+## Testing a DevContainer Feature
+
+To test a particular devcontainer feature, say, `lazygit`:
+
+```bash
+devcontainer features test -f lazygit -i mcr.microsoft.com/devcontainers/base:ubuntu-24.04 .
+```
+
+- `--skip-scenarios` ... tests only the `test.sh` test case, but no scenario tests.
+- `--filter alpine --skip-autogenerated` ... tests only the `alpine` scenario
+  (and neither `test.sh`).
+
+## Installing/Upgrading the DevContainer CLI
+
+```bash
+npm install -g @devcontainers/cli@latest
+```
