 CORRECTNESS
 -----------
 
     * libsoup builds with lots of -W options by default, and should
-      not print any warnings while compiling (unless they're caused by
-      #included files from other projects, eg, proxy.h). You can use
-      "make > /dev/null" to do a full compile showing only the
-      warnings/errors, to make sure your patch does not introduce any
-      more.
+      not print any warnings while compiling.
 
     * There are a number of regression tests in the tests/ directory.
-      Running "make check" will run all of them (or at least, all of
+      Running "ninja test" will run all of them (or at least, all of
       the ones that it can run based on what software you have
       installed. Eg, some tests require apache to be installed.) You
-      should run "make check" before submitting a patch that could
-      potentially change libsoup's behavior. ("make check" will warn
-      you if it was not able to run all of the tests. If you are
+      should run "ninja test" before submitting a patch that could
+      potentially change libsoup's behavior. If you are
       making extensive changes, or changing very low-level functions,
       you may want to install all of the optional pieces so you can
       run all of the regression tests.)
-
-    * libsoup ought to build correctly from outside its source tree,
-      so if you make large changes to the Makefiles, try a "make
-      distcheck" to verify that an out-of-source-tree build still
-      works.
