+VS Code [devcontainer](https://code.visualstudio.com/docs/devcontainers/containers) feature allows your coding environment to be hosted inside a docker container, providing all the tools and consistent environment of that docker container, without needing to install everything onto your computer manually.
+
+This can be set up quickly by adding a `.devcontainer.json` file to the root folder of your project, after which VS Code will ask in a popup if you want to re-open your project in the container.
+Here's an example `.devcontainer.json` micropython project file you could base yours on:
+``` json

+  "name": "Micropython Project",
+  "image": "micropython/unix:latest",

+The image used could be swapped from `micropython/unix:latest` to `espressif/idf:release-v4.4` if you want to compile for esp32, or one with arm-none-eabi-gcc like `registry.gitlab.com/alelec/docker-arm-none-eabi:latest` for building arm ports like stm32 or mimxrt.
