 ## Rework solver
 
-* Split solve in solve_coord, solve_generic (and maybe solve_singlethread, see
-  notes about build options).
-* Add a void * extradata to DfsArg.
+### Architecture
+
+* Nail down the theory first
+* One generic solve module that does not depend on anything else,
+  not even on cube if possible
+* The generic file includes the logic for branching and calls functions
+  provided as parameters to move the cube and check the status etc...
+* This includes the logic for single/multithreading (simplify if compiled
+  with N_THREADS = 1 or whatever this option is going to be)
+* The data representing the cube is a void pointer
+* Move two-step solve to a different module
+* Each other solver (solve coord, solve fst, solve multistep)
+  should go in a separate module
+
+### Other practicalities
+
 * remove cube from dfsarg? (i still need to save the scramble somewhere,
   but I really only use it in dfs_niss)
 * Re-work prepare_step process for solve_generic (nxopt table is special).
