 ```sh
-$ ./hb-unicode-encode 41 42 43 627 | ./record-test.sh ../../util/hb-shape font.ttf >> tests/test-name.test

 ```
 
 If you created a new test file, add it to `Makefile.am` so it is run.
 Check that `make check` does indeed run it, and that the test passes.
 When everything looks good, `git add` the new font as well as new
 test file if you created any.  You can see what new files are there
-by running `git status tests fonts/sha1sum`.  And commit!
+by running `git status data/in-house`.  And commit!
 
 *Note!*  Please only add tests using Open Source fonts, preferably under
 OFL or similar license.
