-Charge equilibration method for crystal structures
+Charge equilibration method for crystal structures.
+
+# NOTE
+The EQeq charge equilibration algorithm is now included as a feature in the
+[openbabel](http://openbabel.org/wiki/Main_Page) project, enabling its use with
+over 100 chemical file formats across multiple programming languages. As such,
+this version of the algorithm is no longer in development - please switch to
+openbabel.
+
+To run EQeq from openbabel, use these sample code snippets as a starting point:
+
+```python
+# Python
+import pybel
+mol = pybel.readfile("cif", "filename.cif")
+pybel.ob.OBChargeModel_FindType("eqeq").ComputeCharges(mol.OBMol)
+partial_charges = [atom.partialcharge for atom in mol]
+```
+
+```c++
+// C++
+OBMol inputMolecule;
+OBChargeModel *eqeqCharges = OBChargeModel::FindType("eqeq");
+eqeqCharges->ComputeCharges(inputMolecule);
+vector<double> partialCharges = eqeqCharges->GetPartialCharges();
+```
+
+Other languages, file types, and charge models are also supported - read the
+openbabel docs for more.
+
