+# Tika Chinese Image
+
+Apache Tika server with Simplified & Traditional Chinese OCR support (Tesseract) and common Chinese fonts, based on `apache/tika:3.3.0.0-full`.
+
+## Pull the image
+
+```bash
+docker pull ghcr.io/chenyme/tika:latest
+```
+
+## Start the server
+
+```bash
+docker run -d -p 9998:9998 ghcr.io/chenyme/tika:latest
+```
+
+The container uses `-c /tika-config.xml` by default, which enables Tesseract OCR with Simplified Chinese (`chi_sim`), Traditional Chinese (`chi_tra`), and English (`eng`).
+
+## Use the server
+
+```bash
+# Parse a file
+curl -T /path/to/document.pdf http://localhost:9998/tika
+
+# Check server status
+curl http://localhost:9998/tika
+```
