+#Scrape test module
+
+The scrape test module is intended to test the immplementation of the library at scale by parsing a large amount of webpages and checking the quality of its results
+
+## Data
+
+At this moment
+
+* one dataset was found on [Kaggle](https://www.kaggle.com/datasets/hetulmehta/website-classification).
+* another on [Moz](https://moz.com/top-500/download/?table=top500Domains) (Top 500 most visited websites).
+
+I'd like a more varied set of data from different types of sources, and the current set mostly seem to contain homepages but it's surprisingly hard to find.
+
+## Running the tests
+
+For various reasons, I am not uploading the actual data of the various URLs. To run the analysis yourself:
+
+1. Run `Scraper.kt` once, which will grab all the webpages and place them in the `data/web` folder.
+2. Run `ParserTest.kt`, which will run the `Parser` on each of those web pages and check whether the tags can be extracted, and if the page is considered valid.
