 ## Troubleshooting
 
-If the installer cannot be found, run from the repository root or set `EQL_INSTALLER`.
+If the pinned installer hash fails, Daybreak probably replaced the installer. Update the `fetchurl` hash in `packages/eqlegends/package.nix`, or temporarily set `EQL_INSTALLER`.

+The launcher may emit repeated `libEGL warning` lines while CEF probes graphics paths under Wine. The wrapper filters those by default. To see the raw output:

+```bash
+EQL_FILTER_EGL_WARNINGS=0 nix run .#eqlegends
