+The first two guides will explain the basic concepts of Cypher query syntax, including how to create and query data.
 Cypher is based on ASCII art, so the syntax is easily understood and makes queries more self-explanatory.
 It focuses on the clarity of expressing what to retrieve from a graph, not on how to retrieve it.
 
 We will discuss the keywords for each CRUD operation and how to specify nodes, relationships, and properties in the query language.
 Learning how to specify patterns and filter data results will allow you to traverse the graph or add and remove data.

+Many query languages include the capability to run subqueries inside outer queries, and Cypher offers this, as well.
+There are a couple of different approaches to syntax, depending on the type of subquery needed.
+
+We can use existential subqueries to filter more complex scenarios like patterns and even entire nested queries for more accurate and focused results.
+We can also use result-returning subqueries to sort and order filtered results.
+While organizing filtered results was previously possible in Cypher, providing subquery support allows us to simplify the syntax and avoid using APOC procedures or additional Cypher clauses to pass and sort values along the way.
