+Install from PyPI
+=================
+
+For most Python users, the quickest way to get started is to install the Apache
+TVM wheel from PyPI:
+
+.. code-block:: bash
+
+   pip install apache-tvm
+
+This installs the Python package, including modules such as ``tvm.tirx``, and
+is suitable for trying tutorials that do not require a custom build.
+
+For more details on installing the TIRx compiler and optional kernel library,
+visit the :doc:`TIRx installation </tirx/install>` page. If you need to
+customize TVM's build configuration, visit the
+:ref:`install TVM from source <install-from-source>` page instead.
