+### Void Linux (XBPS)
+
+Void x86_64 with glibc and runit is the native target. Its XBPS channel is
+withheld until the host-acceptance gate passes; do not install proof artifacts
+from it. Once a Fenris Release lists XBPS as available, add the permanent
+signed repository, refresh its metadata, and install the package:
+
+```bash
+sudo install -d -m 0755 /etc/xbps.d
+echo 'repository=https://git.bongbetic.com/xavierk/Fenris-xbps/raw/branch/stable/x86_64' \
+  | sudo tee /etc/xbps.d/fenris.conf
+sudo xbps-install -S fenris
+```
+
+XBPS requires remote repositories to be signed. On the first refresh it
+displays the repository signing key embedded in the signed metadata; accept it
+only when its RSA SHA256 fingerprint is
+`SHA256:AvPMRlKMikPg75u0iKr8AUkxlfU/Ad4k/S4o2M9W4/w`. The public key is also
+available at
+`https://git.bongbetic.com/xavierk/Fenris-xbps/raw/branch/stable/keys/fenris-xbps-signing.pub`.
+For later updates, always refresh first so XBPS fetches the current index:
+
+```bash
+sudo xbps-install -Syu
+```
+
+The runit service remains dormant after installation. `fenris monitor resume`
+creates `/var/service/fenris-collect`; pause removes that link and records a
+deliberate disable in the observation history.
+
+Fenris keeps the observation store root-written and readable by the `fenris`
+group. Add each TUI user to that group, then start a new login session before
+running Fenris:
+
+```bash
+sudo usermod -aG fenris "$USER"
+```

 No interval key exists in `/etc/fenris/fenris.conf`. Cadence is a systemd concern, not a Fenris configuration key.
 
+On Void, Fenris uses its native runit service instead: its initial collection
+is delayed by two minutes and later collections run five minutes after the
+previous run finishes. Inspect its state and diagnostics with:
+
+```bash
+sv status fenris-collect
+sudo tail -n 50 /var/log/fenris-collect/current
