 We’d love you to help us improve this project. To help us keep this collection
 high quality, we request that contributions adhere to the following guidelines.
+Any contributions that don't meet these guidelines will be closed.
 
 - **Provide a link to the application or project’s homepage**. Unless it’s
   extremely popular, there’s a chance the maintainers don’t know about or use
   the language, framework, editor, app, or project your change applies to.
 
+- **Provide a reason for making this change**. Even if it seems self-evident,

+  happen. It’s especially helpful to articulate why this change applies to
+  *everyone* who works with the applicable technology, rather than just you or
+  your team.
+
 - **Provide links to documentation** supporting the change you’re making.
   Current, canonical documentation mentioning the files being ignored is best.

-- **Please consider the scope of your change**. If your change specific to a
-  certain language or framework, then make sure the change is made to the

+- **No duplicate rules**. It's easy to do, but it creates confusion and
+  introduces the risk of one or the other being missed in an update.

 In general, the more you can do to help us understand the change you’re making,
 the more likely we’ll be to accept your contribution quickly.
 
 If a template is mostly a list of files installed by a particular version of
 some software (e.g. a PHP framework) then it's brittle and probably no more
 helpful than a simple `ls`. If it's not possible to curate a small set of
-useful rules, then the template might not be a good fit for this collection.
+useful rules, then the template is not a good fit for this collection.
 
 Please also understand that we can’t list every tool that ever existed.
