* Add more description on unspecified directory
In the example code, the "js" folder appeared for the first time and there is no clue where the current folder is. Therefore, there should be some comments describing what the folder is. Otherwise, like me, spent a lot of time guessing what codes - some release version or the source code - should be downloaded to go to the "js" directory.
* Add detailed description on how to run js tests
The test files are directly in the Protocol Buffer project js folder. Add more detailed instruction on how and where to run the tests.
* Correct two spelling mistakes
The two spelling mistakes mentioned in your comments are corrected.
Add some supporting documentation regarding Closure for those unfamiliar., Also substantiate details for "files in this directory" - including them all will result in a project that does not compile as some are used for test cases and aren't part of the core library.
