 Under the `psr-0` key you define a mapping from namespaces to paths, relative to the
 package root. Note that this also supports the PEAR-style non-namespaced convention.
 
+Please note namespace declarations should end in `\\` to make sure the autoloader
+responds exactly. For example `Foo` would match in `FooBar` so the trailing
+backslashes solve the problem: `Foo\\` and `FooBar\\` are distinct.
+
 The PSR-0 references are all combined, during install/update, into a single key => value
 array which may be found in the generated file `vendor/composer/autoload_namespaces.php`.
