A little reading.
A little more confidence.
Start at lesson one, or look for an answer to a specific question.
Meet Codex: start with one small task
Learn how Codex fits into your work, then choose a task whose result you can check.
Install and sign in: find Codex on your desktop
Use the official installation instructions, then find the Codex workspace.
Choose a workspace: give your files a clear home
Use a separate practice folder and confirm its location before creating files.
Write a clear request: goal, context, constraints, and checks
Use a copyable prompt to make your expectations concrete.
Build your first personal webpage
Send a request, open the result, and make one targeted revision.
Check and improve: verify what “done” means
Review the content, interactions, layout, and file location.
Field notes: how this handbook was built
From the target reader to three prototypes and the chosen design, a record of the initial local build.
A recorded walkthrough: from a request to Lin’s webpage
Inspect the first draft, one planned revision, desktop and mobile screenshots, and source files.
How far can Codex take a first personal webpage? One case review
Examine a draft, one revision, and three viewport checks without overstating what this single run proves.
Our review method: make the process and result inspectable
A transparent recording method, with one case analysis and no standardized scores or rankings.
Troubleshooting: locate the problem, then continue
Give useful feedback when files are missing, changes do not appear, or the task drifts.
Revise an existing webpage with Codex: request, compare, and check
Use the recorded Lin revision to practice scoping changes, preserving a baseline, giving feedback, and checking results.
