+
+### Adapter Warnings
+If listen is having trouble with the underlying adapter, it will display warnings with `Kernel#warn` by default,
+which in turn writes to STDERR.
+Sometimes this is not desirable, for example in an environment where STDERR is ignored.
+For these reasons, the behavior can be configured using `Listen.adapter_warn_behavior =`:
+``` ruby
+Listen.adapter_warn_behavior = :warn   # default (true means the same)
+Listen.adapter_warn_behavior = :log    # send to logger.warn
+Listen.adapter_warn_behavior = :silent # suppress all adapter warnings (nil or false mean the same)
+```
+Also there are some cases where specific warnings are not helpful.
+For example, if you are using the polling adapter--and expect to--you can suppress the warning about it
+by providing a callable object like a lambda or proc that determines the behavior based on the `message`:
+``` ruby
+Listen.adapter_warn_behavior = ->(message) do
+  case message
+  when /Listen will be polling for changes/
+    :silent
+  when /directory is already being watched/
+    :log
+  else
+    :warn
+  end
+end
+```
+In cases where the `Listen` gem is embedded inside another service--such as `guard`--the above configuration
+can be set in the environment variable `LISTEN_GEM_ADAPTER_WARN_BEHAVIOR=warn|log|silent`.
+
 ## Listen Adapters
 
 The `Listen` gem has a set of adapters to notify it when there are changes.
