+# Using PyBOMBS on CentOS

+# Using PyBOMBS on OpenSUSE
+
+- A raw OpenSUSE is not able to run setuptools to install modules that require
+  compilation, e.g. ruamel.yaml. If `pip install pybombs` or installing PyBOMBS
+  via setup.py fails, try manually install ruamel.yaml, or install compilers
+  and Python development headers manually before starting to use PyBOMBS.
