 ## Instructions:
 
-- Custom functions can be added under `app/custom_functions/examples.py`. There is a sample custom function included that can be run via `=XLWINGS.HELLO("xlwings")`. There's also a streaming function (`=XLWINGS.STREAMING_RANDOM(2, 3)`). The `XLWINGS` prefix ("namespace") can be adjusted in via the settings (`XLWINGS_FUNCTIONS_NAMESPACE` in `.env` file). Except for the prod environment, `-dev` and `-staging` are automatically appended to avoid name clashes.
-- Macros can be added under `app/routers/macros/example.py`. They will need to be bound to a button on either the ribbon (via `app/templates/manifest.xml`) or task pane (via `app/templates/taskpane.html`). There is a sample button `Hello World` included on both the ribbon and task pane.
+- Custom functions can be added under `app/custom_functions/examples.py`. To add your own Python modules, see the instructions at the top of `examples.py`.

The `XLWINGS` prefix ("namespace") can be adjusted in via the settings (`XLWINGS_FUNCTIONS_NAMESPACE` in `.env` file). Except for the prod environment, `-dev` and `-staging` are automatically appended to avoid name clashes. So if you run this under a dev environment, you'll find the custom functions under the `XLWINGS-DEV` prefix.
