+# Reproducible development environments with VSCode devcontainers
+
+If `devcontainer` is set to `"y"` project uses the VSCode [devcontainer](https://code.visualstudio.com/docs/devcontainers/containers)
+specification to create a reproducible development environment. The devcontainer
+is defined in the `.devcontainer` directory and pre-installs all dependencies
+from poetry required to develop, test and build the project.
+
+The devcontainer also installs the pre-commit hooks and configures the VSCode python
+extension to use the appropriate python interpretor and pytest paths.
