| # Perfetto UI |
| |
| ## Quick Start |
| |
| ```bash |
| $ git clone https://android.googlesource.com/platform/external/perfetto/ |
| $ cd perfetto |
| |
| # Will build into ./out/ui by default. Can be changed with --out path/ |
| # The final bundle will be available at ./ui/out/dist/. |
| # The build script creates a symlink from ./ui/out to $OUT_PATH/ui/. |
| ui/build |
| |
| # This will automatically build the UI. There is no need to manually run |
| # ui/build before running ui/run-dev-server. |
| ui/run-dev-server |
| ``` |
| |
| Then navigate to `http://localhost:10000`. |
