 By far better: the test points us to two files we for sure need to include in <code>MANIFEST</code> and precisely: <code>MANIFEST.SKIP</code> and <code>t/01-validate.t</code>
 
-Go to the <code>MANIFEST</code> file and add them (where they are appropriate, near similar files and paying attention to case an paths), then commit the change. If you rerun the above test you'll see files added to <code>MANIFEST</code> are no more present in the failure output.
+Use the <code>make manifest</code> command to add them automatically, then commit the change. If you rerun the above test you'll see files added to <code>MANIFEST</code> are no more present in the failure output.
 
 Let's examine the remaining two files. What is <code>ignore.txt</code>? It was created as default ignore list by <code>module-starter</code> and it contains many lines of regexes. If we want <code>module-starter</code> to create <code>MANIFEST.SKIP</code> instead, next time we'll use it specify <code>--ignores='manifest'</code> For the moment we can delete it. Commit.
