+# .devcontainer
+
+A [development container][container] provides a predefined environment with
+some tools needed for development, which can be useful in editors such as
+[Visual Studio Code][vscode] or remote settings like [Codespaces][codespaces].
+
+This specific container packages [the Slack CLI][cli] with the project runtime
+and a few development tools. The `Dockerfile` details the container.
+
+## Editor extensions
+
+Modifications to an editor can be made with changes to the `devcontainer.json`
