+### Factory URLs
+
+Eclipse Che supports one-click workspace creation via factory URLs.
+Navigate to the URL and Che creates a workspace automatically.
+
+By default, Che uses `devfile.yaml` at the repository root:
+
+```
+https://<che-host>/#https://github.com/unbound-force/containerfile
+```
+
+To use the dynamic devfile (UDI + postStart), append the devfile path:
+
+```
+https://<che-host>/#https://github.com/unbound-force/containerfile?devfilePath=devfile-dynamic.yaml
+```
+
+Replace `<che-host>` with your Eclipse Che instance hostname
+(e.g., `che.example.com`).
+
+### Red Hat Dev Spaces
+
+Expected to be compatible with Red Hat OpenShift Dev Spaces. Not yet
+tested in a Dev Spaces environment.
+
+Known differences from open-source Eclipse Che:
+
+- **Per-user namespaces** — Dev Spaces creates a Kubernetes namespace
+  per user automatically
+- **OpenShift OAuth** — SSO via OpenShift identity provider instead of
+  standalone Keycloak
+- **Image registry** — container images must come from a trusted
+  registry (quay.io is fine)
+
+For more information, see the
+[Red Hat Dev Spaces documentation](https://developers.redhat.com/products/openshift-dev-spaces/overview).

+## Context
+
+The dynamic devfile's `install-tools` command references a local script
+at `/projects/scripts/install-uf-tools.sh` which fails when the cloned
+project isn't the containerfile repo. The README lacks factory URL
+documentation and Red Hat Dev Spaces notes.
+
+See proposal.md for full motivation and constitution alignment.
+
+## Goals / Non-Goals
+
+### Goals
+- Make `devfile-dynamic.yaml` work with any cloned project
+- Document factory URL patterns for one-click workspace creation
+- Document Red Hat Dev Spaces compatibility (honestly — tested or not)
+
+### Non-Goals
+- Modifying `devfile.yaml` (custom image variant already works)
+- Changing the install script itself (`scripts/install-uf-tools.sh`)
+- Adding credential injection documentation (tracked in Issue #4)
+- Adding devfile schema validation to CI
+
+## Decisions
+
+### D1: Curl from GitHub raw URL instead of local script
+
+**Decision**: Replace the local file reference with:
+```bash
+curl -fsSL https://raw.githubusercontent.com/unbound-force/containerfile/main/scripts/install-uf-tools.sh | bash
+```
+
+**Rationale**: This is the simplest approach — no external tooling needed,
+same pattern already used for OpenCode installation (`curl | bash`).
+The URL points to the `main` branch so it always gets the latest script.
+If the repo is private, the URL won't work — but this repo is public.
+
+**Alternatives rejected**:
+- Inline the script in the devfile: bloats the YAML, duplicates logic,
+  maintenance burden
+- Download from a release artifact: adds versioning complexity for a
+  script that should always be latest
+
+### D2: Factory URL documentation scope
+
+**Decision**: Document the factory URL pattern with examples for both
+`devfile.yaml` (default) and `devfile-dynamic.yaml` (explicit path).
+
+**Rationale**: Che uses `devfile.yaml` at repo root by default. To use
+`devfile-dynamic.yaml`, the factory URL needs `?devfilePath=devfile-dynamic.yaml`.
+Both patterns should be documented.
+
+### D3: Dev Spaces honesty policy
+
+**Decision**: Document Dev Spaces as "expected to be compatible" with
+known differences called out, but do not claim "tested" unless actually
+verified in a Dev Spaces instance.
+
+**Rationale**: Constitution IV (Executable Truth) requires documentation
+to be honest. We haven't tested in Dev Spaces, so we say so.
+
+## Risks / Trade-offs
+
+| Risk | Impact | Mitigation |
+|------|--------|------------|
+| GitHub raw URL unavailable (rate limiting, outage) | Medium — postStart fails | Devfile error message tells user what to check |
+| Script changes on main break existing workspaces | Low — script is stable | Version pinning via commit SHA available if needed |
+| Dev Spaces has undocumented incompatibilities | Low | Honest documentation; users can file issues |

