Updating a config file for a plugin

[A Former User]

Hello,

I am creating a plugin on QGIS. I have 2 interfaces : in the first one, the user must select three entries to launch the second interface. As I want to save the three entries in a config file that would be loaded when launching the plugin, so that the user doesn't select the entries. I tried to create this file and to write in it but I have problems when updating one entry for example. My config file is very simple : one line for each entry, I have three lines.

I want to have some ideas, a sample of how developing a config file for a plugin on QGIS.

Thanks for your help.
