 Bazel promises reproducable builds which I liked. I tried it on a virtual (via UTM) debian 13 (trixie) arm64 machine. The openroad binary is a gui application which relies on qt. It seems quite difficult to have system independent gui application. OpenROAD uses prebuild libraries, for example the xcd libraries which are from [[https://github.com/The-OpenROAD-Project/qt_bazel_prebuilts/tree/main/interface_libs|OpenROADS qt_bazel_prebuilts/interface_libs]]. It turns out that prebuild libraries are build in a ubuntu docker container and the copied to the repository. Therefore they are x86_64 and do not work on the arm64 machine.
-I gave up on that one for the time being.
+== Install bazelisk ==
+See: https://github.com/bazelbuild/bazelisk/releases/tag/v1.28.1
+for the different systems. For debian linux on x86_64 machines do:
+<code>
+wget https://github.com/bazelbuild/bazelisk/releases/download/v1.28.1/bazelisk-amd64.deb
+sudo dpkg -i bazelisk-amd64.deb
+</code>
+== Build and Run openroad in cmdline mode ==
+The will build and run the openroad tool in cmdline mode.
+<code>
+bazelisk run //:openroad
+</code>
+== Build and run in gui mode ==
+<code>
+bazelisk run --//platform=gui //:openroad -- -gui
+</code>
+== Run the regression test via bazel ==
+The following command will run all tests which are defined in the
+src folder. The three dots are real.
+<code>
+bazelisk test src/...
+</code>
+== Run one test from the regression ==
+<code>
+bazelisk test src/gpl/test:simple01-tcl_test
+</code>

+=== Regression Test ===
+To be sure that the compiled tools are actually working as expected on possibly different platforms, a regression test is a good idea. The [[https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/README.md|README.md]] mentions some tests. Run:
+<code>
+./test/regression flow
+ctest --test-dir build -j 8
