# Script to migrate from obsidian readwise to logseq readwise
# 1. Create a new logseq vault and sync your readwise content into it. Script assumes you are in this new folder.
# 2. Merge obsidian readwise content into new vault using this ruby file
# 3. Delete Readwise folder from obsidian vault
# 4. copy the pages files into your obsidian pages folder
# map of url => new filename
