-It is advisable to update the [AT firmware](https://www.espressif.com/en/support/download/at?keys=) at least to version
-1.7.0.0
+We advise updating the [AT firmware](https://www.espressif.com/en/support/download/at?keys=) to at least version
+1.7.0.0.
 
-v1.6 driver supports AT firmware up to version 1.6.2. Mbed OS 5.10 supports AT firmwares up to version 1.6.2. v1.7
-driver found from Mbed OS 5.11 allows usage of AT firmware version 1.7.0.0.
+The `v1.6` driver supports AT firmware up to version 1.6.2. Mbed OS 5.10 supports AT firmware up to version 1.6.2. The `v1.7`
+driver found from Mbed OS 5.11 allows you to use AT firmware version 1.7.0.0.
 
-**NOTE** Here we are talking about AT firmware version - not SDK version. SDK firmware without AT is no use.
+**NOTE** This refers to AT firmware version, not SDK version. 
 
-**NOTE** AT firmware version numbers and driver version numbers do not match to each other. E.g., driver version v1.7
-does imply that it will support AT FW version 1.7.0.0
+**NOTE** AT firmware version numbers and driver version numbers do not necessarily correspond: driver version `v1.7`

 ## Restrictions
 
-- The ESP8266 WiFi module does not allow the TCP client to bind on a specific port.
+- The ESP8266 Wi-Fi module does not allow the TCP client to bind on a specific port.
 - Setting up a UDP server is not possible.
-- The serial port does not have hardware flow control enabled by default. The AT command set does not either have a way
-to limit the download rate. Therefore, downloading anything larger than the serial port input buffer is unreliable - 
-unless [AT firmware](https://www.espressif.com/en/support/download/at?keys=) version 1.7.0 or later is used. With older
-firmware an application should be able to read fast enough to stay ahead of the network. This affects mostly the TCP
-protocol where data would be lost with no notification. On UDP - with all firmware versions - this would lead to only
-packet losses which the higher layer protocol should recover from.

 ## Mandatory configuration
-![mbed_lib.json](mbed_lib.json) configuration assumes Arduino form factor. Please adjust according to which board is in
-use. Parameters are overridable from your app config file.
