-To open an issue, please keep in mind a few important things. First, take a look at the README docs and make sure that your question isn't already answered in the documentation. In particular, review [the configuration methods](https://github.com/mgonto/restangular#configuring-restangular) and [methods description](https://github.com/mgonto/restangular#methods-description). Then make sure you search the issues list to see if there's already an issue open that solves your problem. Then, once you've determined that your issue isn't a duplicate, here a couple guidelines to opening an issue that will be addressed easily and quickly:
+The project lacks resources to answer questions regarding general usage and problems occurring from misconfiguration and or improper use. That's why we kindly ask you to following the following guidelines when considering opening an issue.
 
-- Please make sure your issue is written in a clear and succint manner, so that all the details of your issue are easy to understand and fully explained. Also, please make sure enclose your code in [fenced blocks](https://help.github.com/articles/creating-and-highlighting-code-blocks/) for readability.
-- Make sure your issue includes a live Plunker (fork [this Plunker](http://plnkr.co/edit/26Heuv5F6hUgxpNWNTee?p=info)), and all relevant code samples (as well as information about server responses, if relevant)
+**Before opening an issue:**
+
+* Please **carefully read the README** and make sure that your question isn't already answered in the documentation.
+* Please **review [the configuration methods](https://github.com/mgonto/restangular#configuring-restangular) and [methods description](https://github.com/mgonto/restangular#methods-description)** once more.
+* Please **search the existing issue list** to see if there's already an issue **open or closed** that solves your problem.
+* Please **search for and/or ask your question on [StackOverflow](http://stackoverflow.com/search?q=restangular)**. You will get answers more quickly there than here.
+* Please **debug your problem long and hard** enough to make sure the issue is in Restangular and not in your code and/or backend.
+
+**When opening an issue:**
+
+* Please **create a live Plunker** (fork [this Plunker](http://plnkr.co/edit/26Heuv5F6hUgxpNWNTee?p=info)) demonstrating the problem, use [httpbin](https://httpbin.org/) or [JSONPlaceholder](https://jsonplaceholder.typicode.com/) or similar as backend if needed.
+* Please **write your issue in a clear and succint manner**, so that all the details of your issue are easy to understand and fully explained.
+* Please **enclose your code in [fenced blocks](https://help.github.com/articles/creating-and-highlighting-code-blocks/)** for readability.
+
+The maintainers may opt to close issues that don't follow these guidelines.
