+The following assumes the `python27` software collection, but other version of Python are supported
+too.  The initial setup and deployment of Software Collections is beyond the scope of this doc.

+#### Use pip without installing it
+
+If you have a copy of the `pip*.whl` (wheel) file, then it can be executed directly by python.  This
+can be used to run `pip` without actually installing it, or for install pip initially (bypassing the
+`get-pip.py` script step noted above.)
+
+Here's an example of how this could work:
+
+**Step 1:** Download the pip wheel on a machine where `pip` works, by running:
+
+    pip download pip -d .
+
+This will create a file like `pip-19.0.1-py2.py3-none-any.whl` in the current working directory.
+
+**Step 2:** Copy the pip wheel to another machine (likely where pip isn't installed.)
+
+**Step 3:** Execute the wheel by running:
+
+    python pip-19.0.1-py2.py3-none-any.whl/pip list
+
+Just substitute the `list` command with whatever action you need (like `install` or whatever)
