-# A Hacktoberfest update
-
-Welcome Hacktoberfest participants!  We commit to actively seek, help, and merge your
-improvements to lakeFS.  We've labelled some [issues with the hacktoberfest
-label](https://github.com/treeverse/lakeFS/issues?q=is%3Aissue+is%3Aopen+label%3Ahacktoberfest).
-Please check out our [contributing guide](https://docs.lakefs.io/contributing).
-
-*We know you like badges, stickers, and T-shirts*, and **we like them too!** But, like many
-other open-source projects, we are seeing an influx of lower quality PRs.  During October will
-be unable to accept PRs if they:
-
-1. Only change punctuation or grammar, unless accompanied by an explanation or are clearly
-   better.
-1. Repeat an existing PR, or try to merge branches authored by other contributors that are under
-   active work.
-1. Do not affect generated code or documentation in any way.
-1. Are detrimental: do not compile or cause harm when run.
-1. Change text or code that should be changed upstream, such as licenses, code of conduct, or
-   React boilerplate.
-
-You can **help us accept your PR** by adding a clear title and description to the PR and to
-commits in that PR.  "Fixes #1234" or "update README.md" are not as good as "Make lakeFS run 3x
-faster" or "Add update regarding Hacktoberfest".
-
-Thanks!
