 In an effort to streamline the browsing experience for text only, gophermap rendering will not include lines with gophertypes that are not 0, 1, or i (text/display elements). Stubb supports bookmarks, file save, and session only history (cleared on quit). 
 
-Support for search is currently under consideration. I have not generally found Gopher search to be particularly useful. The lack of tagging and organization makes most search results from Veronica2 seem like playing the lottery. We'll see.
+Search has been implemented with a default of Veronica2 as the search service.

 ### Setup
 
-Make sure your system has Lua 5.1 on it. I believe this application should work with 5.2 (so long as you get the appropriate dependencies), however, I believe the socket library is buggy for 5.3, so best to stay on an earlier version.
+Stubb has been tested with Lua versions >= 5.1. I had been told that the socket library is buggy on 5.3, but have not experienced any problems myself. Most testing has been done with 5.1 and 5.2. 
 
-If you do not have luarocks package manager, get it and run: `luarocks install luasocket`
+Luasocket is required. It can be acquired via luarocks with: `luarocks install luasocket`. You can also get it via [github](https://github.com/diegonehab/luasocket). Using luarocks is recommended as the easier option.
 
 That should take care of dependencies. You just need to make sure that __stubb__ (found in this repo) is executable and you are good to go.

 ### Versions
 
-This repo contains two files: `stubb` and `stubb-lite`. The later has a simpler menu structure and lacks support for having multiple tabs open. The filesize and memory usage should be similar, but the navigation may involve fewer keypresses in the lite version.
