 * Because this is an community repository, we need the approval from two maintainers to accept your new additions. See [discussion](https://github.com/iptv-org/iptv/discussions/8412) for further explanations.
 * If your television station broadcasts from other television stations, please read the *[Can I safely add an FTA channel that broadcasts PPV events or pay programming?](#Can-i-safely-add-an-fta-channel-that-broadcasts-ppv-events-or-pay-programming)* section.
 * The same id can only be used if a mirror stream is also proposed. Please do not set the same id for two different channels. See [PR](https://github.com/iptv-org/iptv/pull/9572).
+* If for some reason you need to edit the name of your channel, the id from the Database will be changed. We suggest that you update the new id from the playlist as soon as possible because the streams of your channel with modified name will not be automatically linked. See [PR](https://github.com/iptv-org/iptv/pull/9632).
