Glossary, troubleshooting, and what’s next

# Glossary

App: A piece of software that helps someone do a job. Your task-list website is an app.

Browser: An app used to open websites, such as Safari or Chrome.

Button: Something on a page that you click to make an action happen.

Codex: The assistant you use to create, change, check, and publish software by giving it instructions.

Cloudflare Pages: A service that can put a website online so people can open it with a link.

Deploy: Put an updated version of a website online. In this course, publishing and deploying mean nearly the same thing.

Domain: A web address that you own, such as mytasks.com.

Folder: A place on your computer that holds related files together.

GitHub: An online home for project files and their saved history.

Link: Clickable web address that opens a page.

Local preview: A version of your website that opens on your own computer before you publish it. Other people cannot open it.

Permission prompt: A message asking whether Codex may do something, such as create files or run a local preview.

Private link: A link intended for people you choose to share it with.

Project: The folder and files that belong to one app.

Public link: A link that anyone with the link may be able to open.

Publish: Put a website online so it can be opened with a link.

Refresh: Ask a browser to load the current page again. Click the circular arrow. Mac users: you can also press Command + R. Windows users: you can also press Ctrl + R.

Task list: A list of things you need to do.

Text box: An empty area on a page where you can type words. You may also hear it called an input.

Website: A set of web pages that open in a browser. In this course, your app is a small website with one main page.

# Final congratulations

Congratulations! You have done much more than make a task list. You have practised the core way to build software with Codex: explain a goal, ask for one small change, check the result, and decide what happens next.

You now have experience planning, creating, testing, improving, and publishing a useful app. You do not need to write code yourself to be a software creator. Your job is to guide Codex clearly and use your judgement to check its work.

Three beginner projects to try next

A daily habit tracker: Add habits such as “Drink water” or “Go for a walk,” then tick them off each day.
A packing-list website: Create lists for holidays, camping, or moving house, with tick boxes and remove buttons.
A simple study planner: Add subjects and study tasks, then mark each task as finished.

Start your next project the same way you started this one: ask Codex for a short plan, approve it, and build one small feature at a time.

# Revision changelog

Added Before You Begin so learners know the computer, internet, browser, sign-in, local-preview, and permission expectations before the first module.
Renumbered the course from Module 0 to Module 11 so the prompting foundation stays clearly separate from the 11 build-and-publish modules.
Reworked the early project modules so Codex recommends a safe project location and the learner approves it, instead of assuming a Documents folder.
Added a local-setup check before the first page so learners do not assume their computer can run a website without preparation.
Added a course-wide recovery message for when Codex's instructions differ from the course.
Made the learner's own browser test the final check throughout; Codex can review, but it does not replace hands-on confirmation.
Rewrote sharing and publishing steps to ask what options are available in each learner's Codex setup before making promises about private or public links.
Added the browser-storage note so learners understand why people who open a shared link begin with an empty task list.
Added glossary entries for local preview and permission prompt.
Kept the existing small-step structure, plain language, troubleshooting pattern, checklists, and “What just happened?” explanations so the course continues to feel like one instructor wrote it.
Replaced the single publishing lesson with GitHub, Cloudflare Pages, domain, and live-update lessons so learners can save, publish, and maintain their work one safe step at a time.
