 - You can track a term by simply putting it in the box.
 - You can track a set of terms by simply putting terms in an array surrounded by the '\' character. You can also set a custom threshold regarding the number of terms that must match to trigger the detection. For example, if you want to track the terms _term1_ and _term2_ at the same time, you can use the following rule: `\[term1, term2, [100]]\`
 - You can track regexes as easily as tracking a term. You just have to put your regex in the box surrounded by the '/' character. For example, if you want to track the regex matching all email address having the domain _domain.net_, you can use the following aggressive rule: `/*.domain.net/`.

+Crawler
+---------------------
+In AIL, you can crawl hidden services.
+
+two types of configutation [explaination for what]:
+	1) use local Splash dockers (use the same host for Splash servers and AIL)
+	2) use remote Splash servers
+
+- (Splash host) Launch ``crawler_hidden_services_install.sh`` to install all requirement (type ``y`` if a localhost splah server is used)
+- (Splash host) Setup your tor proxy[is already installed]: 
+	- Add the following line in ``/etc/tor/torrc: SOCKSPolicy accept 172.17.0.0/16``
+  	  (for a linux docker, the localhost IP is 172.17.0.1; Should be adapted for other platform)
+	- Restart the tor proxy: ``sudo service tor restart``
+
+- (Splash host) Launch all Splash servers with: ``sudo ./bin/torcrawler/launch_splash_crawler.sh [-f <config absolute_path>] [-p <port_start>] [-n <number_of_splash>]``
+  all the Splash dockers are launched inside the ``Docker_Splash`` screen. You can use ``sudo screen -r Docker_Splash`` to connect to the screen session and check all Splash servers status.
+
+- (AIL host) Edit the ``/bin/packages/config.cfg`` file:
+	- In the crawler section, set ``activate_crawler`` to ``True``
+	- Change the IP address of Splash servers if needed (remote only)
+	- Set ``splash_onion_port`` according to your Splash servers port numbers who are using the tor proxy. those ports numbers should be described as a single port (ex: 8050) or a port range (ex: 8050-8052 for 8050,8051,8052 ports).
+
+- (AIL host) launch all AIL crawler scripts using: ``./bin/LAUNCH.sh -c``
