+Command line HTML parser/scraper used for grabbing torrents from [ThePirateBay](https://thepiratebay.se). Downloads torrents using command line program, transmission-daemon.
 
 Initially made for the older version with torrents hosted from a separate subdomain, but now modified for grabbing magnet links instead.

+## Requirements
+
+This script was written in Python version 2.7. Version 3 compatibility requires rewriting some code, and may be done at a later time. Pull requests welcome.
+
+This script depends on 3 external Python libraries. Please ensure the following are installed to the system:
+
+ * transmissionrpc
+ * requests
+ * beautifulsoup4
+
+If pip is installed, just run:
+
+```
+pip install transmissionrpc requests beautifulsoup4
+```
+
 ## Usage
 
 Place the script somewhere in your executable path. I like ~/bin
 
 ```
 $ mkdir ~/bin
-$ echo 'PATH=$PATH:~/bin' > .bashrc
+$ echo 'PATH=$PATH:~/bin' >> ~/.bashrc && source ~/.bashrc
+$ cp pirate/pirate.py ~/bin
 ```
 
 Then just run it
