-== Cypher Manual: intended readership
-
-The Cypher Manual aims to be as instructive as possible to readers from a variety of backgrounds and professions, such as developers, administrators, and academic researchers. 
-In so doing, it assumes a degree of prior knowledge of Cypher.
-
-The Cypher Manual is, therefore, not primarily intended for beginners (in other words, readers who have never used Cypher before).
-Beginners are instead encouraged to visit the link:{neo4j-docs-base-uri}/getting-started/{page-version}/cypher-intro/[Cypher Getting Started Guide], and enroll in the free Cypher courses offered by https://graphacademy.neo4j.com/[Neo4j GraphAcademy].
