+-------------------------------
+To add test cases in any suite:
+-------------------------------
+
+  1) If the test requires dialyzer to analyze a single file place it in the
+     suite's 'src' directory. If analysis of more files is needed place them
+     all in a new directory in suite's 'src' directory.
+
+  2) Create a file with the same name as the test (if single file, omit the
+     extension else directory name) containing the expected result in suite's
+     'result' directory.
+
+  3) Run './remake <suite>', where <suite> is the suite's name omitting 
+     "_tests_SUITE".
+
+----------------------
+To create a new suite:
+----------------------
+
+  1) Create a directory with the suffix 'tests_SUITE_data'. The name should 
+     describe the suite.
+
+  2) In the suite's directory create subdirectories 'src' and 'results' as
+     well as a 'dialyzer_options' file with the following content:
+
+        {dialyzer_options, List}.
+        {time_limit, Limit}.
+
+        where:
+
+        List  = a list of dialyzer options. Common case will be something
+                like [{warnings, Warnings}], where Warnings is a list of valid
+                '-W' prefixed dialyzer options without the 'W' prefix (e.g.
+                '-Wfoo' would be declared as [{warnings, [foo]}].
+        Limit = the amount of time each test case is allowed to run. Must be
+                bigger than the time it takes the most time-consuming test to
+                finish.
+     
+     Any of these lines may be missing. Default options list is empty and
+     default time limit is 1 minute.
+
+  3) Add tests as described in previous section.
+
+  4) Add the resulting suite's name in the Makefile's MODULES variable.
