 |----------------|----------------------------------------------|---------|
-|`USER_ID`| ID of the user the application runs as.  See [User/Group IDs](#usergroup-ids) to better understand when this should be set. | `1000` |
-|`GROUP_ID`| ID of the group the application runs as.  See [User/Group IDs](#usergroup-ids) to better understand when this should be set. | `1000` |
+|`USER_ID`| ID of the user the application runs as. See [User/Group IDs](#usergroup-ids) to better understand when this should be set. | `1000` |
+|`GROUP_ID`| ID of the group the application runs as. See [User/Group IDs](#usergroup-ids) to better understand when this should be set. | `1000` |
 |`SUP_GROUP_IDS`| Comma-separated list of supplementary group IDs of the application. | (no value) |
-|`UMASK`| Mask that controls how permissions are set for newly created files and folders.  The value of the mask is in octal notation.  By default, the default umask value is `0022`, meaning that newly created files and folders are readable by everyone, but only writable by the owner.  See the online umask calculator at http://wintelguy.com/umask-calc.pl. | `0022` |
-|`LANG`| Set the [locale](https://en.wikipedia.org/wiki/Locale_(computer_software)), which defines the application's language, **if supported**.  Format of the locale is `language[_territory][.codeset]`, where language is an [ISO 639 language code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes), territory is an [ISO 3166 country code](https://en.wikipedia.org/wiki/ISO_3166-1#Current_codes) and codeset is a character set, like `UTF-8`.  For example, Australian English using the UTF-8 encoding is `en_AU.UTF-8`. | `en_US.UTF-8` |
-|`TZ`| [TimeZone](http://en.wikipedia.org/wiki/List_of_tz_database_time_zones) used by the container.  Timezone can also be set by mapping `/etc/localtime` between the host and the container. | `Etc/UTC` |
+|`UMASK`| Mask that controls how permissions are set for newly created files and folders. The value of the mask is in octal notation. By default, the default umask value is `0022`, meaning that newly created files and folders are readable by everyone, but only writable by the owner.

 |`KEEP_APP_RUNNING`| When set to `1`, the application will be automatically restarted when it crashes or terminates. | `0` |
-|`APP_NICENESS`| Priority at which the application should run.  A niceness value of -20 is the highest priority and 19 is the lowest priority.  The default niceness value is 0.  **NOTE**: A negative niceness (priority increase) requires additional permissions.  In this case, the container should be run with the docker option `--cap-add=SYS_NICE`. | `0` |
-|`INSTALL_PACKAGES`| Space-separated list of packages to install during the startup of the container.  List of available packages can be found at https://pkgs.alpinelinux.org.  **ATTENTION**: Container functionality can be affected when installing a package that overrides existing container files (e.g. binaries). | (no value) |
