+## Asking about new patches
+These days, I do not create the patches. Everything is community submitted.
+If you would like new hex edits, make them yourself and make a pull request!
+
+## Submitting a new game
+Here is your checklist:
+- Add the new game html, it is easiest to copy an existing game and modify it.
+  The html should be named `[game][release].html` except IIDX because they just
+  happen to be `[release].html` only...
+- Modify the `<title>` tag and the `<h1>` tag to the name of the new game.
+- Modify the patcher for the new DLL names/patches.
+- Keep consistent indentation for the new patches. I will have to fix your PR if
+  it contains poor formatting, which will delay the merging process.
+- Modify `index.html` to add the new game. Sorting: alphabetical by game series,
+  then in release order per game.
+- Add a game image. 128x128px PNG files, please. Any blank space should be
+  either white or transparent.
+
+If your pull request is a single commit, I will rebase and merge. If it is
+multiple commits, I will squash and merge.
+
+Please do not worry about submitting "bad" PRs. If there is something wrong, I
+will tell you how to fix it or I will fix it myself before merging.
+
+Submitting a PR for an n-0 game is frowned upon in the general community and
+might make you disliked. The BemaniPatcher repository does not judge, and **I
+will merge n-0 patches**, but please be mindful that your submission may have
+unintended consequences for you.
