You import it and create an "instance" the same way you would with the class `FastAPI`:

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../docs_src/bigger_applications/app/routers/users.py!}
```

### *Path operations* with `APIRouter` { #path-operations-with-apirouter }

And then you use it to declare your *path operations*.

Use it the same way you would use the `FastAPI` class:

     * silently {@link #addNode(Object) add} {@code nodeU} and {@code nodeV} to the graph.
     *
     * @return this {@code Builder} object
     * @throws IllegalArgumentException if the introduction of the edge would violate {@link
     *     #allowsSelfLoops()}
     */
    @CanIgnoreReturnValue
    public ImmutableValueGraph.Builder<N, V> putEdgeValue(N nodeU, N nodeV, V value) {

{* ../../docs_src/metadata/tutorial001.py hl[3:16, 19:32] *}

You can write Markdown in the `description` field and it will be rendered in the output.

With this configuration, the automatic API docs would look like:

## License identifier { #license-identifier }

            File file = null;
            try {
                file = new File(new URI(filePath));
            } catch (final URISyntaxException e) {
                logger.warn("Could not parse url: " + filePath, e);
            }

            if (file == null) {
                responseData.setHttpStatusCode(Constants.NOT_FOUND_STATUS_CODE);
                responseData.setCharSet(charset);

## Use `StaticFiles` { #use-staticfiles }

* Import `StaticFiles`.
* "Mount" a `StaticFiles()` instance in a specific path.

{* ../../docs_src/static_files/tutorial001.py hl[2,6] *}

/// note | Technical Details

You could also use `from starlette.staticfiles import StaticFiles`.

**FastAPI** provides the same `starlette.staticfiles` as `fastapi.staticfiles` just as a convenience for you, the developer. But it actually comes directly from Starlette.

And then you can set the `status_code` in that *temporal* response object.

{* ../../docs_src/response_change_status_code/tutorial001.py hl[1,9,12] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

            resultData.setRawData(generateData(responseData));
            resultData.setSerializer(dataSerializer::fromObjectToBinary);
        } catch (final Exception e) {
            throw new CrawlingAccessException("Could not serialize object", e);
        }
        resultData.setEncoding(fessConfig.getCrawlerCrawlingDataEncoding());

        return resultData;
    }

    /**
     * Generate the data.

        try {
            searchEngineClient.deleteByQuery(fessConfig.getIndexDocumentUpdateIndex(), queryBuilder);

        } catch (final Exception e) {
            logger.error("Could not delete expired documents: {}", queryBuilder, e);
            resultBuf.append(e.getMessage()).append("\n");
        }

        return resultBuf.toString();
    }
