-## :one: Request access
-
-The first step to add packages to ConanCenter is requesting access. To enroll in ConanCenterIndex repository, please write a comment
-requesting access in this GitHub [issue #4](https://github.com/conan-io/conan-center-index/issues/4). Feel free to introduce yourself and
-your motivation to join ConanCenter community.
-
-This process helps ConanCenter against spam and malicious code. The process is not fully automated on purpose and the requests are
-generally approved on a weekly basis. Feel free to continue to step :two: while waiting for approval.
-
-> **Note** The requests are reviewed manually, checking the GitHub profile activity of the requester to avoid any misuse of the service.
-> All interactions are subject to the expectations of the [code of conduct](../code_of_conduct.md). Any misuse or inappropriate behavior
-> are subject to the same principals.
+## :one: First time contributors
 
 When submitting a pull request for the first time, you will be prompted to sign the [CLA](https://cla-assistant.io/conan-io/conan-center-index) for your
 code contributions. You can view your signed CLA's by going to <https://cla-assistant.io/> and signing in.
 
-## Inactivity and user removal
-
-For security reasons related to the CI, when a user no longer contributes for a long period, it will be considered inactive and removed from the authorized user's list.
-For now, it's configured for **4 months**, and it's computed based on the latest commit, not comments or opened issues.
-After that time, the CI bot will ask to remove the user name from the authorized users' list through the access request PR, which occurs a few times every week.
-
-When you are interested in contributing again, simply ask again to be included in the [issue #4](https://github.com/conan-io/conan-center-index/issues/4).
-The process will be precisely like for newcomers.
