+\section SupportedCompilers Supported compilers
+
+As of PLUMED 2.4, we require a compiler that supports C++11. The following compilers
+(or later versions) should be sufficient:
+
+- gcc 4.8.1
+- clang 3.3
+- intel 15
+
+Notice that the `./configure` script verifies that your compiler supports C++11.
+Some compilers do not declare full support, but implement anyway a number of C++11 features
+sufficient to compile PLUMED (this is the case for instance of intel 15 compiler).
+In case you see a warning about C++11 support during `./configure`
+please make sure that PLUMED compiles correctly and, if possible, execute the regtests
+(using `make regtest`). Notice that we regularily test a number of compilers on travis-ci,
+and at least those compilers are guaranteed to be able to compile PLUMED correctly.
