+When creating new pull requests, please consider the following.
+
+* Read the Contributing guide linked above first.
+* If you are adding a new linter, remember to update the README.md file and
+  doc/ale.txt first.
+* If you add or modify a function for converting error lines into loclist items
+  that ALE can work with, please add Vader tests for them. Look at existing
+  tests in the test/handler directory, etc.
+* If you add or modify a function for computing a command line string for
+  running a command, please add Vader tests for that.
+* Generally try and cover anything with Vader tests, although some things just
+  can't be tested with Vader, or at least they can be hard to test. Consider
+  breaking up your code so that some parts can be tested, and generally open up
+  a discussion about it.
+* Have fun!
