+# RMM Development Containers
+
+This directory contains [devcontainer configurations](https://containers.dev/implementors/json_reference/) for using VSCode to [develop in a container](https://code.visualstudio.com/docs/devcontainers/containers) via the `Remote Containers` [extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) or [GitHub Codespaces](https://github.com/codespaces).
+
+This container is a turnkey development environment for building and testing the RMM C++ and Python libraries.
+
+## Table of Contents
+
+* [Prerequisites](#prerequisites)
+* [Host bind mounts](#host-bind-mounts)
+* [Launch a Dev Container](#launch-a-dev-container)
+
+## Prerequisites
+
+* [VSCode](https://code.visualstudio.com/download)
+* [VSCode Remote Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
+
+## Host bind mounts
+
+By default, the following directories are bind-mounted into the devcontainer:
+
+* `${repo}:/home/coder/rmm`
+* `${repo}/../.aws:/home/coder/.aws`
+* `${repo}/../.local:/home/coder/.local`
+* `${repo}/../.cache:/home/coder/.cache`
+* `${repo}/../.conda:/home/coder/.conda`
+* `${repo}/../.config:/home/coder/.config`
+
+This ensures caches, configurations, dependencies, and your commits are persisted on the host across container runs.
+
+## Launch a Dev Container
+
+To launch a devcontainer from VSCode, open the RMM repo and select the "Reopen in Container" button in the bottom right:<br/><img src="https://user-images.githubusercontent.com/178183/221771999-97ab29d5-e718-4e5f-b32f-2cdd51bba25c.png"/>
+
+Alternatively, open the VSCode command palette (typically `cmd/ctrl + shift + P`) and run the "Rebuild and Reopen in Container" command.
