Gemini CLI and Warp: beginner setup and app tutorial

This beginner tutorial follows a Gemini CLI coding assistant workflow, starting with terminal basics and ending with a single-file web app. The speaker explains directory commands, then uses Warp to help install Gemini CLI and resolve missing dependencies. Warp is presented as a terminal with built-in AI assistance, available for Mac, Linux, and Windows.

The walkthrough uses Google login. The speaker describes this route as providing free account access and notes that heavier use can reach limits. They distinguish it from API-key billing, but give no specific quotas.

Before requesting code, the speaker asks Gemini's chat interface to draft a product requirements document for an animated tree page. They export the document through Docs, save it as Markdown in a project folder, and ask Gemini CLI to build from it. The example produces a tree animation with cherry blossoms. The speaker calls this an unusually error-free build, rather than a typical result to expect.

For revisions and runtime errors, the tutorial recommends sending screenshots back to the coding tool with a plain-English request. It also covers voice input: the speaker describes oto as Mac-only software that transcribes locally, and mentions Superwhisper for Mac and Windows. That local processing claim concerns oto, not the Gemini CLI workflow.
