+### Note about setup paths
+
+This project contains both Javascript and Python, for the client and server respectively. Make sure you are in the
+correct directory when working with each part.
+
+Most of these setup commands should be run in the Python environment and the `api/` directory:
+
+```shell
+> cd api
+> pwd
+/home/ssube/code/github/ssube/onnx-web/api
+```
+
+The Python virtual environment will be created within the `api/` directory.
+
+The Javascript client can be built and run within the `gui/` directory.

+There is [a `requirements.txt` file](./api/requirements.txt) in the `api/` directory, so you can install all of these

+At the moment, none of these packages seem to need specific versions. There is a warning about an incompatibility in
+Protobuf, and some of the gist guides recommend `diffusers=0.3.0`, but I had trouble with old versions of `diffusers`
+before 0.6.0 or so. If I can determine a good set of working versions, I will pin them in `requirements.txt`.
