-## Current Status vs Mandatory Scope
+## Delivered Scope
 
-Implemented:
+Mandatory:
 
 - 1D and 2D ndarray support.
 - Creation functions (`array`, `zeros`, `arange`).
 - Addition operations (`add`, `addInPlace`).
-- Scalar addition and `sum()` reduction.
 - Reshape with validation.
-- Docker containerization with CI/CD pipeline.
-- Infrastructure as Code for GCP deployment.
+- NumPy-like display.
+
+Optional / bonus (difficulty level in brackets):
+
+- Scalar addition and `sum()` reduction — library extensions.
+- Maven SNAPSHOT publishing to GitHub Packages, gated by 70% coverage [2].
+- Multi-stage Docker image published to GHCR with semver/sha tags [3].
+- Infrastructure as Code (Terraform + Ansible) for GCP deployment [4].
+- SonarQube static analysis integrated in CI with quality gate [3].
+- CI/coverage badges and GitHub Pages documentation site [1].
 
-In progress / next:
+## Feedback
 
-- Final quality/readability cleanup.
-- Final documentation polishing and report completion.
+This project was a good learning experience for us. We learned that having a working pipeline early saves a lot of time later, and we learned how the use tools such as terraform & ansible along the way.
 
-## Feedback and Retrospective (Living Section)
+What went well:
 
-What worked well so far:
+- CI + tests helped us avoid regressions.
+- Small PRs made reviews easier.
+- Docker made demo execution consistent across machines.
+- Terraform + Ansible split infra creation and app deployment clearly.
 
-- Small PR scope reduced merge risk.
-- Review-first workflow caught shape/metadata issues early.
-- CI + tests made refactoring safer.
+What was harder:
 
-What to improve next:
+- Covering edge cases (2D behavior, reshape validation) with clean tests.
+- Keeping feature branches up to date with `main`.
+- Initial cloud setup (credentials, IAM roles, SSH keys).
 
-- Add more explicit edge-case tests for some 2D operations.
-- Keep branch updates synchronized with `main` to reduce conflict churn.
-- Start working on bonus options once mandatory scope is fully stable.
+What we can improve next:
 
-This section will be updated at each milestone.
+- Add moretests (edgecases) for 2D operations
+- Add an automatic changelog for releases.
+- Add a PR template...
