+# How a Person is tracked in this Logseq knowledge garden
+This is an extension to logseq-flavored-markdown `logseq-flavored-markdown.mdc` for recording information about a person.
+
+A person entry is a logseq page where the page title matches one of the following patterns:
+- [[People/Full Name]] (corresponds to `pages/People___Full Name.md`)
+- [[Person/Full Name]] (corresponds to `pages/Person___Full Name.md`)
+- [[<AnyNamespace>/People/Full Name]] (e.g., `pages/HU___People___Full Name.md`)
+- [[<AnyNamespace>/Person/Full Name]] (e.g., `pages/AI___Person___Full Name.md`)
+
+### When to Create a Person Page
+
+Person pages should only be created for individuals who meet one or more of these criteria:
+- Known across multiple platforms (e.g., GitHub, Twitter, Stack Overflow)
+- Have a confirmed real identity
+- Are significant contributors or maintainers
+- Have a substantial online presence
+- Are key figures in their field
+
+For other users, use site-specific namespaces:
+- `[[CursorAI/Forum/User/Username]]` for Cursor Forum users
+- `[[Reddit/User/Username]]` for Reddit users
+- `[[StackOverflow/User/Username]]` for Stack Overflow users
+- `[[ForumName/User/Username]]` for other forum users
+
+### Creating a Person Page
+
+If you are asked to make an entry for a person, you should:
+
+1. **Search First**
+   - Search in `pages/People___*.md`, `pages/Person___*.md`, and in any file matching `pages/**___People___*.md` or `pages/**___Person___*.md` to find if a person already exists
+   - If it already exists, then you should **update** the existing entry
+   - A single person should not have more than one person page
+
+2. **Verify Significance**
+   - Confirm the person meets the criteria for a person page
+   - If not, use the appropriate site-specific namespace instead
+
+3. **Create/Update Page**
+   - If a new person page is needed, create it under `[[Person/Full Name]]` by default
+   - If the person is referenced in other contexts/namespaces (e.g., `[[People/Full Name]]`, `[[HU/Person/Full Name]]`), add aliases in the frontmatter to those contexts using `alias::` (not `aliases::`)
+   - Look up the person on the internet
+   - Create a person page for them if they meet the criteria
+   - Link the person and a bit of their bio in their page
+   - If possible add an image link
+   - Include relevant external links (GitHub, LinkedIn, etc.)
+
+4. **Journal Entry**
+   - If the person page is new, make an entry in today's journal page that links to that person
