+
+## What This Is
+End-to-end testing framework for Managed services for OSD/ROSA. It is currently applied as a test framework in ROSA nightly CI jobs, OSD operator CICD pipelines and on-demand test schedules such as gap analysis. 
+
+## Core Test Workflow
+1. Load config (CLI flags → env vars → custom YAML → defaults)
+2. Provision cluster (or use existing via CLUSTER_ID)
+3. Health check (optional)
+4. Run tests
+5. Upgrade (optional)
+6. Cleanup (optional)
+
+## Key Files
+- `pkg/common/config/config.go` - All configuration options (START HERE)
+- `cmd/osde2e/main.go` - Entry point
+- `pkg/common/providers/` - Cloud provider implementations (OCM, ROSA)
+- `pkg/common/cluster/healthchecks/` - Health validation logic
+- `internal/llm/` - LLM/AI integration (Gemini)
+
+## Common Patterns
+
+### Configuration
+- Everything in `config.go`: const key + env var + default
+- Access via `viper.GetString(config.SomeKey)`
+- Precedence: CLI > Env > Custom YAML > Default
+
+### Providers
+- Interface: `pkg/common/spi/`
+- Registered in `main.go`
+
+
+### Authoring new platform component tests
+- To add new component tests: Use boilerplate (README https://github.com/openshift/boilerplate/blob/master/boilerplate/openshift/golang-osd-e2e/README.md), not here
+
+### Logging
+- Use `logr`/`klog`, not `fmt.Println`
+- Structured logging preferred
+
+
+## Quick Tips
+1. Config changes? Edit `config.go` only
+2. Provider logic? Use SPI abstraction
+3. Integration test failures? Check credentials/env vars
+4. Always use `gofumpt`, not `gofmt`
+5. Check git status before committing
+
+## Environment
+- See `config.go` for complete list
+
+## Architecture
+```
+osde2e
+├── cmd/osde2e/          # CLI commands (provision, test, cleanup, krknai)
+├── pkg/common/          # Core logic (config, providers, helpers)
+├── internal/            # LLM analysis (llm, sanitizer, prompts)
+└── test/                # Standalone Ginkgo test suites
+```
+
+## Interacting With The Code
+- Always stick to existing design patterns in code
+- Keep new code simple and concise
+- Keep pull requests small
+- Always reuse existing code
+- Use go language best practices
+- Prefer implementing existing or new interfaces, don't write extensive procedural logic
+- Extend test helper functionality in https://github.com/openshift/osde2e-common, not here
+
+## Before You Commit
+```bash
+gofumpt -w .        # Format (not gofmt!)
+make build      # Compile
+go test ./... -v    # Test (integration tests need credentials)
+```
+
+## E2E Testing instructions
+- Do not allow e2e test unless following env vars are set: AD_HOC_TEST_IMAGES|CLUSTER_ID|OCM_CLIENT_ID|OCM_CLIENT_SECRET|AWS_ACCESS_KEY_ID|AWS_SECRET_ACCESS_KEY
+- To run via cli:
+```bash
+go run cmd/osde2e/main.go test  --skip-health-check --skip-must-gather --skip-destroy-cluster --configs=rosa,sts,stage,ad-hoc-image"
+````
+- To run via IDE debugger, if IDE is VSCode, use configs/local/example-launch.json; if IDE is GoLand, use configs/local/example-e2e.run.xml
+
+## Unit Testing instructions
+- Add or update for unit tests for concrete implementation changes and new functionality, even if nobody asked.
+- Fix any test or type errors until the whole suite is green.
+
+## PR instructions
+- Title format: [<jira-ID>] <Title>
