+Upgrade instructions:
+=====================
+
+
+0.4.x -> 0.5.0:
+===============
+
+There were some major changes since 0.4.x.
+
+First enter the LAM configuration editor and check if all settings are correct. Since
+LAM now supports a plugin architecture for all accounts you can select the needed
+modules. Click on "Edit modules" and select which account types you want to manage.
+Depending on which modules you selected there might be more configuration options.
+
+Now save your settings and login to LAM. You will have to recreate all your account
+profiles because the format changed. The profile editor can be found on the tools
+page ("Tools" in the upper left corner).
+
+The tools page also includes the new flexible file upload and the PDF editor.
+You can specify yourself which attributes should show up in the PDF files. There
+are also different PDF profiles possible.
