+
+## Running tests
+
+You'll need to install Python >= 3.9 and pip to setup the test environment.
+We use pipenv to execute the tests.
+
+Start with the following command in the folder where this README is located:
+`pip install pipenv --user`
+
+Finally, you can run the tests as follows:
+
+- To check the markdown run: `pipenv run test-docs`
+- To check the fiboa schema run: `pipenv run test-schema`
+- To check the examples run:
+  - `pipenv run test-geojson` for GeoJSON
+  - `pipenv run test-geoparquet` for GeoParquet
+- To create a GeoParquet from the GeoJSON examples: `pipenv run create-geoparquet`

-
-### Running tests
-
-You'll need to install [nodejs and npm](https://nodejs.org/en/download/) to run the tests.
-Alternatively, you can also use [yarn](https://yarnpkg.com/) instead of npm.
-In this case replace all occurrences of `npm` with `yarn` below.
-Additionally, you need Python >= 3.9 installed.
-
-Afterwards, navigate to the root of the specification repository.
-Now, install the required test software: `npm install` and `npm run init`
-
-Finally, you can run all tests or subset of them:
-
-- To run all tests: `npm test`
-- To check the markdown run: `npm run check-docs`
-- To check the examples run: `npm run check-examples`
+See the [contributing guideline](CONTRIBUTING.md) for more details.
