 Please also make sure to add an extra `params` section with `params.config_profile_description`, `params.config_profile_contact` and `params.config_profile_url` set to reasonable values.
 Users will get information on who wrote the configuration profile then when executing a nf-core pipeline and can report back if there are things missing for example.
 
-### Checking user hostnames
-
-If your cluster has a set of consistent hostnames, nf-core pipelines can check that users are using your profile.
-Add one or more hostname substrings to `params.hostnames` under a key that matches the profile name.
-If the user's hostname contains this string at the start of a run or when a run fails and their profile does not contain the profile name, a warning message will be printed.
-
 ### Testing
 
 If you want to add a new custom config file to `nf-core/configs` please test that your pipeline of choice runs as expected by using the [`-c`](https://www.nextflow.io/docs/latest/config.html) parameter.
