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

+This web interface makes **heavy use of TeamSpeak 3 server query commands**. Please ensure that you _increase query

-###### I always get `TSException: Error: host isn't a ts3 instance!` when selecting a server.
+Please read the next sections carefully.
-You probably got query banned from your server. You need to properly define your `whitelist.txt` file and include it in 
-your TeamSpeak application.
 
-## Configuration
+## Setup
-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.

-* Logs are saved in `/var/www/html/application/log` for docker containers. You should create a volume

-### Usage with docker-compose
+* 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`

+* 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`.
 
+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

+docker run -d --rm --name ts3web_creator -v ts3web-vol:/mnt alpine tail -f /dev/null
-For testing purposes, change `- 127.0.0.1:8181:80` to `- 8181:80`. The web interface will then be available under 
+docker exec -it ts3web_creator sh
-`public-server-ip:8181`. This is **not recommended**! Secure your setup properly via reverse proxy and SSL!
 
-### Usage as single docker container
+# inside the container, edit the env by copying the example to the docker volume mount path at /data/env
-* Copy `env.example` to `env` and adjust to your needs. It's recommended to make it persistent outside of the container.
+cp /var/www/html/application/config/env /data/env
-* 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
+# edit the env file to your liking
-**Prerequisite**: `php`, `composer` and probably `php-fpm` installed on the server.
+#
+# the teamspeak_host should point to your public ip address and must be whitelisted inside the teamspeak server itself
+vi env
 
-To install:
+# create necessary directories and set permissions
-* Clone repository
+mkdir -p /data/log
-* Change directory to project home
+touch /data/log/application.log
-* Execute `composer install`
+mkdir -p /data/snapshots
-* `composer install`
+chown -R 65534:65534 /data
-* 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))
 
-To upgrade:
+# exit the container
-* Change directory to project home
+exit
-* `git pull`
-* `composer update`
-
-### Web server setup
-* Example `nginx.conf` for **standalone** deployment without SSL:
 
+# 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.

+## 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.

 ## Development
 
+Contributions are welcome!
+
 ### Release
+
 * Set a date in the `CHANGELOG.md` file
 * Remove `SNAPSHOT` from the version in `Constants.php`
 * Build the docker image from the project
     * if necessary, add GitHub access token to let composer pull dependencies within the image correctly:
       add `&& composer config --global --auth github-oauth.github.com <token> \` before the `composer install` command,
       where `<token>` can be retrieved from [GitHub settings](https://github.com/settings/tokens)
-    * execute `docker build -t varakh/ts3web:latest -t varakh/ts3web:<releaseTag> -f docker/Dockerfile .` to build
+    * execute `sudo docker build --no-cache -t varakh/ts3web:latest .` to build
     * publish it
 * Tag the release git commit and create a new release in the VCS web interface

 ### 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`.
