+#+STARTUP: showeverything
+
+* Set up CI on Travis
+* Write tests
+
+* malloc/free : Parameters for accelerators?
+We should define qmckl_malloc and qmckl_free just to give the
+possibility of the HPC implementations to define how they allocate the
+memory (on CPU or GPU, using alternatives to malloc/free, etc).
+A possibility could be to pass the id of a NUMA domain as a parameter of
+qmckl_malloc, where the domain id is something obtained from the
+context.

+
+* Verificarlo TODO
+These are installation instructions for
+verificarlo which needs to be moved to 
+an appropriate place at some point.
+** Compilation and Testing
+
+The following steps were required to get
+the verificarlo version up and running on
+an Ubuntu 20.04 laptop.
+
+1. Compilers
+   a. clang - For e.g. clang-7
+   b. flang - For e.g. flang-7 : Care needs to be taken
+                                 that the flang version 
+                                 is compatible with the
+                                 clang version used.
+                                 There are known issues
+                                 with using oneAPI due
+                                 to flang being incompatible
+                                 with oneAPI supplied clang.
+   c. gcc   - For e.g. gcc-7
+
+2. Environment varibales
+   a. VFC_BACKENDS - For e.g. `VFC_BACKENDS="libinterflop_ieee.so"`
