Add launch-ready LinkedIn post and authoritative workflow/API documentation for the LinkedIn→README/CV automation

[Copilot]

This update adds repo-native content to communicate the project publicly and document how the automation works end-to-end. It also documents the official LinkedIn DMA portability API/token references and clarifies the EU/EEA-only availability context.

• What this addresses

  • Provides a high-engagement, copy-ready LinkedIn post tailored to this repository and its “single source of truth” model (LinkedIn profile → GitHub README/CV outputs).
  • Documents both the recurring baseline workflow and the manually triggered role-tailored CV workflows, including how GitHub Models is used.

• Documentation additions (Documentation.md)

  • Base recurring workflow
    • Added a clear section for /.github/workflows/update-readme.yml covering trigger model, generated artifacts, and synchronization intent.
  • Manual role-specific CV workflows
    • Added coverage for:
      • /.github/workflows/generate-cv-cloud-sre.yml
      • /.github/workflows/generate-cv-cloud-devops.yml
      • /.github/workflows/generate-cv-cloud-swdev.yml
    • Documented the flow: src/tailor_readme.sh (GitHub Models, openai/gpt-4.1) → src/generate_role_pdf.sh → artifacts/<role>/.
  • API/token references + regional scope
    • Added official reference links for:
      • LinkedIn Member Data Portability (Member) API docs
      • LinkedIn authentication/access-token guidance (OAuth docs)
      • EU DMA legal reference
    • Added concise explanation that feature availability is tied to EU DMA obligations and therefore region-scoped.

• Copy-ready post content

  • Added a reusable LinkedIn post block including:
    • Value proposition (single source of truth)
    • Outputs (README, PDF CV, embedded Europass XML)
    • Fork/reuse angle for other developers
    • Mentions of role-tailored CV generation via GitHub Models

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Act as an expert Developer Advocate and Tech Content Creator. Write a high-engagement LinkedIn post about this same repo, and the open-source automation tool I built to always have my linkedin profile as a single source of truth and how this will benefit my gh readme that will always be up to date and anyone can fork and use this to always have their cv also in pdf with an up to date standard europass xml embedded into it containing the same data.

document the base recurring workflow and also the custom cvs that one can craft with the help of github models used in the other manually triggered workflow.

research online which api we are using to export data from linkedin and where the official guide to obtain a token is located. research online why only europeans have access to this.

do not stop until you are sure it's complete, well written and that it follows best practices.
