+# Run Continuous Integration (CI) Tests on Modal
+
+Note!
+The HF secret in Modal is named "huggingface-secret". Pls rename if your secret has another name.
+
+## Test modal deployment
+You can test pricer.ci in Modal:
+(`modal deploy -m pricer.ci`)
+In python CLI:
+(`import modal`)
+(`Pricer = modal.Cls.lookup("pricer-ci-testing", "Pricer")`)
+(`pricer = Pricer()`)
+(`reply = pricer.price.remote("Quadcast HyperX condenser mic, connects via usb-c to your computer for crystal clear audio")`)
+(`print(reply)`)
+
+## Unit testing
+Unit test strategy created like in 
+[This example repo](https://github.com/modal-labs/ci-on-modal)
+
+## Usage
+
+All commands below are run from the root of the repository (this directory).
+
+### Run tests remotely on Modal
+
+```bash
+modal run pricer.ci
+```
+
+On the first execution, the [container image](https://modal.com/docs/guide/custom-container)
+for your application will be built.
+
+This image will be cached on Modal and only rebuilt if one of its dependencies,
+like the `requirements.txt` file, changes.
+
+### Debug tests running remotely
+
+To debug the tests, you can open a shell
+in the exact same environment that the tests are run in:
+
+```bash
+modal shell pricer.ci
+```
+
+_Note_: On the Modal worker, the `pytest` command is run from the home directory, `/root`,
+which contains the `tests` folder, but the `modal shell` command will
+drop you at the top of the filesystem, `/`.
