+## MR 174 : Fix online payment + allow users to pay their subscription
+
+Add the possibility to use custom payment methods. There is also a boolean field on the 
+Payments allowing every user to use some kinds of payment. You have to add the rights `cotisations.use_every_payment` and `cotisations.buy_every_article`
+to the staff members so they can use every type of payment to buy anything.
+
+Don't forget to run migrations, several settings previously in the `preferences` app ar now
+in their own Payment models.
+
+To have a closer look on how the payments works, pleas go to the wiki.
