 # Linux Sublime Dev
 
 Sublime Text is a fast, powerful and easily extensible code editor. Check out
 some [visual demos](http://www.sublimetext.com) for a quick demonstration.
 
 You can download and install Sublime Text 3 from the [Sublime Text
 Website](http://www.sublimetext.com/3). Assuming you have access to the right
 repositories, you can also install Sublime via apt-get on Linux. Help and
 general documentation is available in the [Sublime Text 3
 Docs](http://www.sublimetext.com/docs/3/).

 ## CodeSearch Integration with Chromium X-Refs
 
 With [Chromium X-Refs](https://github.com/karlinjf/ChromiumXRefs/) you can
-perform [https://cs.chromium.org](https://cs.chromium.org] cross-reference
+perform [https://cs.chromium.org](https://cs.chromium.org) cross-reference
 searches in your editor. This gives you the call graph, overrides, references,
 declaration, and definition of most of the code. The results are as fresh as
 the search engine's index so uncomitted changes won't be reflected.
 
 More information on Chromium X-Ref's functionality (including keyboard and
 mouse shortcuts) can be found on the [Chromium X-Refs
 page](https://github.com/karlinjf/ChromiumXRefs/).
