About This Template
Documentation that respects your time
Codex is a developer-docs template built around the layout that actually works for technical writing — sidebar nav, scrolling content, sticky table of contents on the right. Search works the moment you deploy. Callouts render. Code blocks have copy buttons. The feedback widget posts to a real backend.
Eight pages of real content
Not lorem ipsum: an Introduction, Quick Start, Installation guide, two Concept pages (Authentication, Data fetching), two API References (REST, Webhooks), and a Changelog. Every page is fully wired — sidebar active state, breadcrumb, TOC anchors, code samples in real languages, and a feedback widget at the bottom.
Built for the developer aesthetic
Mona Sans display, JetBrains Mono code, teal accent. Dark by default (Carbon theme), with Paper and Mono variants for daytime reading and high-contrast preferences. Every primitive — search, callouts, feedback — works the moment you clone the template.
