13-28: LGTM! Clear and comprehensive BFS documentation.The BFS section is well-structured with clear explanations of parameters and outputs.
29-75: Well-documented PageRank implementation!The PageRank documentation is comprehensive and technically accurate, covering all essential aspects including usage, parameters, outputs, and important considerations. The examples and explanations are clear and helpful.

13-28: Consider adding a code example for BFS.The BFS documentation would benefit from a practical example, similar to the one provided in the PageRank section. This would help users understand how to use the algorithm in practice.
Would you like me to provide a sample code example for the BFS usage?
42-54: Fix markdown formatting issues.Please address the following markdown formatting issues:
- Add language specification to the code fence (e.g., ```cypher)
- Use consistent code block style for parameters (prefer fenced over indented)
-``` +```cypher CALL algo.pageRank( 'NodeLabel', // The label of the nodes to include in the computation 'RELATIONSHIP_TYPE' // The type of relationships to consider ) YIELD nodeId, score
