 You can specify the payload compress type with `--payload-compress TYPE`: none, gzip, or zstd.
 
 For the legacy system (e.g. centos7), specify legacy compress type explicitly e.g. `--payload-compress none`.

+### Scriptlet Flags and Prog Settings
+
+Scriptlet settings can be configured via `*_script_flags` and `*_script_prog` settings.
+
+**Scriptlet Flags** 
+
+| Flag | Setting Value | Description | Example Usage |
+| ---- | ------------- | ----------- | ------- |
+| `RPMSCRIPT_FLAG_EXPAND`   | 1 | Enables macro expansion | `pre_install_script_flags = 0b001` |
+| `RPMSCRIPT_FLAG_QFORMAT`  | 2 | Enables header query format expansion | `pre_install_script_flags = 0b010` |
+| `RPMSCRIPT_FLAG_CRITICAL` | 4 | Enables critical severity for scriplet success or failure | `pre_install_script_flags = 0b100` |
+
+**Example**
+
+```toml
+pre_install_script = """
+echo preinstall
+"""
+pre_install_script_flags = 0b011 # Enables EXPAND and QFORMAT flags
+pre_install_script_prog = ["/bin/blah/bash", "-c"] # Sets the interpreter/argument settings for the scriptlet
