+It's possible to directly specify environment variables in the unit file in two ways:
 
-If you want to maintain environment settings separately see the subsections below.
+- Using an `Environment` directive in the `[Service]` block.
+- Using the `-e` option of `docker`. In this case, you can omit the `--env` option shown in the example above.
 
 To verify that your environment variables are set correctly, check the output of `systemctl show bitwarden.service`
 for an `Environment` line.
 
-##### Using a service subdirectory
-
-This is a distribution-independent directory natively recognised by systemd.
-
-As root, create the directory `/etc/systemd/system/bitwarden.service.d`.
-
-In this directory, create a `local.conf` file, which will contain any environment variables the service requires.
-The contents of the file should be of the form:
-
-```ini
-[Service]
-Environment="Key=Value"
-```
-
-Eseentially, systemd will merge the contents of this file with the unit file. `systemd-docker` then passes these
-to docker as `-e` options due to the `--env` option specified in the example above. An `EnvironmentFile` directive is not required in this configuration.

-##### Using EnvironmentFile
