+## Introduction
 
 A tag is a local reference to a region of PLC memory.
 Depending on the PLC type and protocol the region may be named.

 ### Data Accessors
 
 Mapping the raw tag buffer to some typed value (e.g. `int`) and vice-versa can be achieved using the built-in [Data Accessor methods](https://github.com/libplctag/libplctag/wiki/API#tag-data-accessors).
-Alternatively, get a copy of the byte array and do the conversion yourself (e.g. with [`BitConverter`](https://learn.microsoft.com/en-us/dotnet/api/system.bitconverter), [`BinaryPrimities`](https://learn.microsoft.com/en-us/dotnet/api/system.buffers.binary.binaryprimitives), [`Encoding`](https://learn.microsoft.com/en-us/dotnet/api/system.text.encoding), among others).

 In general, you will need prior knowedge of the binary format of the tag data, and you may need to reverse-engineer it.
 The manuals provided by your device manufacturer are the best source of information on these details.
