+# Contributing to php-crud-api
+
+Pull requests are welcome.
+
+## Use phpfmt
+
+Please use "phpfmt" to ensure consistent formatting.
+
+## Run the tests
+
+Before you do a PR, you should ensure any new functionality has test cases and that all existing tests are succeeding.
+
+## Run the build 
+
+Since this project is a single file application, you must ensure that classes are loaded in the correct order. 
+This is only important for the "extends" and "implements" relations. The 'build.php' script appends the classes in 
+alphabetical order (directories first). The path of the class that is extended or implemented (parent) must be above
+the extending or implementing (child) class when listing the contents of the 'src' directory in this order. If you
+get this order wrong you will see the build will fail with a "Class not found" error message. The solution is to
+rename the child class so that it starts with a later letter in the alphabet than the parent class or that you move
+the parent class to a subdirectory (directories are scanned first).
