+**Generate SPDX SBOM document for the installed packages.**
+
+The stage generates a Software Bill of Materials (SBOM) document
+in SPDX v2 format for the installed RPM packages. DNF4 API is used
+to retrieve the installed packages and their metadata. The SBOM
+document is saved in the specified path. If a tree is provided,
+as an input, the stage will analyze the tree instead of the
+current pipeline tree.
