+## Reviewers guide
+
+When reviewing pull request there are common things a reviewer should keep
+in mind.
+
+Reviewing changes to `src/*` and `nuklear.h`:
+
+* Ensure C89 compatibility.
+* The code should work for several backends to an acceptable degree.
+* Recommend simple optimizations.
+  * Pass small structs by value instead of by pointer.
+  * Use local buffers over heap allocation when possible.
+* Check that the coding style is consistent with code around it.
+  * Variable/function name casing.
+  * Indentation.
+  * Curly bracket (`{}`) placement.
+* Ensure that the contributer have bumped the appropriate version in
+  [package.json](https://github.com/Immediate-Mode-UI/Nuklear/blob/master/package.json)
+  and added their changes to the
+  [CHANGELOG](https://github.com/Immediate-Mode-UI/Nuklear/blob/master/src/CHANGELOG).
+* Have at least one other person review the changes before merging.
+
+Reviewing changes to `demo/*`, `example/*` and other files in the repo:
+
+* Focus on getting working code merged.
+  * We want to make it easy for people to get started with Nuklear, and any
+    `demo` and `example` improvements helps in this regard.
+* Use of newer C features, or even other languages is not discouraged.
+  * If another language is used, ensure that the build process is easy to figure out.
+* Messy or less efficient code can be merged so long as these outliers are pointed out
+  and easy to find.
+* Version shouldn't be bumped for these changes.
+* Changes that improves code to be more inline with `nuklear.h` are ofc always welcome.
