 ### Installation
 
+#### Update Site
+
 An alpha version of our tool is available via an Eclipse update site at: https://raw.githubusercontent.com/ponder-lab/Optimize-Java-8-Streams-Refactoring/master/edu.cuny.hunter.streamrefactoring.updatesite. Please choose the latest version of the "Optimize Stream Refactoring."
 
 #### Dependencies
 
-The refactoring has several dependencies whose update sites do not seem to always resolve correctly in Eclipse. If you experience any trouble installing the plug-in using the above update site, you can manually install the dependencies using the list of update sites below. The latest version of each plug-in should be installed in the order they are presented:

 Dependency | Update Site

 [WALA](https://github.com/ponder-lab/WALA) | https://raw.githubusercontent.com/ponder-lab/WALA/master/com.ibm.wala.updatesite
 [SAFE](https://github.com/ponder-lab/safe) | https://raw.githubusercontent.com/ponder-lab/safe/master/com.ibm.safe.updatesite

+##### WALA
+
+Please note that there is a special dependency on WALA. Currently, our refactoring requires **WALA version 1.3.10**. Although this version from the official WALA site would theoretically work, the plug-in has been tested with the WALA version whose update site is listed above. We highly recommend that this version of WALA be used with the plug-in, which may require uninstalling other WALA features from your current Eclipse installation. [Issue #192](https://github.com/ponder-lab/Optimize-Java-8-Streams-Refactoring/issues/192) has been opened to track the future integration.

 ### Marking Entry Points
 
 Explicit entry points may be marked using the appropriate annotation found in the corresponding [annotation library][annotations]. They can also be marked using a text file named `entry_points.txt`. The processing of this file is recursive; it will search for this file in the same directory as the source code and will traverse up the directory structure until one is found. As such, the file may be placed in, for example, package directories, subproject directories, and project roots. The format of the file is simply a list of method signatures on each line.
