+## Overview
+
+This is a simple web scraper for [chess.com](https://www.chess.com/coaches)
+coaches. Running:
+```bash
+$> python3 main.py
+```
+will query [chess.com](https://www.chess.com) for all listed coaches as well as
+specific information about each of them (their profile, recent activity, and
+stats). The result will be found in a newly created `data` directory with the
+following structure:
+```
+data
+├── coach
+│   ├── <member_name>
+│   │   ├── <member_name>.html
+│   │   ├── activity.json
+│   │   └── stats.json
+│   ├── ...
+└── pages
+    ├── <n>.txt
+    ├── ...
+```
+
+Here, `member_name` corresponds to the name of the coach whereas `pages`
+contains a fragmented list of URLs to coach profiles.
