# Official IOCCC rules These rules are **OFFICIAL**. Unless some significant problem turns up (such as a need to delay in when the IOCCC will close, or some major bug is discovered) they will remain **OFFICIAL** for this IOCCC. See our FAQ on "[rules, guidelines, tools feedback](../faq.html#feedback)" as well as our FAQ on "[about asking questions](../faq.html#question)" about these rules. You might also find the FAQ in general useful, especially the FAQ on "[how to enter the IOCCC](../quick-start.html#enter)". **SUGGESTION**: Watch both the [IOCCC news](../news.html) and the [IOCCC Mastodon](https://fosstodon.org/@ioccc) feed for the latest news about any _mentions_ changes. **HINT to mastodon users**: You may wish to refresh the [@IOCCC mastodon feed](https://fosstodon.org/@ioccc) page and/or mastodon app from time to time to view IOCCC mastodon updates. # The IOCCC open for submissions See "[FAQ - How may I enter the IOCCC](../quick-start.html#enter)" for information on how to register for the IOCCC, how to create a proper bzip2 compressed tarball of your submission, and how to upload your bzip2 compressed tarball to the IOCCC submit server.
