+Nox as Task Executor and Task Creation
+--------------------------------------
+
+Why Nox Was Chosen
+~~~~~~~~~~~~~~~~~~
+
+Nox was initially selected as our task executor due to several reasons:
+
+* **No Additional Languages Required**: There was no need to introduce extra programming languages or binaries, simplifying the development process.
+* **Python-based**: Being Python-based, Nox can be extended, understood by python devs and also can share code.
+* **Simplicity**: Nox is relatively "small" in functionality which makes it somewhat simple to use.
+
+Although today, other options like `invoke` could be consider or used as a replacement, Nox still is working for use even though there are some rough edges.
+
+Naming of Tasks and Grouping
+----------------------------
+
+Task Grouping with Nox
+~~~~~~~~~~~~~~~~~~~~~~
+
+Since Nox doesn't natively support task grouping like Invoke, we need a strategy to clearly distinguish commands. We will adopt a naming convention to indicate grouping within the CLI. 
+
+Groups will be separated using a :code:`:` (colon) because :code:`-` (dash) might already be used within task names.
+
+Examples
+++++++++
+
+**Task Names:**
+
+* :code:`docs:clean`
+* :code:`docs:build`
+* :code:`docs:open`
+
+
+**CLI Execution:** :code:`nox -s docs:clean docs:build docs:open`
+
+This approach helps in organizing tasks logically and makes it easier for developers to identify and execute related commands.
+
+By following these guidelines, we ensure a structured and comprehensible task management system, facilitating smoother development and maintenance.
