+# Arista EOS API asyncio Client
+
+This repository contains an Arista EOS asyncio client.
+
+### Quick Example
+
+Thie following shows how to create a Device instance and run a list of
+commands.
+
+Device will use HTTPS transport by default.  The Device instance supports the
+following initialization parameters:
+
+   * `host` - The device hostname or IP address
+   * `username` - The login username
+   * `password` - The login password
+   * `proto` - *(Optional)* Choose either "https" or "http", defaults to "https"
+   * `port` - *(Optional)* Chose the protocol port to override proto default
+
+The Device class inherits directly from httpx.AsyncClient.  As such, the Caller
+can provide any initialization parameters.  The above specific parameters are
+all optional.
+
+```python
+import json
+from aioeapi import Device
+
+username = 'dummy-user'
+password = 'dummy-password'
+
+async def run_test(host):
+    dev = Device(host=host, username=username, password=password)
+    res = await dev.cli(commands=['show hostname', 'show version'])
+    json.dumps(res)
+```
+
+### References
+
+Arista eAPI documents require an Arista Portal customer login.  Once logged into the
+system you can find the documents in the Software Download area.  Select an EOS release
+and then select the Docs folder.
