    restart: unless-stopped
     network_mode: "host"
+
   web:
     container_name: teamspeak_web
-    image: teamspeak_web:latest
+    image: varakh/ts3web:latest
     volumes:
-      - ./env:/var/www/html/application/config/env
-      - ./snapshots:/var/www/html/application/data/snapshots
-      - ./log:/var/www/html/application/log
+      - ts3web-vol:/data
+    environment:
+      # volume needs to contain the env file!
+      - ENV_DIR=/data
     ports:
       - 127.0.0.1:8181:80
     depends_on:
       - app
-    restart: always
+    restart: unless-stopped
     networks:
       - teamspeak
+
+volumes:
+  ts3-vol:
+  ts3web-vol:
 ```
 
-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.
+Let's populate our docker volumes **before** we start!
 
-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!
+```shell
+docker run -d --rm --name ts3web_creator -v ts3web-vol:/mnt alpine tail -f /dev/null
+docker exec -it ts3web_creator sh
 
-### 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. 
+# 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 native application
 **Prerequisite**: `php`, `composer` and probably `php-fpm` installed on the server.
 
-To install:
+### 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 PHP server: `php -S localhost:8080 -t public public/index.php` (point browser to [localhost:8080](http://localhost:8080))
+* 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
 
-To upgrade:
 * Change directory to project home
 * `git pull`
 * `composer update`
 
-### Web server setup
-* Example `nginx.conf` for **standalone** deployment without SSL:
+## Troubleshooting / F.A.Q
 
-    ```  
-    root   .../public;
-    index index.php;    
-    
-    rewrite_log on;
-

-      include        fastcgi_params;
-    }
-    ```
+<a name="flood"></a>
+### How to overcome server query limit?
 
-* 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;
-        }
-    }
-    ```
+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
+```

+> 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`.
+
+<a name="whitelisttextfile"></a>
+### 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.
