+# Experimental APIs
+
+Some of Electrons APIs are tagged with `_Experimental_` in the documentation.
+This tag indicates that the API may not be considered stable and the API may
+be removed or modified more frequently than other APIs with less warning.
+
+## Conditions for an API to be tagged as Experimental
+
+Anyone can request an API be tagged as experimental in a feature PR, disagreements
+on the experimental nature of a feature can be discussed in the API WG if they
+can't be resolved in the PR.
+
+## Process for removing the Experimental tag
+
+Once an API has been stable and in at least two major stable release lines it
+can be nominated to have its experimental tag removed.  This discussion should
+happen at an API WG meeting.  Things to consider when discussing / nominating:
+
+* The above "two major stables release lines" condition must have been met
+* During that time no major bugs / issues should have been caused by the adoption of this feature
+* The API is stable enough and hasn't been heavily impacted by Chromium upgrades
+* Is anyone using the API?
+* Is the API fulfilling the original proposed usecases, does it have any gaps?
