+# Aiohttp Server support [aiohttp-server-support]
+
+Getting Elastic APM set up for your Aiohttp Server project is easy, and there are various ways you can tweak it to fit to your needs.
+
+
+## Installation [aiohttp-server-installation]
+
+Install the Elastic APM agent using pip:
+
+```bash
+$ pip install elastic-apm
+```
+
+or add `elastic-apm` to your project’s `requirements.txt` file.
+
+
+## Setup [aiohttp-server-setup]
+
+To set up the agent, you need to initialize it with appropriate settings.
+
+The settings are configured either via environment variables, the application’s settings, or as initialization arguments.
+
+You can find a list of all available settings in the [Configuration](/reference/configuration.md) page.
+
+To initialize the agent for your application using environment variables:
+
+```python
+from aiohttp import web
+
+from elasticapm.contrib.aiohttp import ElasticAPM
+
+app = web.Application()
+
+apm = ElasticAPM(app)
+```
+
+To configure the agent using `ELASTIC_APM` in your application’s settings:
+
+```python
+from aiohttp import web
+
+from elasticapm.contrib.aiohttp import ElasticAPM
+
+app = web.Application()
+
+app['ELASTIC_APM'] = {
+    'SERVICE_NAME': '<SERVICE-NAME>',
+    'SECRET_TOKEN': '<SECRET-TOKEN>',
+}
+apm = ElasticAPM(app)
+```
+
+
+## Usage [aiohttp-server-usage]
+
+Once you have configured the agent, it will automatically track transactions and capture uncaught exceptions within aiohttp.
+
+Capture an arbitrary exception by calling [`capture_exception`](/reference/api-reference.md#client-api-capture-exception):
+
+```python
+try:
+    1 / 0
+except ZeroDivisionError:
+    apm.client.capture_exception()
+```
+
+Log a generic message with [`capture_message`](/reference/api-reference.md#client-api-capture-message):
+
+```python
+apm.client.capture_message('hello, world!')
+```
+
+
+## Performance metrics [aiohttp-server-performance-metrics]
+
+If you’ve followed the instructions above, the agent has already installed our middleware. This will measure response times, as well as detailed performance data for all supported technologies.
+
+::::{note}
+due to the fact that `asyncio` drivers are usually separate from their synchronous counterparts, specific instrumentation is needed for all drivers. The support for asynchronous drivers is currently quite limited.
+::::
+
+
+
+### Ignoring specific routes [aiohttp-server-ignoring-specific-views]
+
+You can use the [`TRANSACTIONS_IGNORE_PATTERNS`](/reference/configuration.md#config-transactions-ignore-patterns) configuration option to ignore specific routes. The list given should be a list of regular expressions which are matched against the transaction name:
+
+```python
+app['ELASTIC_APM'] = {
+    # ...
+    'TRANSACTIONS_IGNORE_PATTERNS': ['^OPTIONS ', '/api/']
+    # ...
+}
+```
+
+This would ignore any requests using the `OPTIONS` method and any requests containing `/api/`.
+
+
+## Supported aiohttp and Python versions [supported-aiohttp-and-python-versions]
+
+A list of supported [aiohttp](/reference/supported-technologies.md#supported-aiohttp) and [Python](/reference/supported-technologies.md#supported-python) versions can be found on our [Supported Technologies](/reference/supported-technologies.md) page.
+
+::::{note}
+Elastic APM only supports `asyncio` when using Python 3.7+
