 The `prometheus_multiproc_dir` environment variable must be set to a directory
 that the client library can use for metrics. This directory must be wiped
 between Gunicorn runs (before startup is recommended).
 
-Put the following in the config file:
-```python
-from prometheus_client import multiprocess
+This environment variable should be set from a start-up shell script,

 ## Parser
 
 The Python client supports parsing the Prometheus text format.
