-# C++ project
+# Example Python Package
 
-An example repository of an CI/CD pipeline for building, testing and deploying a C++ project.
+![Build status](https://git.astron.nl/templates/python-package/badges/main/pipeline.svg)
+![Test coverage](https://git.astron.nl/templates/python-package/badges/main/coverage.svg)
 
-## Description
+An example repository of an CI/CD pipeline for building, testing and publishing a python package.
 
-The repository can be used as a basis for new projects using C++ within ASTRON.
-The code is intended to be copied in a new repository and used as basis for the
-new project. After copying the code needs to be adjusted for the specific
-project. The template offers:
+If you find some missing functionality with regards to CI/CD, testing, linting or something else, feel free to make a merge request with the proposed changes.
 
-- CI jobs for building, testing, and generating documentation
+## How to apply this template
 
-  - A basic Docker file to be used in the CI
-  - A CMake project skeleton
-  - A Doxygen and Sphinx skeleton for documentation, combined with Breathe
-  - Formatting scripts for the code
+This templates uses `cookiecutter` which can be
 
-Note: The project is intended to be used for C++ projects without Fortran code.
-At the moment of writing there is no Fortran support for Ninja. This means the
-project needs to be changed to use `make`.
+```bash
+pip install --user cookiecutter
+```
 
-## Getting started
+Then you can create an instance of your template with:
 
-- Clone the project in the directory `$repo`
-- Install all dependencies as listed in `ci/ubuntu_22_04-base`
-- Create build directory: `mkdir build`
-- Create the project: `cmake -DBUILD_TESTING=ON -DBUILD_DOCUMENTATION=ON -B ./build -G Ninja`
-- Build the project: `ninja -C ./build`
-
-Specific targets can also be build on a case per case basis use `ninja -C ./build/ -t targets`
-to list all of them.
-
-For instance:
-- Build the documentation: `ninja -C ./build/ sphinx`
-- Run unit tests: `ninja -C ./build/ test`
-- Install the project globally: ``ninja -C ./build/ install``
-- Clean caches: `ninja -C ./build/ clean`
-
-## Contributing
-
-To contribute, please create a feature branch and a "Draft" merge request. Upon
-completion, the merge request should be marked as ready and a reviewer should be
-assigned.
+```bash
+cookiecutter https://git.astron.nl/templates/python-package.git

+# C++ project
+
+An example repository of an CI/CD pipeline for building, testing and deploying a C++ project.
+
+## Description
+
+The repository can be used as a basis for new projects using C++ within ASTRON.
+The code is intended to be copied in a new repository and used as basis for the
+new project. After copying the code needs to be adjusted for the specific
+project. The template offers:
+
+- CI jobs for building, testing, and generating documentation
+
+  - A basic Docker file to be used in the CI
+  - A CMake project skeleton
+  - A Doxygen and Sphinx skeleton for documentation, combined with Breathe
+  - Formatting scripts for the code
+
+Note: The project is intended to be used for C++ projects without Fortran code.
+At the moment of writing there is no Fortran support for Ninja. This means the
+project needs to be changed to use `make`.
+
+## Getting started
+
+- Clone the project in the directory `$repo`
+- Install all dependencies as listed in `ci/ubuntu_22_04-base`
+- Create build directory: `mkdir build`
+- Create the project: `cmake -DBUILD_TESTING=ON -DBUILD_DOCUMENTATION=ON -B ./build -G Ninja`
+- Build the project: `ninja -C ./build`
+
+Specific targets can also be build on a case per case basis use `ninja -C ./build/ -t targets`
+to list all of them.
+
+For instance:
+- Build the documentation: `ninja -C ./build/ sphinx`
+- Run unit tests: `ninja -C ./build/ test`
+- Install the project globally: ``ninja -C ./build/ install``
+- Clean caches: `ninja -C ./build/ clean`
+
+## Contributing
+
+To contribute, please create a feature branch and a "Draft" merge request. Upon
+completion, the merge request should be marked as ready and a reviewer should be
+assigned.
