Maybe just add something like "You can also get a daily updated geany.pot from https://i18n.geany.org/geany.pot" on https://www.geany.org/Contribute/Translators.
When i translate other software i find it easier to just get one file. The pot file.
From that i can start a new translation.
When i want to update the translation later on i just get a new pot file and use that to update. With "msgmerge --update" or from inside a GUI program where it can be done from the menu in some tools like Virtaal.
