 # CONTRIBUTING TO FACETS
 
 * Facets methods must have no external dependencies. (The only possible
-  exception to this is fi we decide to spin functor methods off to a
-  separate functor gem, but for now that is not happening.)
+  exception to this is if the functor gets spun-off as a separate gem along
+  with related methods, but for now that's not happening.)
+
+* Each method must be in it's own file of the same name. If the method ends
+  with `=` or `?` just leave it off the file name. On rare occasion two or more
+  methods can be very tightly related. In these cases he methods can all go in
+  a single file under the name of the method considered most significant. 
+  Files for the other methods should usually still be create that simply
+  require the main file.
 
 * Methods must be tested either via a Lemon unit test or a QED demo,
-  preferrably both. The Lemon unit tests are for testing a method in
+  preferably both. The Lemon unit tests are for testing a method in
   detail whereas the QED demos are for demonstrating usage.
 
 * Facets is divided into two parts, *core* and *standard* libraries.

 * Some core methods are included on a *trial* basis, and these are not 
   necessary loaded automatically with `require 'facets'`.
 
+* Standard libraries that are not extensions of existing standard libraries
+  do not have to be divvied up into individual method files. But note that
+  full classes and/or modules are less likely to make it into Facets, as
+  these sorts of additions to Facets are only for very basic sorts of things.
+  Otherwise they'd deserve their own gem.
+
+* When submitting new methods for consideration, it is best if each method
+  (or tightly related set of methods) is in it's own pull request. This can be
+  done either through separate commits or separate branches. Let me emphasizes
+  this point because it makes it *much more likely* that your pull request
+  will be merged. If you submit a bunch of methods in a single request, it is
+  more likely that the request will not be merged even if methods you submitted
+  are accepted!!!
+
+* Don't be discouraged when you get feedback about a method that isn't
+  all sunshine and roses. Facets has been around long enough now that 
+  it needs to maintain a reasonable level of quality, and that means
+  serious discernment about what goes into the library. That includes 
+  discussion about the best name for a method --even if the functionality
+  has been accepted the name may not.
