-## Usage

 ## Installation
 
 Using `pip`:
 
 ```sh
 pip install clamdpy
 ```
+
+## Usage
+
+```python
+from io import BytesIO
+
+from clamdpy import ClamdNetworkSocket
+
+clamd = ClamdNetworkSocket(
+    host="127.0.0.1",
+    port=3310,
+    timeout=15,
+)
+
+clamd.ping()
+#> 'PONG'
+
+clamd.version()
+#> VersionInfo(version='ClamAV 0.103.9', signature=27065, signature_date=datetime(2023, 10, 18, 9, 49, 14))
+
+# Raw response can be fetched as well:
+clamd.version(raw=True)
+#> 'ClamAV 0.103.9/27065/Wed Oct 18 09:49:14 2023'
+
+clamd.instream(BytesIO(b"data"))
+#> ScanResult(path='stream', reason=None, status='OK')
+```
+
+Most of the [clamd commands](https://github.com/Cisco-Talos/clamav/blob/main/docs/man/clamd.8.in) are implemented (a couple ones are missing and should be implemented sooner or later).
+
+It is possible to use [UNIX sockets](https://docs.python.org/3/library/socket.html#socket.AF_UNIX) as well:
+
+```python
+from clamdpy import ClamdUnixSocket
+
+clamd = ClamdUnixSocket(path="/var/run/clamav/clamd.ctl")
+```
+
+### Line delimitations
+
+By default, `\n` will be used to terminate lines. Clamd also supports `NULL` characters:
+
+```python
+from clamdpy import ClamdNetworkSocket
+
+clamd = ClamdNetworkSocket(line_terminator="z")
+```
+
+> [!WARNING]\
+> Support for the `NULL` character isn't tested and may not work as it doesn't play well with Python. Use with caution.
