+### Copy/paste not working on Linux
+
+Linux users need to have one of the following clipboard utilities installed for copy/paste functionality to work:
+
+**For X11 systems:**
+
+```bash
+apt install -y xclip
+# or
+apt install -y xsel
+```
+
+**For Wayland systems:**
+
+```bash
+apt install -y wl-clipboard
+```
+
+**For headless environments:**
+
+```bash
+apt install -y xvfb
+# and run:
+Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 &
+export DISPLAY=:99.0
+```
+
+opencode will automatically detect and use the first available clipboard tool in order of preference: `xclip`, `xsel`, then `wl-clipboard`.
