 This document describes how to configure and use your development environment.
 
-!!! note
-
-    All terminal commands listed below are assumed to be run from the root of the repository.
+## Prerequisites
 
-## Initial setup
+You must complete these steps once before you can start setting up the project itself:
 
 1. Install [Python 3.10](https://www.python.org/downloads/).
-2. Install [poetry](https://python-poetry.org/docs/master/#installation).
-3. Install dependencies of this project by running this command:
+2. Verify that `python` can be launched by running this command in a **new** terminal:
     ```shell
-    poetry install
+    python --version
     ```
+    If this fails, add the directory that contains the `python` executable to your `PATH` environment variable.
 
-## Running the tests
-
-1. Run this command:
+3. Install [Poetry](https://python-poetry.org/docs/master/#installing-with-the-official-installer) with the official installer. Follow the instructions for your operating system in the linked document.
+4. Verify that `poetry` can be launched by running this command in a **new** terminal:
     ```shell
-    poetry run pytest
+    poetry --version
     ```
+    If this fails, add the directory that contains the `poetry` executable to your `PATH` environment variable.
+
+## Project setup
+
+Follow the instructions for your preferred IDE. If you want to use neither [PyCharm](https://www.jetbrains.com/pycharm/) nor [Visual Studio Code](https://code.visualstudio.com/), use the generic instructions. You only need to do these steps once.
+
+!!! note
+
+    All terminal commands listed in this section are assumed to be run from the root of the repository.
+
+=== "PyCharm"
+
+    1. Clone the repository.
+    2. Open the project folder in PyCharm.
+    3. Follow the instructions in the [PyCharm documentation](https://www.jetbrains.com/help/pycharm/poetry.html#poetry-env) to create a **new** Poetry environment and to install the dependencies of the project.
+    4. Open the PyCharm settings and search for "Python Integrated Tools". Set the "Default test runner" to "pytest" and the "Docstring format" to "NumPy". Your settings should look like this:
+        ![PyCharm settings "Python Integrated Tools"](./img/pycharm_python_integrated_tools.png)
+
+=== "Visual Studio Code"
+
+    1. Clone the repository.
+    2. Open the project folder in Visual Studio Code.
+    3. Install the [Python extension](https://marketplace.visualstudio.com/items?itemName=ms-python.python).
+    4. Create a new Poetry environment and install the dependencies of the project by running this command:
+        ```shell
+        poetry install
+        ```
+    5. Find the path to the Poetry environment that was created in step 4 by running this command:
+        ```shell
+        poetry env info --path
+        ```
+    6. Copy the output of step 5 to your clipboard.
+    7. Open the command palette and search for "Python: Select Interpreter".
+    8. Select the Poetry environment that matches the output of step 5. It should show up in the list of available interpreters. If it does not, you can pick it manually by choosing "Enter interpreter path..." and pasting the path that you copied in step 6 into the input field.
+    9. Open the command palette and search for "Python: Configure Tests".
+    10. Select "pytest" as the test runner.
+    11. Select "tests" as the directory containing tests.
