+Build, test and benchmark
+=========================
+
+``xtensor-python`` build supports the following options:
+
+- ``BUILD_TESTS``: enables the ``xtest`` and ``xbenchmark`` targets (see below).
+- ``DOWNLOAD_GTEST``: downloads ``gtest`` and builds it locally instead of using a binary installation.
+- ``GTEST_SRC_DIR``: indicates where to find the ``gtest`` sources instead of downloading them.
+
+All these options are disabled by default. Enabling ``DOWNLOAD_GTEST`` or
+setting ``GTEST_SRC_DIR`` enables ``BUILD_TESTS``.
+
+If the ``BUILD_TESTS`` option is enabled, the following targets are available:
+
+- xtest: builds an run the test suite.
+- xbenchmark: builds and runs the benchmarks.
+
+For instance, building the test suite of ``xtensor-python`` and downloading ``gtest`` automatically:
+
+.. code::
+
+    mkdir build
+    cd build
+    cmake -DDOWNLOAD_GTEST=ON ../
+    make xtest
+
+To run the benchmark:
+
+.. code::
+
+    make xbenchmark
+
+To test the Python bindings:
+
+.. code::
+
+    cd ..
+    pytest -s
