+## 📖 Interactive Explainers
+
+We publish interactive visual explainers for frequently asked questions. Each issue gets a dedicated page with animations, code references, and CN/EN bilingual support.
+
+🔗 **[Hub Page](https://evolvinglmms-lab.github.io/OneVision-Encoder/)**

+| Issue | Topic | Page |

+| [#105](https://github.com/EvolvingLMMs-Lab/OneVision-Encoder/issues/105) | How OCR annotations are used during training | [issue-105.html](https://evolvinglmms-lab.github.io/OneVision-Encoder/issues/issue-105.html) |
+
+This table will be updated as more explainers are added. If you have a question that would benefit from a visual explanation, feel free to [open an issue](https://github.com/EvolvingLMMs-Lab/OneVision-Encoder/issues/new).
