+# Sandbox Usage
+
+Without any other setup, play with the tools you want temporarily:
+
+`sh <(curl https://tea.xyz) +python.org +pip.pypa.io sh`
+
+
+# ... or With tea Installed
+
+Same as above, but with 'tea' instead of the "sh <(...)", thus:
+
+`tea +python.org +pip.pypa.io sh`
+
+
+# ... or With a [Developer Environment](https://docs.tea.xyz/features/developer-environments):
+
+Add the tool dependencies to your dev docs and enter a shell where it's all available:
+
+`tea -E sh`
+
+
+
+# ... and With [Magic](https://docs.tea.xyz/features/magic)
+
+`cd my-sandboxed-project`
+
+... and everything is just _there_.
