+This directory outlines a template which specifies the implementation of all vdk-core
+plugins. It includes a setup.py file, a /src/ directory containing all the plugin hooks
+and additional implementation files, a /tests/ directory containing all plugin-specific
+tests, and a .plugin-ci.yml file which specifies the CI/CD relevant to the plugins.
+
+The CI/CD is separated in two stages, a build stage and a release stage.
+The build stage is made up of three jobs, all which inherit from the same
+job configuration and only differ in the Python version they use (3.7, 3.8, 3.9 and 3.10).
+They run according to three rules, which are ordered in a way such that changes to a
+plugin's directory or the main directory triggers them, but changes to a different plugin
+do not.
+
+In order to add a new plugin , copy the plugin-template directory and follow the instructions in the files Generally those are
+
+* Update the setup.py file with correct name of the plugin;
+* Update `.plugin-ci.yml` file with name of the plugin - make sure to follow comments;
+* Include your implementation files inside the `src` folder;
+* Include any tests inside the `tests` so they can be ran by CI framework automatically.
+
+In order to build and test a plugin go to the plugin directory and use `../build-plugin.sh` script to build it
