+
+## Baseline
+
+- Promotion: Move things from one env to another
+- Options: Sequentially or both
+- Challenge: Env differences
+- Challenge: How do we link our promotion tasks?
+
+### GitOps
+
+- Declarative: YAML, JSON, XML (Not helm or kcl or anything else)
+- Versioned and immutable: Git
+- Pulled automatiocally: No wirte access from cluster
+- Continously reconciled: Maintain parity between desired and actual state
+
+### Rules
+
+- Part of SLDC
+- Declarative
+- Versioned and immutable
+- Pulled automatiocally
+- Continously reconciled
+
+## Workflows
+
+### Manual
+
+1. Deploy
+2. Run tests
+3. Push to next stage
+4. Test again or roll back
+
+### Manual with gitops
+
+1. Update manifest 
+2. Push to git
+3. Test
+4. Next stage
+
+Problem: Eventual consistency makes the process async instead of sync (important for tests)
+
+### Generic workflows
+
+1. Dev: Bump, push
+2. QS: Wait for success of 1 (how?), do the same
+3. Prod: Wait for success of 2 (how?)
+

+
+## Tools
+
+### Extend your standard CI
+
+
+Not async, risk of flapping, either blindly trust the state or break the pull-principle by running argo sync or kubectl apply
+
+### AppSets Progressive Sync
+
+- Built in to Application Sets (alpha)
+- Targeting by label, promotes everything
+- Not supported with autosync, bechause it basically manually triggers sync one after another
+- Changes from git have to be manually triggered
+
+### Image updater
+
+- Subscribe to semver based image updates and write them to kubernetes and/or git
+- You have to implement promotions via image naming schemes
+
+TODO: Steal flowchart
+
+### Kargo
+
+- Freight: Artifact or manifest versions to promote
+- Stage: ArgoCD Apps
+
+TODO: Steal flowchart
+
+### Telefonistka
+
+- IaC Agnostic tooling
+- Idea: Watch folder contents and copy contents to new folder
+- Pretty mutch a bundeled CI-Script
+
+TODO: Draw your own chart
+
+### Codefresh GitOps
+
+> This is one of the speaker's tools
+
+- Product: Applications with relationships
+- Env: Any cluster and/or namespace
+- Promotion: CRD for policy (when does it happen, what get's validated)
+- Promotions can happen manually or automated via commit/pr
+- BAsed on argo workflows
+
+### GitOps Promoter (Intuit)
+
+- Define Manifests once and hydrate them later
+- Sourcehydrator: Argocd feature that handels the rendering and commits it to a new dedicated branch (one branch per stage)
+- The Branches are the branches used by argo, e.g. `environments/dev` get's watched by the dev cluster
+- Changes result in environment proposal branches, PR get's oppened, PR checks run, when PR requirements are met (Tests), it will merge them into the real env branches
+
+TODO: Steal Pattern
+
+## Overview of the philosopies
+
+Artifact Oriented: Imageupdater, Kargo
+Define Manifests once: AppSets Progessive Sync, GitOps Promoter
+Deff and workflow: CI, Codefresh
+
+TODO: Steal from slides
+
+## Best practives
+
+- Can you recover from git at any point? No -> Do better
+- Does git reflect what's deployed without looking?
+- Does this enable SDLC?
+- Interfaces in folders, not branches? -> Branches may get crowded
