+### Account IDs explode values
+
+If Account ID contains a comma the string will be exploded in simple string array. This is useful for account IDs reused with interpolation.
+
+Fo example having environment variables (or .env file) set like this:
+```bash
+export ACCOUNT_IDS="123456789012,123456789013,123456789014"
+```
+and configuring document configuration like this:
+```yaml
+name: MyDocument
+file: ./script.sh
+accountIds: 
+  - "${ACCOUNT_IDS}"
+  - "123456789015"
+```
+the deploy command will interpolate environment variables in:
+```yaml
+name: MyDocument
+file: ./script.sh
+accountIds: 
+  - "123456789012,123456789013,123456789014"
