This post contains some notes on using Karpathy’s LLM Wiki to plan a trip. It uses Claude Code and Obsidian.

Prerequisites

Claude Code

  1. Get an Anthropic subscription. I started with the $20/month pro plan.

  2. Install Claude Code terminal version per https://code.claude.com/docs/en/overview

     curl -fsSL https://claude.ai/install.sh | bash
 echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc && source ~/.bashrc

  3. Open Claude Code

     claude

  4. Setup Claude

    • Dark mode
    • Claude account with subscription

Obsidian

  1. Download and install from https://obsidian.md/
  2. Create new vault: ~/src/llm-wiki-2026-summer-trip
  3. Install chrome extension: https://chromewebstore.google.com/detail/obsidian-web-clipper/cnjifjpddelmedmihgijeibhnjfabmlf?hl=en&pli=1

Version Control

  1. Create repository in https://bitbucket.org/ylxiong/workspace/overview/

    • Name: llm-wiki-2026-summer-trip
    • Include a README: No
    • Include .gitignore: No

  2. Connect with local directory

     cd ~/src/llm-wiki-2026-summer-trip
 git init
 git remote add origin git@bitbucket.org:ylxiong/llm-wiki-2026-summer-trip.git

Steps

  1. Create folder structure

     llm-wiki-2026-summer-trip
 |- raw/
 |- templates/
 |- wiki/
 |- Welcome.md

  2. Add CLAUDE.md

  3. Add content to raw/ folder, e.g. flight tickets (printed email)

  4. Ask Claude to update the wiki

     > I just added some new sources to the raw folder. Please read it and update the wiki.

  5. Repeat previous two steps with more content:

    • Hotel reservation (PDFs downloaded from hotels.com)
    • Rental car reservation (PDF downloaded from expedia.com)
    • Cruise trip tickets and excursions
