+# Development Environment
+
+These VSCode devcontainers setup multiple environments for testing against
+different python versins.
+
+## Setup
+
+```
+$ git clone [email protected]:splintered-reality/py_trees.git
+$ code ./py_trees
+```
+
+## VSCode DevContainer
+
+At this point you can either "Re-open project in container" to develop against
+the default python version.
+
+Alternatively "Open Folder in Container" and point it at one of the
+`py<MAJOR><MINOR>` subfolders in this directory to develop against a different
+python version.
