-1) Pull requests for the MAIN branch will be closed.
-2) DO NOT include translations in your PR. Only English US sentences.
+- Please do not submit solutions for problems that are not already reported in an issue.
+- Unfortunately, Firefly III can't be your learning experience. If you're new to all of this, please open an issue first.
+- Please do not open PRs to "discuss" possible solutions or to "get feedback" on your code. I simply don't have time for that.
+- Pull requests for the MAIN branch will be closed.
+- DO NOT include translated strings in your PR.
+- PRs (or parts thereof) that only fix issues inside code comments will not be accepted.
