+## How to record tests cassettes
+
+### Run the server
+
+Checkout [opentelemetry-go](https://github.com/open-telemetry/opentelemetry-go) and build it with:
+
+```
+make
+```
+
+Then run the example server with:
+
+```
+./internal/examples/server/bin/server
+```
+
+### Record the cassettes
+
+We are using `vcr.py` for recording HTTP responses from the server, it works by serializing the response in a yaml file and then replying
+it. `vcr.py` will record a new cassettes only if it does not find it so to redo a recording you need to delete the recording in the
+`cassettes/` directory.
+
+Because of vcr.py issues with older urllib3 versions tests are skipped with Python older than 3.10.
