+Running Blueprints Processor Microservice in an IDE
+====================================================
+
+Objective
+~~~~~~~~~~~~
+
+Have the processor running locally is to use the IDE to run the code, while having the database running in a container. 
+This way, code changes can be conveniently tested and debugged.
+
+
+Check out the code
+~~~~~~~~~~~~~~~~~~~
+
+Check out the code from Gerrit: https://gerrit.onap.org/r/#/admin/projects/ccsdk/cds
+
+Build it locally
+~~~~~~~~~~~~~~~~~~
+
+In the checked out directory, type
+
+.. code-block:: bash
+
+   mvn clean install -DskipTests=true -Dmaven.test.skip=true -Dmaven.javadoc.skip=true -Dadditionalparam=-Xdoclint:none
+
+Spin up a Docker container with the database
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Blueprints Processor project uses a database to store information about the blueprints 
+and therefore it needs to be online before attempting to run it.
+
+One way to create the database is by using the :file:`docker-compose.yaml` 
+file present on the distribution module. This database will require a local directory to mount a volume, before running docker-compose remember to create following directory:
+
+.. code-block:: bash
+
+   mkdir -p -m 755 /opt/app/cds/mysql/data
+
+Navigate to the docker-compose file in the distribution module:
+
+.. tabs::
+
+   .. group-tab:: Latest
+
+      .. code-block:: bash
+
+         cd ms/blueprintsprocessor/application/src/main/dc
+
+   .. group-tab:: Frankfurt
+
+      .. code-block:: bash
+
+         cd ms/blueprintsprocessor/application/src/main/dc
+
+   .. group-tab:: El Alto
+
+      .. code-block:: bash
+
+         ms/blueprintsprocessor/distribution/src/main/dc
+
+   .. group-tab:: Dublin
+
+      .. code-block:: bash
+
+         ms/blueprintsprocessor/distribution/src/main/dc
+
+And run docker-composer:
+
+.. code-block:: bash
+
+    docker-compose up -d db
+
+This should spin up a container of the MariaDB image in the background.
+To check if it has worked, this command can be used:
+
+.. code-block:: bash
+
+    docker-compose logs -f
+
+The phrase ``mysqld: ready for connections`` indicates that the database was started correctly.
+
+From now on, the Docker container will be available on the computer; if it ever gets stopped,
+it can be started again by the command:
+
+.. code-block:: bash
+
+   docker start <id of mariadb container>
+
+
+Set permissions on the local file system
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Blueprints processor uses the local file system for some operations and, therefore,
+need some existing and accessible paths to run properly.
+
+Execute the following commands to create the needed directories, and grant access to the current user to modify them:
+
+.. code-block:: bash
+
+   mkdir -p -m 755 /opt/app/onap/blueprints/archive
+   mkdir -p -m 755 /opt/app/onap/blueprints/deploy
+   mkdir -p -m 755 /opt/app/onap/scripts
+   sudo chown -R $(id -u):$(id -g) /opt/app/onap/
+
+Import the project on the IDE
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For this page, the chosen IDE is IntelliJ, but the instructions present here can
+be adapted to be used in other IDEs as well.
+
+Go to *File | Open* and choose the :file:`pom.xml` file of the cds directory:
+
+|imageImportProject|
+
+Sometimes it may be necessary to reimport Maven project:
+
+|imageReimportMaven|
+
+
+Override some application properties
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After the project is compiled, a Run Configuration profile overriding some application properties
+with custom values needs to be created, to reflect the local environment characteristics.
+
+.. tabs::
+
+   .. group-tab:: Latest
+
+      Navigate to the main class of the Blueprints Processor, the BlueprintProcessorApplication class:
+
+      ``ms/blueprintsprocessor/application/src/main/kotlin/org/onap/ccsdk/cds/blueprintsprocessor/BlueprintProcessorApplication.kt``.
+
+      Right-click inside it, at any point, to load the context menu and select create 
+      BlueprintProcessorApplication configuration from context:

+      |imageRunConfigKt|

+
+      .. code-block:: bash
+         :caption: **Custom values for properties**
+
+         -Dspring.profiles.active=dev
+
+      You can override any value from **application-dev.properties** file here. Use the following pattern:
+
+      .. code-block:: java
+
+         -D<application-dev.properties key>=<application-dev.properties value>

+Add/replace the following in Blueprint's application-dev.properties file:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: java
+
+   blueprintsprocessor.grpcclient.remote-python.type=token-auth
+   blueprintsprocessor.grpcclient.remote-python.host=localhost
+   blueprintsprocessor.grpcclient.remote-python.port=50051
+   blueprintsprocessor.grpcclient.remote-python.token=Basic Y2NzZGthcHBzOmNjc2RrYXBwcw==
+
+   blueprintprocessor.remoteScriptCommand.enabled=true
+
+
+Run the application
+~~~~~~~~~~~~~~~~~~~
+
+Select either run or debug for this Run Configuration to start the Blueprints Processor:
+
+|imageRunDebug|
+
+|imageBuildLogs|
+
+
+Testing the application
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are two main features of the Blueprints Processor that can be of interest of a developer:
+blueprint upload and blueprint process.
+
+To upload custom blueprints,  the endpoint ``api/v1/execution-service/upload`` is used.
+
+To process, the endpoint is ``api/v1/execution-service/process``.
+
+Postman is a software that can be used to send these request, and an example of
+them is present on https://www.getpostman.com/collections/b99863b0cde7565a32fc.
+
+
+Possible Fixes
+~~~~~~~~~~~~~~~~~~~
+
+Imported packages or annotiations are not found, Run Config not available?
+*****************************************************************************
+
+1. Rebuild with ``maven install ...`` (see above)
+2. Potentially change Maven home directory in Settings
+3. Maven reimport in IDE
+
+Compilation error?
+********************
+
+* Change Java Version to 11 or 8
