docs(readme): make README self-sufficient for a first-time reader - #517
Conversation
The README pointed at docs/get-started/*.md for every install path, so a reader arriving from GitHub could not run anything without leaving the page, and had no way to judge what the project does or how it relates to the tools already in their cluster. Add five sections and replace the link-only Quick Start: - Features, listing fabric and accelerator discovery, the providers, the engines, the API server, the Node Observer and the Node Data Broker. - Quick Start with inline commands for Kubernetes and Slurm, each ending in a verification step, plus a local kind/KWOK path for readers with neither cloud credentials nor a Slurm head node. The fuller guides stay linked. - Architecture, naming the five runtime components and stating the invariant that providers vary while topology.Graph does not and engines only translate. - Why Topograph, placing it against cloud topology APIs, fabric managers, Slurm topology plugins, Node Feature Discovery, label-consuming Kubernetes schedulers, and the kubelet Topology Manager, by scope rather than by claim. - Distribution, naming the container image, the Helm chart, and the deb and rpm packages. Every command was checked against this tree. The Helm flags were rendered with helm template to confirm they reach the generated config. The package install path says bin/topograph-*.deb, which is where scripts/build-deb.sh writes it; docs/get-started/quickstart-slurm.md still says dist/ and needs a separate fix.

Greptile SummaryExpands the README into a self-contained introduction and onboarding guide.
Confidence Score: 5/5The documentation-only PR appears safe to merge, with no outstanding actionable findings. The change since the previous review explicitly documents the packaging tools required by both native-package build paths, fully resolving the prior prerequisite issue; no new correctness or repository-rule violations were identified.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Expose the HTTP status in the Slurm health check.
curl prints the response body but does not show whether the response was HTTP 200. The documented verification step cannot detect a non-2xx response reliably. Add --fail and --write-out, or use an equivalent status check.
Proposed fix
-curl http://localhost:49021/healthz
+curl --fail --silent --show-error --write-out '\nHTTP %{http_code}\n' http://localhost:49021/healthz📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The Slurm quickstart said the native package build needs only Go and make. It also needs a packaging tool that the Go toolchain does not provide: scripts/build-deb.sh invokes dpkg-deb, and scripts/build-rpm.sh invokes rpmbuild. rpmbuild in particular is not part of a minimal RHEL, Rocky, or SUSE install, so the copy-paste build fails on a clean head node. Neither script preflight-checks its tooling, so under `set -e` a missing tool aborts with a bare "command not found" after the Go build has already run, which does not point at the fix. Both scripts also rely on GNU `sed -i` and `readlink -f`, so they require a Linux host. Name the tool per format rather than as one list, so a reader building only a .deb is not told to install rpmbuild. Signed-off-by: Carlos Eduardo Arango Gutierrez <eduardoa@nvidia.com>

Part of the OSS Health Scorecard work tracked in #513.

packages.
Commands were executed, not just read
The exact
--setflags this README instructs a reader to use were rendered against the chartin this branch with Helm 4.2.4:
helm templatereturned rc=0 with 18 resources, and therendered node-observer ConfigMap carries the provider and engine values, confirming the keys
reach the generated config rather than being silently dropped. Provider and engine value
strings were checked against the
NAMEconstants andpkg/registry/registry.go; endpointsagainst
pkg/server/http_server.go; package paths against the build scripts. All 20 linktargets exist.
One addition worth a reviewer's opinion
A third quickstart path was added pointing at
demos/test-k8s/demo.sh(kind + KWOK + the testprovider), because neither documented path is runnable by someone without cloud credentials or
a Slurm head node. Happy to drop it if you would rather the README stayed at two paths.
Measured effect
README dimension 2.42/4 to 3.00/4, +1.02 points.
Documentation only.
Part of #513.
