-*irprinter* is a small commandline-based tool developed to explore LLVM IR code.
-The tool can print IR code of only specific functions, when dumping of the whole translation unit would produce too much output.
+*irprinter* is a command-line tool for exploring LLVM Intermediate Representation (IR) code. 
+It allows users to print IR code for specific functions, which is particularly useful when dumping the entire translation unit would result in excessive output.
 
 
-## Main features
-Print LLVM IR code of a translation unit (C/C++) to a console.
-  - Ability to modify and add compiler flags (e.g., replace `-g` with `-O2`) and re-generate the (modified) IR
-  - Regex matching of (demangled) function names, with the ability to print
-      1) Function signatures only, and,
-      2) Functions including body
-  - Dump whole IR code of the TU
