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

 ts3web is a free and open-source web interface for TeamSpeak 3 instances.
 
 The minimalistic approach of this application is intentional.

+Other repositories are mirrors and pull requests, issues, and planning are managed there.
 
-Questions? Here you'll hopefully get the answer. Feel free to read before starting.
+Contributions are very welcome!
-
-<a name="flood"></a>
-###### I always get `flood client` message when clicking anywhere in the web interface.
-ts3web makes heavy use of query commands. When your instance is up and running, you should be able to change
-`serverinstance_serverquery_flood_commands` to a high value, e.g. `100` and `serverinstance_serverquery_flood_time` to
-`1` which is enough.
-
-<a name="whitelist"></a>
-###### 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](#whitelisttxtexample)
-and include it in your TeamSpeak application.
-
-<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.
-The user which is used in the docker container is `nobody` with id `65534`. If, e.g. logs are host bound, then execute 
-`chown -R 65534:65534 host/path/to/log`. The same holds true for snapshots.
-
-## Configuration
-
-The main configuration file for the *web interface* 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.
-
-## Deployment
-The application can be deployed two different ways. See below for more information. For each deployment type a running 
-TeamSpeak 3 instance is a prerequisite. 
-
-In the `docker-compose.yml` [example](#dockercompose), a setup together with a teamspeak server instance is shown.
-
-### Docker
-
-#### Important. Read before setup!
-
-1. [Setup write permissions if you're using host binds](#dockerperms)
-2. [Ensure that you set `flood commands` to a higher value in your TeamSpeak](#flood).
-3. [Use a `whitelist.txt` to ensure the web interface will not be query banned](#whitelist)
-4. Be aware that the web interface will not be able to use `localhost` as TeamSpeak 3 server address because it's not 
-   available in a docker container. The public address also has to match the environment variable
-   `teamspeak_host=your-public-address` within the `env` file.
-
-<a name="dockerrun"></a>
-#### docker run
-The following section outlines a manual setup. Feel free to use the provided `docker-compose.yml` as quick setup.
-
-1. Create docker volumes for `snapshots`, `log` and `env`. Alternative is to host bind them into your containers.
-2. Create a docker network with a fixed IP range or later use host network.
-3. Depending on your setup, you need to change `teamspeak_host` of your `env` file to point either to `your IP` or to a 
-   `fixed docker IP` which your teamspeak uses. `localhost` is not valid if you're using it in docker. If you're unsure,
-   please take a look at the example `docker-compose.yml` files.
-4. Start a container using the docker image `varakh/ts3web` and provide the following bindings for volumes:
-    * `{env_file_volume|host_file}:/var/www/html/applicationconfig/env`
-    * `{snapshot_volume|host_folder}:/var/www/html/application/data/snapshots`
-    * `{log_volume|host_folder}:/var/www/html/application/log`
-5. [Ensure that you're whitelisting the IP from which the webinterface will issue commands.](#whitelist)
-6. Run the `docker run` command including your settings, volumes and networks (if any): `docker run --name teamspeak_web -v ./env:/var/www/html/application/config/env -p 8181:80 varakh/ts3web:latest`.
-
-<a name="dockercompose"></a>
-#### docker-compose
-In order for TeamSpeak to show correct IP and country flags, the `network_mode = "host"` is advised. It's also
-possible to set everything up [without using the host network mode and use fixed IPs](#withouthostmode).
-
-The examples will use host binds for volumes. Feel free to adapt the `docker-compose.yml` template and use docker volumes
-instead if you like.
-
-Ensure to [apply permissions](#dockerperms) for volumes though.

-
-```

-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.
-
-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](#reverseproxy) 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](#reverseproxy).
-
-### As native PHP application
-**Prerequisite**: `php`, `composer` and probably `php-fpm` installed on the server.
-
-#### 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](#whitelisttxtexample) changes if you configured `teamspeak_host` differently than `localhost`
-
-#### Upgrade:
-* Change directory to project home
-* `git pull`
-* `composer update`

+## READ BEFORE USING
+
+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).
+
+Please read the next sections carefully.
+
+## Setup
+
+_ts3web_ can be deployed natively or via docker. It's recommended to use docker with docker-compose. Those steps are
+outlined below.
+
+### docker-compose
+
+General remarks:
+
+* 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.
+
+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

+
+volumes:
+  ts3-vol:

+```
+
+Let's populate our docker volumes **before** we start!
+
+```shell
+docker run -d --rm --name ts3web_creator -v ts3web-vol:/mnt alpine tail -f /dev/null
+docker exec -it ts3web_creator sh
+
+# 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
+
+**Prerequisite**: `php`, `composer` and probably `php-fpm` installed on the server.
+
+### 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
+
+* Change directory to project home
+* `git pull`
+* `composer update`
+
+## Troubleshooting / F.A.Q
+
+<a name="flood"></a>
+### How to overcome server query limit?
+
+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`.
+
+<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.
+
+```
+127.0.0.1
+::1
+10.5.0.5
+your-public-ip
+```

 ### Theme
+
 Themes can be chosen in the `env` file by editing the `theme` variable. Templates are mapped to the corresponding view
 folder in `src/View/<themeName>`. `.css`, `.js` and other style files like `.ttf` or `.woff2` for fonts should be placed
 in `public/theme/<themeName>` and accessed accordingly. See an example in `src/View/boostrap4/layout.twig`.
