Add “Adding Custom Components” under the “Custom Components” SDK sidebar entry. The guide shows component authors how to publish a Go library in their own repository with direct constructors and Register* helpers; consuming apps import the library and register on their own configurl provider container.

The runnable example separates components/delay.go, components/timeout.go, and the consuming app's main.go. Constructors own the behavior and validation, while registration helpers parse delay:<time> and timeout:t=<time>&error=<msg>. A direct-use helper demonstrates constructing the same stack without configuration strings. The guide also covers wrapper order, encoding, registration scope, and links to the key extension APIs.

Validation:

• Fresh review by a clean-context subagent acting as a Go developer unfamiliar with Outline: no remaining clarity or conceptual issues.
• All documented commands executed in a fresh module using the exact three extracted files; success, timeout, reversed composition, and invalid-option outputs matched.
• Nine race-enabled checks passed, including the extracted direct-use helper, constructor validation, deadline/cancellation behavior, composition, encoding, and registration scope.
• English/German production builds and all 17 translation checks passed; verified rendered article title, sidebar label, code filenames, and API links.
• Example pinned to SDK x v0.2.2 and core v0.0.22; local Go 1.25.5 and Node 24.20.0. git diff --check passed.

The optional TypeScript check has three existing Cannot find namespace 'JSX' errors in src/pages/index.tsx (lines 7, 27, 75), previously reproduced on the unchanged base revision.

Phase 1 of the configuration extension documentation project. SmartDialerOptions API changes and the Mobileproxy extension article remain separate follow-up phases.

nice, thanks for adding this!

Unless comments I made it is nice! Publishing the full code in a repo with the variants could be helpful too as a starting point for readers / implementers.
