     $ pip install 'hg+https://hg.adblockplus.org/codingtools#egg=patchconv&subdirectory=patchconv'
 
 ## Usage
 
 The script in the package will be available immediately after the installation.
 Its interface is simple: it reads from stdin and writes to stdout.
 
-    $ patchconv <patch-from-rietveld.diff >git-patch.diff
+    $ cat patch-from-rietveld.diff | patchconv >git-patch.diff
 
-For additional convenience you can use the provided `rapply.sh` script that
-downloads, converts and applies patches from Rietveld reviews to your local
-working copy. In order to use it, open a review, copy the URL of a `[raw]`
-download link in the top right corner of a patch set overview and then paste it
-into the console:
+You can also download the patch directly from the review and apply it directly
+without saving to a file:
+
+    $ curl https://.../issue3322_4433.diff | patchconv | git apply
+
+This is a common sequence of commands so we have a script that automates it,
+for both Mercurial and Git (it autodetects the VCS). In order to use it, open a
+review, copy the URL of a `[raw]` download link in the top right corner of a
+patch set overview and then paste it into the console:
 
     $ rapply.sh https://codereview.adblockplus.org/download/issue3322_4433.diff
 
-or, if you've already downloaded the diff to a local file:
+or, if you have already downloaded the diff to a local file:
 
     $ rapply.sh issue3322_4433.diff
 
 In both cases you need to be in the directory containing the repository to
 which you are applying the diff.
