+We are in the process of switching nullability annotation libraries, so you might need to use one or the other:
+
+**For classes we add**: Fields, method parameters and return types that are nullable should be marked via the
+`@Nullable` annotation from `org.jspecify.annotations`. Whenever you create a new class, add `@NullMarked`, meaning types
+are assumed to be non-null by default. For less obvious placing such as on generics or arrays, see the [JSpecify docs](https://jspecify.dev/docs/user-guide/).
+
+**For classes added by upstream**: Keep using both `@Nullable` and `@NotNull` from `org.jetbrains.annotations`. These
+will be replaced later.

+## Reporting a Vulnerability
+
+For any issues that are NOT duplication bugs, server/client crashes, or otherwise serious exploits, please open an issue
