+## Troubleshooting
+
+Common issues and solutions when developing GitButler.
+
+### Turbo/build issues
+
+#### Case-sensitive volume problems
+
+If you're experiencing issues with the `dev:desktop` target failing to start, especially on macOS with case-sensitive filesystems, this may be related to Turborepo's handling of case-sensitive volumes.
+
+**Solution:** See the related issue at [vercel/turborepo#8491](https://github.com/vercel/turborepo/issues/8491) for current workarounds.
+
+#### Turbo daemon issues
+
+If builds are hanging or behaving unexpectedly:
+
+```bash
+# Stop the turbo daemon
+pnpm exec turbo daemon stop
+
+# Clear turbo cache
+pnpm exec turbo daemon clean
+
+# Restart development
+pnpm dev:desktop
+```
+
+### Cache issues
+
+If you're seeing stale builds or unexpected behavior:
+
+```bash
+rm -rf .turbo node_modules
+pnpm install
+# Optional (Rust artifacts):
+cargo clean
+```
+
+### Node.js & pnpm
+
+Use the Node version pinned by `.nvmrc` (currently LTS “jod” / Node 22):
+
+```bash
+nvm install
+nvm use
+node -v
+```
+
+Use pnpm via Corepack (avoid global installs):
+
+```bash
+corepack enable
+corepack pnpm -v
+# optionally pin a major:
+corepack prepare pnpm@10 --activate
+```
