+## Using a proxy
+
+Your organization may require to use a proxy server to reach to the public internet.
+Use the `--proxy` option, and if you need to pass a specific private CA certificate you may
+use the REQUESTS_CA_BUNDLE environment variable.
+
+Example on a Unix based OS:
+```
+$ REQUESTS_CA_BUNDLE=~/ssl-proxying-certificate.pem akamai etp --proxy 127.0.0.1:8888 list get
+```
