+## Code Review for TextProcessing Repository
+The purpose of this pull request is to perform a code review of the TextProcessing Repository.  The program reads a text file, removes punctuation, makes all the words lowercase, counts occurrences of each word, and writes the unique words in alphabetical order. 
+The review covers documentation, error handling, and seven key areas, with suggestions to improve clarity, usability, and robustness.
+
+1. Is the Code Properly Documented/Commented?
+The code includes some helpful comments (like "Read all lines" and "Dictionary to hold word counts"), but documentation is limited and could be more comprehensive.
+
+Needs Work?: 
+Yes, several adjustments are needed.
+
+Suggestions:
+- A summary comment at the beginning of the Main method to clearly explain what the program accomplishes. 
+- Comments for complex functionality, like the regex string pattern used to clean the text.
+
+2. Does the Code Handle Errors Properly?
+The code includes basic error handling by checking if the file exists with File, but there is no well-thought-out or meaningful error handling.
+
+Needs Work?: 
+Yes, moderate improvement is needed.
+
+Suggestions:
+- Use a try-catch block for File.ReadAllLines to handle exceptions like IOException.
+- Check if Console.ReadLine() input is null or empty.
+- Handle empty or unreadable files gracefully.
+
+3. Suggestions for Improvement
+Naming:
+Variable names like wordCounts, filePath, lines, cleanedLine, and words are descriptive, which is good. However, pair in the output loop is generic and could be more specific.
+Suggestion: Rename pair to wordEntry for clarity in the output loop.
+
+Code Structure:
+All logic is in the Main method, with no separation into reusable functions, making the code less modular and harder to maintain or test.
+Suggestion: Break it into methods like ReadFile(), CleanLine(), CountWords(), DisplayResults().
+
+Error Handling:
+Only checks if the file exists.
+suggestion: Add try-catch for full error handling for file reading and invalid inputs.
+
+File Assumptions:
+Assumes the user enters a valid file path after the existence check. No default file (e.g., sample.txt) is provided, which could improve usability.
+Suggestion: Use a default file like sample.txt 
+
+OOP Principles:
+The code is procedural, with no classes or encapsulation, limiting reusability and modularity.
+Suggestion: May Create a WordCounter class to encapsulate the dictionary and processing logic, with methods for reading, cleaning, counting, and displaying.
+
+Output:
+Clear and sorted alphabetically.
+
+Program Logic:
+Logic is efficient and correct. But for large files, use File.ReadLines instead of File.ReadAllLines to save memory.
