+### Yarn Deduplication Issue
+
+This section highlights a known issue with Yarn leading to multiple versions of `video.js` being
+installed in a project, contrary to npm's deduplication to a single version.
+
+#### Issue Details
+
+- **Scenario**: Cyclic dependencies involving `video.js` result in conflicting versions being
+  installed via Yarn.
+- **Symptoms**: This causes compatibility issues, such as the `eme` plugin loading in only
+  one `video.js` instance, leading to errors.
+
+#### Workaround
+
+To mitigate this issue, force Yarn to resolve `video.js` to a single version (`8.11.8`) by adding
+the following to your project's `package.json`:
+
+```json
+"resolutions": {
+  "video.js": "8.11.8"
+}
+```
+
