 ## Status
 
-Work in progress. See the milestones in the project plan; the workspace is
-organized as:
+| Area | Status |
+| --- | --- |
+| CLI (clap, drop-in flags) | done |
+| Configuration (`glances.conf`) | done |
+| Plugin model (limits, views, rates, MMM, history, events, actions) | done |
+| Terminal UI (ratatui) | done |

+| Core plugins | cpu, percpu, mem, memswap, load, fs, network, diskio, sensors, irq, system, uptime, now, core, version, psutilversion, quicklook, processcount, processlist, programlist |
+| Extended plugins | folders, amps, ports, raid, wifi, ip |
+| Not ported yet | containers, vms, gpu/npu/mpp, connections, smart, cloud |
+| Python-specific flags | `--trace-malloc`, `--api-doc`, `--api-restful-doc` rejected with a clear error |
+
+## Build and run
+
+```console
+$ cargo build --release
+$ ./target/release/glances                 # terminal UI
+$ ./target/release/glances --stdout-json cpu,mem,load
+$ ./target/release/glances --fetch
+```
+
+## Differential testing
+
+The `tools/parity.py` script compares the Rust implementation with the Python
+reference implementation (the oracle) plugin by plugin: it runs both for a few
+refreshes and diffs the flattened key sets and value types.
+
+```console
+$ python3 -m venv /tmp/opencode/glances-py
+$ /tmp/opencode/glances-py/bin/pip install /path/to/python-glances
+$ cargo build
+$ python3 tools/parity.py            # all implemented plugins
+$ python3 tools/parity.py cpu mem    # selected plugins
+```
