 ## Install (Fedora)
 
+Uses the shared `lair-cafe` dnf repo (same repo/GPG key as the other `lair`
+packages). If you've already configured `lair-cafe.repo` on a host, just
+`sudo dnf install claude-desktop`. Otherwise:
+
 ```bash
-sudo tee /etc/yum.repos.d/lair.repo <<'EOF'
-[lair]
-name=lair
-baseurl=https://rpm.lair.cafe/fedora/$releasever/x86_64/
+sudo rpm --import https://rpm.lair.cafe/8b2023ce.gpg
+sudo tee /etc/yum.repos.d/lair-cafe.repo > /dev/null <<'EOF'
+[lair-cafe]
+name=lair.cafe RPM Repository
+baseurl=https://rpm.lair.cafe/fedora/$releasever/$basearch/
 enabled=1
 gpgcheck=1
-gpgkey=https://rpm.lair.cafe/RPM-GPG-KEY-lair
+gpgkey=https://rpm.lair.cafe/8b2023ce.gpg
 EOF
 sudo dnf install claude-desktop
 ```
 
-(Use the same `.repo`/GPG-key convention as the other `lair` packages if one
-already exists on your hosts.)
+Subsequent `dnf upgrade` picks up new Claude Desktop versions automatically.
+
+## Runtime notes
+
+If Chromium's sandbox misbehaves on a host with restricted user namespaces:
+`claude-desktop --no-sandbox`, or `sudo sysctl kernel.unprivileged_userns_clone=1`.
