 ## qutil.matlab
 In this module there are functions that are helpful for reading `.mat` files, especially those created with special measure. If you simply want to open a random `.mat` file you can use `hdf5storage.loadmat`.
 
+## qutil.const
+This module defines all the constants you could wish for as well as functions to convert temperatures (`convert_temperature`) or between wavelengths and frequencies (`lambda2nu`, `nu2lambda`). For an overview, see the module docstring.
+
 ## qutil.linalg
 This module provides several handy linear algebra functions. While some are implemented elsewhere, the implementation here is typically speedier for large arrays. For example, `pauli_expm` exploits the fact that a matrix exponential of Pauli matrices can be written as a cosine times the identity matrix plus a sine times the Paulis to speed up the calculation. 
 
 For an overview of the included functions, see the module docstring.
 
+## qutil.ui
+This module collects UI helpers, such as a progress bar for loops that can be used like so:
+```python
+for i in qutil.ui.progressbar(range(n)):
+    do_something()
+```
+
 ## qutil.qi
 In this module there are some quantities and functions related to quantum information, like the Pauli matrices in different data types.
