+# Dev Containers Quick Start
+
+The default location for usage snippets is the `samples` directory.
+
+## Running a Usage Sample
+
+A sample usage example has been provided in a `root.py` file. As you work with the SDK, it's expected that you will modify these samples to fit your needs. To execute this particular snippet, use the command below.
+
+```
+python root.py
+```
+
+## Generating Additional Usage Samples
+
+The speakeasy CLI allows you to generate more usage snippets. Here's how:
+
+- To generate a sample for a specific operation by providing an operation ID, use:
+
+```
+speakeasy generate usage -s .speakeasy/out.openapi.yaml -l python -i {INPUT_OPERATION_ID} -o ./samples
+```
+
+- To generate samples for an entire namespace (like a tag or group name), use:
+
+```
+speakeasy generate usage -s .speakeasy/out.openapi.yaml -l python -n {INPUT_TAG_NAME} -o ./samples
+```
