Release 2.26 which incorporates the following changes (#1)

- 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

 # CHANGELOG
 
+## 2.2.6 - 2023/04/06
+
+_Quick update for an outdated application to make it more useful for docker setups. Keep in mind that PHP 7.4 which is used by ts3web is still EOL!_
+
+* Made it possible to use environment variable to define location of bootstrapping `env` file in docker containers (natively, set php-fpm `ENV[]` properly!)
+    * `ENV_DIR`: location of the **PARENT** folder which has the `env` file inside
+    * Falls back to application `$appDir/config/env` file if not set
+* Added new `env` file variables to easily configure
+    * `log_dir`: location of the log dir, _without trailing slash_
+    * `snapshot_dir` location of the snapshots dir, _without trailing slash_
+
 ## 2.2.5 - 2022/12/17
 * Updated `Dockerfile` (as long as alpine 3.15 shipping PHP7 is kept updated, `ts3web` docker images are kept)
 * Updated some symfony dependencies

+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
 
 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 FAQ section carefully!
+Please read the next sections carefully.
 
-## F.A.Q
+## 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
+version: '2.1'
+networks:
+  teamspeak:
+    external: false
+
+services:
+  app:
+    container_name: teamspeak_app
+    image: teamspeak:latest
+    volumes:
+      - ts3-vol:/var/ts3server
+    # ports are all public here in the HOST mode example
+    environment:
+      - TS3SERVER_LICENSE=accept
+      - TS3SERVER_IP_WHITELIST=/var/ts3server/whitelist.txt
+    restart: unless-stopped
+    network_mode: "host"
+
+  web:
+    container_name: teamspeak_web
+    image: varakh/ts3web:latest
+    volumes:
+      - 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: unless-stopped
+    networks:
+      - teamspeak
+
+volumes:
+  ts3-vol:
+  ts3web-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`

-#### docker standalone
-
-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-text-file)
-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`
-   .
-
-#### 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.
-
-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](#i-always-get-no-write-permissions-or-something-similar-when-trying-to-save-snapshots-or-when-a-log-entry-is-created) for volumes though.
