 A web scraping project that extracts fight and fighter data from [ufcstats.com](http://ufcstats.com), transforms it into structured wide-format tables, and enriches it with historical performance statistics. 
 
+The UFC (Ultimate Fighting Championship) is a premier mixed martial arts (MMA) promotion showcasing elite-level fighters across multiple weight classes.
+
 ## Project Overview
 
 This tool performs the following:
 
-- Scrapes data from `ufcstats.com` including:
+- Scrapes **all available** data from `ufcstats.com` including:
   - Fighter profiles (name, height, reach, stance, etc.)
   - Fight outcomes and statistics (strikes, takedowns, control time, etc.)
   - Event information (event title, date, winner)
-- Transforms the raw data into a clean wide-format table:
+- Transforms the raw data into a clean wide-format table, where:
   - Each row represents **one fight**
   - Contains data for **both fighters** in separate columns
 - Computes **cumulative performance metrics** for each fighter across fights to enable longitudinal analysis
-
-## Output Example
+- Converts units from U.S. customary to metric system (e.g., inches to centimeters, pounds to kilograms) to support European-format data handling
+
+Note: The original dataset does not include cumulative or historical statistics for each fighter prior to a given fight (e.g., total significant strikes, takedowns, or submission attempts). To enable performance analysis, these metrics are calculated separately based on each fighter’s fight history up to that point. However, to keep the dataset compact, these intermediate cumulative values are not stored in the final output—only the derived pre-fight performance metrics are retained.
+Data was last extracted on March 10, 2025.
+
+## Libraries Used
+- Data Consolidation: argparse, json, os, re
+- Web Scraping: BeautifulSoup, requests, time
+- Data Analysis & Transformation: pandas, numpy, math
+
+## Workflow
+1. Scrape web data from [ufcstats.com] using custom scripts.
+2. Cache all raw HTML and JSON files locally for reproducibility and offline access 
+3. Transform scraped data into structured format:
+   - Flatten nested data
+   - Convert units (from U.S. customary to EU metric system)
+4. Compute the following historical performance statistics by calculating cumulative strikes, takedowns, opponent's strikes and defence, etc per fighter before each fight.
+   - Significant Strikes Absorbed per Minute (SApM)
+   - Average Takedowns Landed per 15 Minutes (TD Avg.)
+   - Significant Strikes Landed per Minute (SLpM)
+   - Average Submissions Landed per 15 Minutes (Sub. Avg.)
+   - Significant Striking Accuracy (Str. Acc.) 
+   - Takedown Accuracy (TD Acc.)
+   - Takedown Defense (TD Def.)
+   - Significant Strike Defense (Str. Def.)
