+## `materialize_instances` variable
+
+The `materialize_instances` variable is a list of objects that define the configuration for each Materialize instance.
+
+### `environmentd_extra_args`
+
+Optional list of additional command-line arguments to pass to the `environmentd` container. This can be used to override default system parameters or enable specific features.
+
+```hcl
+environmentd_extra_args = [
+  "--system-parameter-default=max_clusters=1000",
+  "--system-parameter-default=max_connections=1000",
+  "--system-parameter-default=max_tables=1000",
+]
+```
+
+These flags configure default limits for clusters, connections, and tables. You can provide any supported arguments [here](https://materialize.com/docs/sql/alter-system-set/#other-configuration-parameters).
