The shortest reliable path to a working R2 Desk Pro workflow.
Follow this sequence instead of jumping between random pages. It gets a new buyer from overview to trial to a stable operating baseline with the least support debt.
Understand the full Private Beta product surface first
Start with the product overview for positioning, capability matrix, launch offer, store links, and the trial-to-license path.
Open stepMove from install to first working bucket operation
Quickstart covers install, EULA acceptance, the 7-day trial, paid licensing, vault setup, first profile validation, and the first smoke check.
Open stepUse the correct Windows, macOS, or Linux install path
Platform notes cover installer types, runtime prerequisites, OS-specific warnings, and support boundaries by desktop variant.
Open stepKnow the vault and licensing rules before the trial ends
Security, vault, and licensing explains keychain storage, EULA gating, the 7-day trial, and one activation per paid license.
Open stepDesktop platform guidance is explicit about support and installer warnings.
Platform behavior is documented separately because installers, runtime prerequisites, native security warnings, and support posture are not identical across the three desktop targets.
Windows SmartScreen and macOS Gatekeeper warnings are documented up front so beta install friction does not turn into avoidable refunds or support escalations.
Windows
- NSIS .exe and .msi release artifacts
- WebView2 runtime required
- SmartScreen unknown-publisher warning documented for beta installs
macOS
- DMG release path and local build distinctions
- Keychain prompts and native file access behavior
- Gatekeeper unidentified-developer warning documented for unsigned beta builds
Linux
- Ubuntu/Debian .deb support plus AppImage fallback
- WebKitGTK, AppIndicator, and desktop-environment requirements
- Non-Debian distributions treated as best-effort
Find the guide by the job you are actually doing.
The product is not one screen. The docs are organized around real operator tasks: trial, licensing, bucket administration, transfer execution, preview and delivery, settings, security, and release engineering.
Open the guide for the task in front of you instead of skimming every page and hoping the right answer is somewhere in the middle.
Run bucket administration from one desktop workspace
Bucket create/delete, location hints, storage class, jurisdiction, domains, lifecycle, notifications, and object operations.
Open guideRun transfers and sync safely
Queue model, retry visibility, multipart handling, resume support, conflict preflight, dry runs, and sync history.
Open guidePreview assets and ship delivery changes
Inline preview, signed URLs for GET/HEAD/PUT/DELETE, public URL mapping, cache purge, cost analysis, and live metrics.
Open guideTune the product for daily use
Theme, density, transfer runtime, preview thresholds, URL defaults, cost assumptions, and vault policy.
Open guideUnderstand security and licensing
Vault behavior, keychain storage, EULA acceptance, the 7-day trial, paid licensing, and update checks.
Open guideBuild, package, and verify releases
Desktop and website commands, installer output, CI expectations, and production build discipline.
Open guideCommon install and workflow failures have dedicated entry points.
The goal is to stop vague support requests before they start. If the issue is recurring, the docs point you to the exact failure tree or operator rule.
A useful docs hub routes users to the right diagnostic path first. It does not ask support to sort setup drift from real defects by hand.
Windows says Unknown publisher
Use Quickstart and Troubleshooting for the SmartScreen guidance before escalating the beta installer path as a defect.
Open pathmacOS says the app is from an unidentified developer
Troubleshooting documents the Gatekeeper/Open flow for unsigned DMG installs during beta.
Open pathUploads or sync behave unpredictably
Transfers and sync covers queue states, retrying, multipart thresholds, resume behavior, and cancellation semantics.
Open pathDelivery, URLs, or metrics do not line up
Preview, URLs, cache purge, and cost analysis explains signed/public mapping, purge requirements, and live metrics context.
