+## Eigen CI infrastructure
+
+Eigen's CI infrastructure uses two stages: A `build` stage to build the unit-test
+suite and a `test` stage to run the unit-tests.
+
+### Build Stage
+
+The build stage consists of the following jobs:
+
+| Job Name                                 | Arch      | OS             | Compiler   | C++11   |

+| `build:aarch64:linux:clang-10:cxx11-on`  | `AArch64` | `Ubuntu 18.04` | `Clang-10` | `On`    |
+
+### Test stage
+
+In principle every build-job has a corresponding test-job, however testing supported and unsupported modules is divided into separate jobs. The test jobs in detail:
