There is no need to re-download https://codeberg.org/susam/wander every few weeks. The setup is a one-time step. From that repository, you copy exactly two files (index.html and wander.js) and place them on your web server, preferably within a /wander/ directory. After that, you only maintain the wander.js file.

You curate your own links and choose which other Wander consoles to link to as neighbours. The contents of wander.js are entirely yours to define. There is no need to diff or compare it with the version in the repository.

In fact, if you do not care about updating or curating links over time, you can leave both files untouched indefinitely. The only downside is that some links may eventually succumb to link rot, which could affect the wandering experience. So it may help to review your links occasionally and remove dead ones, but beyond that no ongoing maintenance is required.
