 <h4> Tree-sitter Queries </h4>
 
-The Tree-sitter queries language is one of the rule languages that Piranha supports. 
 For a detailed understanding of the syntax, refer to the [Tree-sitter Syntax Reference](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries).
 
 <h4> Regular Expressions (Regex) </h4>
 
-Regex forms another rule language supported by Piranha. To create a rule in regex, prepend your query with `rgx `. 
+To create a rule in regex, prepend your query with `rgx `.
 For instance: `rgx <your regex query>`. Piranha supports the regex syntax derived from the [regex](https://docs.rs/regex/) crate.
 
 <h4> Concrete Syntax </h4>
 
-Piranha's Concrete Syntax is a custom rule language designed for matching and replacing code. Concrete Syntax operates at the parse tree level, similar to [comby](https://comby.dev/).
+Piranha's Concrete Syntax is a custom rule language designed for matching and replacing code. 
+Concrete Syntax operates at the parse tree level, similar to [comby](https://comby.dev/).
 The key difference is that it matches a parse tree node only if the entire parse tree can be traversed using the concrete syntax template.
 
-To use concrete syntax, prepend the query with `cs <your_query>`. For example, to match the code snippet `exp.isTreated("SHOW_MENU")`, you can use the following query `cs :[object].isTreated(:[string])`
