+To import strategies and toggles from a file (called `configuration.yml` in the examples below), either
+- use the `importFile` parameter to point to the file (you can also passed this into the `unleash.start()` entry point)
+   ``` shell
+   unleash-server --databaseUrl [...] \
+   	       --importFile configuration.yml
+   ```
 
-``` shell
-unleash-server --databaseUrl [...] \
-	       --importFile configuration.yml
-```
+- set the `IMPORT_FILE` environment variable to the path of the file before starting Unleash
 
-To clean the database before import (all strategies and features will be removed), add the `dropBeforeImport` flag:
+   ``` shell
+   IMPORT_FILE=configuration.yml
+   ```

 :::caution
 You should never use this in production environments.

-### Import files via environment variables
-
-Use the `IMPORT_FILE` environment variable to set the path to the import file. For instance:
-
-``` shell
-IMPORT_FILE=configuration.yml
-```
-
-To clean the database before import, set the `IMPORT_DROP_BEFORE_IMPORT` (note the leading `IMPORT_`) variable to `true`, `t`, or `1`. The variable is case-sensitive.
-
-``` shell
-IMPORT_DROP_BEFORE_IMPORT=true
-```
+To remove pre-existing feature toggles and strategies in the database before importing the new ones, either:
+- add the `dropBeforeImport` flag to the `unleash-server` command (or to `unleash.start()`)
+   ``` shell
+   unleash-server --databaseUrl [...] \
+   	       --importFile configuration.yml \
+   	       --dropBeforeImport
