+# Wordcloud Images for Wikipedia Article
+Python script that prompts the user for an input, searches for the corresponding article on wikipedia and generates a wordcloud based on the searched article.
+
+### Prerequisites
+`pip install` the models in `requirements.txt` from your command prompt.
+
+### How to run the script
+Run like any other python file. Upon executing, the wordcloud image will be saved to the current directory. The script will also prompt a y/n if the user wants to see the generated image during execution.
