 Its main use case is to provide an interface to annotate code regions.
 These annotated regions then can be used with multiple backends to gain insight in application behavior.
 
-## Bindings
-
-To make neSmiK easily usable, we provide Fortran, C, C++ bindings to the library.
-
-### CXX bindings
-
-```cpp
-#include "nesmik/nesmik.hpp"
-
-int main() {
-  nesmik::Init("ProperlyNested","Default"); // inits the nesmik library
-  nesmik::RegionStart("peter");
-
-    nesmik::RegionStart("marie");
-
-    nesmik::RegionStop("marie");
-
-  nesmik::RegionStop("peter");
-  nesmik::Finalize();
-}
-```
-
-### Fortran
-
-To enable the Fortran module to be built please add `-DBUILD_C_FORTRAN=ON` to the cmake flags.
-
-```fortran
-program test
-    use nesmik_mod
-    call Init("ProperlyNested","Default")
-    call RegionStart("test")
-    call RegionStop("test")
-    call Finalize()
-  end program test
-```
-
-Please consider having a look into the documentation (which will be available soon) for further details.

-| ProperlyNested    | Extrae::TypeStack | Extrae backend using different Types for the levels of nesting |
-| ProperlyNested    | TALP::Tree        | DLB-TALP backend printing a tree to visualize the nesting      |
-| NotProperlyNested | TALP              | DLB-TALP backend to register the monitoring regions            |
