+# pyp2spec
+
+This project is a thought descendant of [specfile_generator](https://github.com/frenzymadness/specfile_generator).
+
+It aims to generate working Fedora RPM spec file for Python projects.
+The produced spec files must be compliant with the current [Python Packaging Guidelines](https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/) (in effect since 2021).
+It utilizes the benefits of [pyproject-rpm-macros](https://src.fedoraproject.org/rpms/pyproject-rpm-macros).
+
+It is under development.
+
+## What it will do
+
+The project will consist of two parts:
+- *pyp2conf*: gathers of all the necessary information to produce a spec file and stores it in a configuration file - **not available yet**
+- *conf2spec*: produces working spec file using all the information from configuration file - **a limited set of functionalities is available**
+
+## Configuration file specification
+
+Configuration data is stored in a TOML file.
+
+TBD
+
+## How to run
+
+To run whatever this project offers at this point, install to your virtual environment the dependencies from `requirements.txt`:
+
+```
+python -m pip install -r requirements.txt
+```
+
+Until the configuration file specification is set, you can use the test files to run the script:
+```
+python conf2spec.py -f tests/pyp2spec_click/pyp2spec_click.conf
+```
+
+### Tests
+
+To run the tests, install pytest & run it:
+
+```
+python -m pip install pytest
+python -m pytest
+```
