+- If the `--insecure` option is set to `false` and the `HTTPIE_VERIFY_SSL` environment variable is set, we keep its value instead of overwrite it to `yes`.
+  Useful when we want to use Custom <abbr title="Certificate Authority">CA</abbr> (e.g. `HTTPIE_VERIFY_SSL=/etc/ssl/certs/ca-certificates.crt`). For more information, you can read the [HTTPie docs](https://httpie.org/doc/1.0.3#custom-ca-bundle)
