+## Why
+
+When you use karma not in isolation but as part of a build process (e.g. using grunt
+or gulp) it is often the case that the compilation/transpilation is done on a previous
+step of the process and not handled by karma preprocessors. In these cases source maps
+don't get loaded by karma and you lose the advantages of having them.
+
+## How it works
+
+Right now source maps are located via this rule: the preprocessors appends
+".map" to the file name, and if that file exists it loads and includes it.
+
+So if for example you have Hello.js, the preprocessor will try to load source map from
+Hello.js.map.
+
+This is very simple but should work in the majority of cases for standard usage (e.g. with typescript).
