+# Circuitpython as Client
+
+This example demonstrates the use of Socket as a client, accessing a server on a host development machine. This Circuitpython sketch uses the Connect, Send, and Recv_Into methods.
+
+## Prerequisites
+
+Circuitpython V6.2.0 minimum. Neither the host or client sketch has installed module prerequisites.
+
+## Setup
+
+Find a viable IP address for the host machine first and insert it in both sketches as HOST. On mac, this can be done by going to System Preferences/Network and checking the IP address used to connect to the local wireless network. Make sure that both devices are using the same WIFI!
+
+Each sketch can have Timeout values changed. The host sketch usually needs a value above 0, or the recv() will fail. Currently, Circuitpython's Connect function is always blocking, so changing the client timeout will not cause much change in behavior.
+
+Start the Server on the host PC first, within this folder:
+
+```
+python host-server.py
+```
+
+Then, reload the client sketch in Circuitpython.
+
+## Expected Behavior
+
+The example should connect to a server running on the host machine. The client will send a "Hello world" string to the server, which will return it.
+
+Expected client output:
+
+```
+Connecting to wifi
+Creating Socket
+Connecting
+Sending
+Receiving
+bytearray(b'Hello, world')
+```
+
+Expected Server output (IP/port values will vary):
+
+```
+Create Socket
+Accepting connections
+Connected by ('192.168.10.128', 64509)
+got: b'Hello, world'
+sent: b'Hello, world'
+```

+# Circuitpython Datagrams
+
+This example demonstrates using UDP (datagrams) with the Socket module, accessing the time from an NTP server using `sendto` and `recvfrom_into`.
+
+## Prerequisites
+
+Circuitpython V6.2.0 minimum.
+
+## Expected behavior
+
+The Circuitpython device will attempt to connect to wifi, and send a request for the time to `pool.ntp.org`. It will then convert the seconds returned into a unix time struct.
+
+Expected output:
+```
+Sending packet
+Received packet
+Address: ('82.197.188.130', 31488)
+Time: struct_time(tm_year=2021, tm_mon=2, tm_mday=11, tm_hour=22, tm_min=22, tm_sec=40, tm_wday=3, tm_yday=42, tm_isdst=-1)
