 ## Files to change
 
 There are currently two files which need to be edited:
 
 1. [`src/json.hpp`](https://github.com/nlohmann/json/blob/master/src/json.hpp)
 
-2. [`test/src/unit.cpp`](https://github.com/nlohmann/json/blob/master/test/unit.cpp) - This contains the [Catch](https://github.com/philsquared/Catch) unit tests which currently cover [100 %](https://coveralls.io/github/nlohmann/json) of the library's code.
+2. [`test/src/unit-*.cpp`](https://github.com/nlohmann/json/tree/develop/test/src) - These files contain the [Catch](https://github.com/philsquared/Catch) unit tests which currently cover [100 %](https://coveralls.io/github/nlohmann/json) of the library's code.
 
    If you add or change a feature, please also add a unit test to this file. The unit tests can be compiled and executed with
 
    ```sh
-   make check
+   $ mkdir build
+   $ cd build
+   $ cmake ..
+   $ cmake --build .
+   $ ctest
    ```
 
    The test cases are also executed with several different compilers on [Travis](https://travis-ci.org/nlohmann/json) once you open a pull request.

.github/ISSUE_TEMPLATE.md

+**Bug Report**
+
+- What is the issue you have?
+
+- Please describe the steps to reproduce the issue. Can you provide a small but working code example?
+
+- What is the expected behavior?
+
+- And what is the actual behavior instead?
+
+- Which compiler and operating system are you using? Is it a [supported compiler](https://github.com/nlohmann/json#supported-compilers)?
+
+- Did you use a released version of the library or the version from the `develop` branch?
+
+- If you experience a compilation error: can you [compile and run the unit tests](https://github.com/nlohmann/json#execute-unit-tests)?
+
+
+**Feature Request**
+
+- Describe the feature in as much detail as possible.
+
+- Include sample usage where appropriate.

-## Note
-
-- If you open a pull request, the code will be automatically tested with [Valgrind](http://valgrind.org)'s Memcheck tool to detect memory leaks. Please be aware that the execution with Valgrind _may_ in rare cases yield different behavior than running the code directly. This can result in failing unit tests which run successfully without Valgrind.
+- [ ]  Changes are described in the pull request, or an [existing issue is referenced](https://github.com/nlohmann/json/issues).
+- [ ]  The test suite [compiles and runs](https://github.com/nlohmann/json/blob/develop/README.md#execute-unit-tests) without error.
+- [ ]  [Code coverage](https://coveralls.io/github/nlohmann/json) is 100%. Test cases can be added by editing the [test suite](https://github.com/nlohmann/json/tree/develop/test/src).