+## Why
+
+The CDE devfiles and documentation have three gaps:
+
+1. **Dynamic devfile postStart fails for non-containerfile repos** —
+   `devfile-dynamic.yaml` references `/projects/scripts/install-uf-tools.sh`
+   which only exists if the containerfile repo itself is cloned. If an
+   engineer clones their own project (e.g., `unbound-force/gaze`), the
+   postStart fails because the script isn't there.
+
+2. **No factory URL documentation** — Eclipse Che supports one-click
+   workspace creation via factory URLs
+   (`https://che.example.com/#https://github.com/...`), but this isn't
+   documented. Engineers don't know they can create a workspace directly
+   from a GitHub URL.
+
+3. **No Red Hat Dev Spaces notes** — The devfiles should work with
+   Red Hat OpenShift Dev Spaces (enterprise Che), but compatibility
+   is undocumented and known differences aren't called out.
+
+Ref: [Issue #5](https://github.com/unbound-force/containerfile/issues/5)
+
+## What Changes
+
+### devfile-dynamic.yaml
+
+Replace the local script reference with a curl download from the
+containerfile repo's main branch on GitHub. This removes the
+dependency on the containerfile repo being the cloned project.
+
+### README.md
+
+- Add factory URL documentation with patterns and examples
+- Add Red Hat Dev Spaces compatibility notes
+
+## Capabilities
+
+### New Capabilities
+- `factory-url`: One-click workspace creation via Che factory URL documented
+- `remote-install`: Dynamic devfile downloads install script from GitHub (no local dependency)
+
+### Modified Capabilities
+- `install-tools` (devfile-dynamic.yaml): Changes from local file reference to curl-from-GitHub download
+
+### Removed Capabilities
+- None
+
+## Impact
+
+- **devfile-dynamic.yaml**: `install-tools` command rewritten to use curl
+- **README.md**: New "Factory URLs" and "Red Hat Dev Spaces" sections
+- **No Containerfile changes**: The install script itself is unchanged
+- **No CI changes**: Devfile modifications don't affect container image builds
+
+## Constitution Alignment
+
+Assessed against the containerfile project constitution (v1.0.0).
+
+### I. Composability First
+
+**Assessment**: PASS
+
+The curl-from-GitHub approach improves composability: the dynamic
+devfile no longer requires the containerfile repo to be the cloned
+project. Any project can use `devfile-dynamic.yaml` by copying it
+into their repo — the install script is fetched at runtime.
+
+### II. Security Through Isolation
+
+**Assessment**: N/A
+
+No security model changes. The curl-from-GitHub pattern has the
+same risk profile as the existing OpenCode curl installer (already
+mitigated by container isolation per Constitution II).
+
+### III. Reproducible Builds
+
+**Assessment**: N/A
+
+No Containerfile or CI changes.
+
+### IV. Executable Truth
+
+**Assessment**: PASS
+
+README documentation will be updated to match the new devfile
+behavior. Factory URL patterns will be verified. Dev Spaces
+compatibility will be documented honestly (tested vs untested).

+## ADDED Requirements
+
+### Requirement: Factory URL Documentation
+
+README.md MUST document Eclipse Che factory URL patterns for one-click
+workspace creation, including:
+- Default pattern (`https://che.example.com/#<repo-url>`)
+- Explicit devfile path for the dynamic variant
+- At least one concrete example URL
+
+#### Scenario: Engineer creates workspace via factory URL
+- **GIVEN** an engineer with access to an Eclipse Che instance
+- **WHEN** they navigate to `https://che.example.com/#https://github.com/unbound-force/containerfile`
+- **THEN** Che creates a workspace using `devfile.yaml` from the repo root
+
+#### Scenario: Engineer uses dynamic devfile via factory URL
+- **GIVEN** an engineer who wants the UDI-based dynamic devfile
+- **WHEN** they append `?devfilePath=devfile-dynamic.yaml` to the factory URL
+- **THEN** Che creates a workspace using `devfile-dynamic.yaml` instead
+
+### Requirement: Red Hat Dev Spaces Documentation
+
+README.md MUST include a "Red Hat Dev Spaces" section noting:
+- Expected compatibility status (tested or untested — be honest)
+- Known differences from open-source Eclipse Che
+- Link to Dev Spaces documentation
+
+#### Scenario: Engineer looks for Dev Spaces guidance
+- **GIVEN** an engineer using Red Hat OpenShift Dev Spaces
+- **WHEN** they read the README
+- **THEN** they find guidance on compatibility and any known differences
+
+## MODIFIED Requirements
+
+### Requirement: Dynamic Devfile Install Script
+
+The `install-tools` command in `devfile-dynamic.yaml` MUST download
+`install-uf-tools.sh` from the containerfile repo's GitHub raw URL
+instead of referencing a local file path. The download MUST use
+`curl -fsSL` with the `main` branch URL.
+
+Previously: The command referenced `/projects/scripts/install-uf-tools.sh`
+which only exists when the containerfile repo is the cloned project.
+
+#### Scenario: Dynamic devfile with a non-containerfile project
+- **GIVEN** an engineer who clones `unbound-force/gaze` into a Che workspace
+  using `devfile-dynamic.yaml`
+- **WHEN** the postStart event runs `install-tools`
+- **THEN** the script is downloaded from GitHub and tools are installed
+  successfully
+
+#### Scenario: GitHub raw URL is unavailable
+- **GIVEN** a workspace where `raw.githubusercontent.com` is unreachable
+- **WHEN** the postStart event runs `install-tools`
+- **THEN** the curl command fails with a clear error (exit 1) and the
+  workspace starts without UF tools installed
+
+## REMOVED Requirements
+
+None.
