+
+Core of UniGrammar runtime contains a common framework with minimal dependencies that can be used when creating or wrapping parser generators without actually using `UniGrammar`. It is needed because if you are using OOP, you still have to have some interface, and it would be better if that interface is compatible to the one used in `UniGrammar`, so we won't have to rewrap stuff again and again. There are no stability guarantees though. You are expected to be able to do necessary changes in your code if you use it.
+
+It is splitted into a separate package because we don't want to require its users to install `UniGrammarRuntime` and its dependencies.
+
+It doesn't use `UniGrammar` package as a namespace because this stuff is incompatible to `pip install -e .` (components installed as `-e` break every other components, an it is probably a bug in python), so it has to have an own name `UniGrammarRuntimeCore`.
