To use Jasmine with a simple project, download the standalone distribution for the desired version of Jasmine from this list. Edit the SpecRunner.html file (located in the root of your jasmine standalone download):
add your source files as separate <script> tags before the Jasmine files to the head element
add your spec files as separate <script> tags after the Jasmine files to the head element
All paths pointing to lib/jasmine-jasmine-1.1.0.rc1, if any, should point to the parent directory. E.g.: lib/jasmine-1.1.0.rc1/jasmine.js should point to ../jasmine.js
Point your favorite browser to the SpecRunner.html file and reload to run your specs.
As you add new files to your project, make sure to add source and spec <script> tags.
