+Development Process and CI/CD Pipeline
+======================================
+
+This document outlines the branching strategy, development workflow, and GitHub Actions CI/CD pipeline used in the project to maintain code quality and streamline deployment.
+
+Branching Strategy
+------------------
+
+The project follows a structured branching strategy to separate development, staging, and production environments:
+
+- **feature branches** Branch**: Each feature or fix is developed in its own branch, prefixed with "feature" (e.g., `feature_123`). This branch is where individual developers work until the feature is ready for testing.
+- **dev**: The main development branch where validated feature branches are merged. It serves as an integration branch for all features under development.
+- **alpha**: A pre-release or staging branch that reflects a stable version of `dev`. Once `dev` reaches a stable point, it is merged into `alpha` for final testing before production.
+- **master**: The production branch. Only stable and fully tested code is merged here, and this branch is automatically deployed to PyPI upon tagging.
+
+Pushes and Merge Workflow
+-------------------------
+
+1. **Feature Branch Development**:
+   - Each developer creates a `featureXXX` branch to work on their feature.
+   - When the feature is complete, a pull request (PR) is made to merge `featureXXX` into `dev`.
+   - GitHub Actions will automatically run tests and generate a coverage report on the PR.
+   - If the tests pass, the feature can be merged into `dev`; if tests fail, the PR cannot be merged until issues are resolved.
+
+2. **Development Integration on `dev`**:
+   - Multiple `featureXXX` branches may be merged into `dev` concurrently.
+   - This branch is intended for integrating and testing new features collectively before staging.
+   - When `dev` reaches a stable state with passing tests, it can proceed to the `alpha` branch.
+
+3. **Alpha Testing on `alpha`**:
+   - The `dev` branch is merged into `alpha` for pre-release validation.
+   - GitHub Actions re-runs tests and generates a coverage report to verify stability.
+   - If all tests pass, the version is tagged on `alpha`, marking it as ready for release.
+   - Build and installation tests are also performed to ensure the package can be installed correctly.
+
+4. **Production Release on `master`**:
+   - The fully tested and working code is merged into `master`.
+   - The version is tagged on `master` to mark it as a stable release.
+   - Once there is a tag, a release is created on GitHub, documenting the changes.
+   - The released version is automatically published to PyPI, making the package available to users.
+
+
+GitHub Actions CI/CD Pipelines
+------------------------------
+
+The project utilizes four primary GitHub Actions workflows:
+
+1. **Feature Branch Validation**:
+
+   - **Workflow File**: `code_quality.yml`
+   - **Trigger**: Initiates on pull requests targeting the `dev` branch from feature branches (e.g., `featureXXX`).
+   - **Functionality**:
+
+     - Runs static code analysis using Qodana.
+     - Ensures code quality and standards compliance before merging.
+     - Executes within an isolated environment to verify quality without modifying the branch.
+     - Validates that the code aligns with development standards before it can be integrated into `dev`.
+
+2. **Alpha Branch Validation**:
+
+   - **Workflow Files**: `CI.yml` and `build-test-package.yml`
+   - **Trigger**: Runs on any push to the `alpha` branch.
+   - **Functionality**:
+
+     - Executes tests across different Python versions to ensure compatibility.
+     - Uploads test coverage reports to Codecov, maintaining accountability for test quality.
+     - Builds the package, installs it in a virtual environment, and runs tests to confirm the package's standalone functionality.
+     - Acts as the final pre-production gate, validating that `alpha` is stable before being merged into `master`.
+
+3. **Production Release to PyPI**:
+
+   - **Workflow File**: `publish-to-pypi.yml`
+   - **Trigger**: Executes upon tagged releases to `master`.
+   - **Functionality**:
+
+     - Builds the package into source and wheel distributions.
+     - Publishes the package to PyPI, ensuring the release is available in production.
+     - This workflow guarantees that only a stable, tested, and tagged version is deployed to PyPI.
+
+4. **Build and Install Test for Package Validation**:
+
+   - **Workflow File**: `build-test-package.yml`
+   - **Trigger**: Activates on any push or pull request to `alpha`.
+   - **Functionality**:
+
+     - Builds the package and verifies that it can be installed in an isolated environment.
+     - Ensures the package can run independently of the source, verifying import dependencies and package structure.
+     - Provides confidence that the package can be distributed and used without issues related to build or installation.
+
+By following this CI/CD strategy, the project maintains high code quality, consistent testing, and reliable releases with minimal manual intervention.
