+# CI Signaling
+
+Its possible to configure CI on build a project based on flags in the commit message. This is done by adding a special line to the commit that starts with CI: (must be all caps). The line can contain a list of flags separated by semi-colons. The following flags are supported:
+- skip=<Name of stage>
+- skip_branch=<Name of parallel branch to skip>:<Name of parent stage>
+- enable_only_branch=<Name of parallel branch to enable>:<Name of parent stage>
+- env:<Name of environment variable>=<Value of environment variable>

+# Doc Creation
+
+Doc is create by leveraging Sphinx as the documentation engine. To create the entire documentation set you must generate the dynamic pages which document the system object APIs and the reference designs. Then the output targets can be run. Since doc gen requires sphinx and some plugins they need to be installed first and ideally in a virtual environment. The following commands will create a virtual environment and install the necessary packages:
+
+```bash
+python3 -m venv venv
+source venv/bin/activate
+pip install -r CI/doc/requirements_doc.txt
+```
+
+Next we can build the documentation. The following commands will build the documentation and place it in the *build* folder under the *CI/doc* folder:
+
+```bash
+make -C CI/doc gen_autodocs html
+```
+
+## Updating the System Object Documentation
+
+The system object documentation is generated from the MATLAB code and comments, which requires use of MATLAB itself. By running the script gen_sysobj_doc.m within the *gen_pages* folder, it will create the necessary sysobjs.json file which sphinx will then use to create the individual component pages. This is done by running the following command from the root of the toolbox in MATLAB:
+
+```matlab
+cd CI/doc/gen_pages
+gen_sysobj_doc
+```
