 These examples show how to do a real-time tddft calculation.
-One can set 'calculation' to be 'md' and esolver_type to be 'tddft' to do TDDFT calculation.
+One can set 'calculation' to be 'md' and 'esolver_type' to be 'tddft' to do TDDFT calculation.
 
 A time-dependent E-field can be applied by setting 'td_vext' to '1'.
-- For Non-periodic system, you could set 'stype' to '0' to do length gauge calculation, which would be faster.
-- For Periodic system, you could set 'stype' to '1' to do velocity gauge calculation.
-velocity gague has not been fully tested yet, so be careful about its results.
