+# burr has moved to apache-burr
+
+This package is a redirect. Burr is now developed under the Apache
+Software Foundation as **Apache Burr (incubating)**.
+
+## Migration
+
+Replace `burr` with `apache-burr` in your dependencies:
+
+```bash
+pip install apache-burr
+```
+
+Extras carry over identically (`apache-burr[start]`, `apache-burr[tracking-server]`,
+etc.). The Python import path is unchanged — `from burr.core import ...`
+keeps working — because installing `apache-burr` installs the same `burr`
+Python module.
+
+For documentation and getting started, see:
+- https://burr.apache.org/
+- https://github.com/apache/burr
+
+This `burr` package on PyPI exists to keep `pip install burr` working for
+users on muscle memory or pinned dependencies. It contains no source code;
+it simply pins `apache-burr` of the matching version.
