+### Credentials
+
+It is recommended to install a libsecret compliant keyring application, such as [GNOME Keyring](https://wiki.gnome.org/action/show/Projects/GnomeKeyring) (aka seahorse). This will allow saving your password securely between launches.
+
+In GNOME, things should work out of the box. It might be a bit trickier to get it working in other DEs: see this [ArchWiki entry](https://wiki.archlinux.org/index.php/GNOME/Keyring) for detailed explanations on how to automatically start the daemon with your session.
+
+Bear special attention to the fact that to enable automatic login, you might have to use the same password for your user account and for the keyring, and that the keyring might need to be [set as default](https://wiki.archlinux.org/index.php/GNOME/Keyring#Passwords_are_not_remembered).
+
+See [this comment](https://github.com/xou816/spot/issues/92#issuecomment-801852593) for more details!
+
+
+### Settings
 
 Spot can also be configured via `gsettings` if you want to change the audio backend, the song bitrate, etc.

+## Contributing
+
+Contributions are welcome!
+
+### Translating
+
+Translations are managed using `gettext` and are available in the `po/` subdirectory.
+
+To contribute translations:
+- fork the repository;
+- copy the `po/spot.pot` file and rename it to match your language code, or edit the relevant `po` file if it already exists;
+- if needed, add your language code to `po/LINGUAS`;
+- make sur the `Language` and `Plural-Forms` keys are correct;
+- edit the `msgstr` entries.
+
+Note that nice tools exist to help you work with `po` files ([Poedit](https://poedit.net/) for instance).
+
+If you can't build Spot locally, you may run the `spot-snapshots` action against your branch from your Github fork (...I think?) to obtain a flatpak debug build.

 ## Building

 ### Manually

 ### Regenerating potfiles
 
+When adding new `msgids`, don't forget to regenerate/update the potfiles.

 ```
 ninja spot-pot -C target
 ninja spot-update-po -C target
 ```
 
 ### Debugging
 
+Debug builds (flatpak) are available from the master branch on Github (see the `spot-snaphots` action).

+Spot caches images and HTTP responses in `~/.cache/spot`.

 Spot uses [isahc](https://github.com/sagebind/isahc), which uses libcurl, therefore you can set the `https_proxy` env variable to help with debugging. In debug mode, Spot skips SSL certificate verification.
