+# Weather Web-Scraper
+
+An utility to scrape italian weather websites to collect and compare weather
+information
+
+## Usage
+
+> ![CAUTION]  
+> The following utility is in EARLY developement. Many promises made in this
+> readme might not actually be true. Hopefully one day we'll be out of beta ~and
+> be releasing on time~
+
+The scraper collects data and arranges in the following scheme
+
+| Object field | Data Type | Unit of measurement | Meaning |
+| ------------ | --------- | ------------------- | ------- |
+|              |           |                     |         |
+
+> ![WARNING]  
+> The script is configured to run on Nix, and because of this is more
+> complicated than it needs to be. You can remove unnecessary stuff if you're
+> not running this on nix
