+Integration repositories
+========================
+
+.. important::
+   The Integration project deals with lots of code repositories.
+
+
+Most of the repositories are internal ONAP repositories.

+several sub-repositories.
+
+Integration
+-----------
+
+The integration repository is the historical repository.
+As a consequence it includes several elements in the same reppository:
+
+- Deployment scripts (deployment directory)
+- Tests: the first non robot tests (security, vCPE,..)
+- Simulators/emulators (test/mocks)
+- Integration and use cases documentation (docs)
+- Tools (bootstrap, S3Ptools)
+
+Since Frankfurt version, we created more smaller repositories especially for the use
+cases and the simulators.
+It shall help improving the maintenance of the different elements.
+It shall also help identifying, leveraging and adopting existing simulators
+rather than systematically re-inventing the wheel.
+
+.. attention::
+   The **new integration sub-repositories** introduced for Guilin are:
+
+  - 5G-core-nf-simulator
+  - terraform
+  - terragrunt

+
+Testsuite
+---------
+
+The testsuite repository and it sub repositories deal excelusively with tests.
+
+The testsuite repository includes all the robotframework scripts.
+The robot pod that can be installed as part of the ONAP cluster is build from
+this repository.
+
+Several tooling repositories are associated with the robot tests (heatbridge,
+robot-python-testing-utils).
+
+.. attention::
+   For Guilin, 3 new sub repositories have been created:
+
+   - testsuite/cds
+   - pythonsdk-test
+   - robot-utils
+
+.. csv-table:: Testsuite Repositories
+    :file: ./files/csv/repo-testsuite.csv
+    :widths: 30,50,20
+    :delim: ;
+    :header-rows: 1
+
+Demo
+----
+
+In this repository you will find any artifacts needed for demo, PoC and use cases
+if they do not have their own repository (mainly old use cases).
+
+.. csv-table:: Demo Repository
+    :file: ./files/csv/repo-demo.csv
+    :widths: 30,50,20
+    :delim: ;
+    :header-rows: 1
+
+Oparent
+-------
+
+.. csv-table:: Oparent Repository
+    :file: ./files/csv/repo-oparent.csv
+    :widths: 30,50,20
+    :delim: ;
+    :header-rows: 1
+
+
+External repositories
+---------------------
+
+Additionnaly, the Integration team also deals with external gitlab.com
+repositories.
+
+.. csv-table:: Integration external repositories table
+    :file: ./files/csv/repo-integration-external.csv
+    :widths: 30,50,20
+    :delim: ;
+    :header-rows: 1
+
+The python-onapsdk has been developped out of ONAP as gitlab provided more
+enhanced built-in features for this kind of developments.
+
+The xtesting-onap repository is also hosted in gitlab.com as the CD part of
+Integration work is based on public gitlab-ci chains.
