+# Entity Guidance
+
+`entity` is the type for concrete things: projects, systems, tools, technologies or people.
+Entities are the primary building blocks of the knowledge graph.
+
+## When to use
+
+- Representing a software project, an initiative or a piece of work
+- Documenting a running system, service or infrastructure component
+- Describing a CLI tool, utility or software library
+- Recording information about a language, a framework or a protocol
+- Documenting a person, a team or an organization
+
+## When NOT to use
+
+- For abstract concepts, patterns or methodologies (use `concept`)
+- For source documents or ingested material (use `source`)
+- For comparative analyses (use `comparison`)
+
+## Authoring guidance
+
+- The title is the entity's canonical name and follows the subject's established designation, not the KB language (`kb/CONTRACT.md` § "Titles are identifiers", `kb/CONVENTIONS.md` §§ "Naming" and "Language")
+- The main description goes near the top
+- Link to related entities and concepts wherever relationships exist
+- Under `provenance: sourced` or `mixed`, back hard facts inline with a `[^cite-id]` footnote -
+  `tools/wikitool cite add --page "<Title>" --source "Source - X"` mints the id and its definition
+- Wikipedia register: factual, neutral, no marketing language
+
+---
+
+Relevant Notes:
+
+- Entity pages form the concrete inventory of the knowledge base
+- Every entity type (project, system, tool and so on) is a variant of this base type
+- The relationships between entities carry the knowledge graph's interconnection
