+## Feature Request (NEW)
+
+You can suggest development of nnfw's features that are not yet available.
+
+The functions requested so far can be checked in the [popular feature request](https://github.sec.samsung.net/STAR/nnfw/issues?utf8=%E2%9C%93&q=is%3Aopen+is%3Aissue+label%3AFEATURE_REQUEST+sort%3Areactions-%2B1-desc) list.
+
+- If the feature you want is on the list, :+1: to the body of the issue. The feature with the most 
+:+1: is placed at the top of the list. When adding new features, we will prioritize them with this reference.
+Of course, it is good to add an additional comment which describes your request in detail.
+
+- For features not listed, [create a new issue](https://github.sec.samsung.net/STAR/nnfw/issues/new).
+Sooner or later, the maintainer will tag the `FEATURE_REQUEST` label and appear on the list.
+
+We expect most current feature requests to be focused on operator kernel implementations.
+It is good to make a request, but it is better if you contribute by yourself. See the following guide, 
+[How to Implement Operator Kernel](docs/HowToImplementOperatorKernel.md), for help.
+
+We are looking forward to your participation.
+Thank you in advance!
