 this library offers a streamlined and powerful way to add reflection capabilities to your C++ enums and other types. We've optimized the core functionality,
 focusing on the main features developers usually want. We've also added general purpose typename reflection for any type.

 # 2. Introduction
@@ -66,14 +68,12 @@ Based on the awesome work in [`magic_enum`](https://github.com/Neargye/magic_enu
 this library offers a streamlined and powerful way to add reflection capabilities to your C++ enums and other types. We've optimized the core functionality,
 focusing on the main features developers usually want. We've also added general purpose typename reflection for any type.
 
-For the latest cutting edge changes, see the [dev branch](https://github.com/fix8mt/conjure_enum/tree/dev).

 ## b) Embracing C++20
 
 `conjure_enum`[^1] takes full advantage of recently added C++20 features. We've leveraged the convenience of [`std::source_location`](https://en.cppreference.com/w/cpp/utility/source_location) and
 unlocked the potential of [`constexpr` algorithms](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0202r3.html) and [concepts](https://en.cppreference.com/w/cpp/language/constraints).

 - ***Modern C++20***: Entirely `constexpr` for compile-time safety, efficiency and performance; no macros

+You can specialise this class to override the defaults and set your own flags on a per enum basis:

+shows a reduction in overall compile times.
+
+### iii. `FIX8_CONJURE_ENUM_SET_FLAGS`
+For convenience, this macro is provided to make it easier to set custom flags. This macro takes an enum typename followed by two `bool` values indicating
+the values of `is_continuous` and `no_anon`.

 This library provides a workaround (hack :smirk:) to current limitations of C++. There are proposals out there for future versions of the language that will provide proper reflection.

 This library provides a workaround (hack :smirk:) to current limitations of C++. There are proposals out there for future versions of the language that will provide proper reflection.

-# 6. Building
+# 6. API for `fixed_string`
+`fixed_string` is a specialisation of `std::array` that provides statics storage for an ASCII zero (asciiz) string. The purpose of this class is to allow the
+creation of `constexpr` strings with specfic storage, adding a trailing `0`. It is used by `conjure_enum` to store all strings. API is described below. Other uses of this class are possible.
+
+## a) Creating a `fixed_string`
+```c++
+template<std::size_t N>
+class fixed_string;
+constexpr fixed_string(std::string_view sv);
+```
+Constructs a `fixed_string` from a `std::string_view`. Note the size must be passed as a template paramater.
+```c++
+std::string_view sv{"The rain in Spain"};
+fixed_string<sv.size()> fs{sv};
+```
+
+## b) `get`
+```c++
+constexpr std::string_view get() const;
+```
+Returns the strings as a `std::string_view`;
+
+## c) `c_str`
+```c++
+constexpr const char *c_str() const;
+```
+Returns the strings as a null terminated `const char *`.
+
+## d) `c_str`
+```c++
+constexpr operator std::string_view() const;
+```
+Provides a `std::string_view` cast.
+
+## e) `c_str`
+```c++
+constexpr char operator[](size_t idx) const;
+```
+
+## f) `size`
+```c++
+constexpr std::size_t size() const;
+```
+Returns the size of the `fixed_string` including the null terminator.
+
+## g) `std::ostream& operator<<`
+```c++
+std::ostream& operator<<(std::ostream& os, const fixed_string& what)
+```
+Provides an `ostream` insertor.
+

 # 4. API and Examples using `enum_bitset`
 `enum_bitset` is a convenient way of creating bitsets based on `std::bitset`. It uses your enum (scoped or unscoped)
 for the bit positions (and names).
-> [!WARNING]
+> [!NOTE]
 > - Your enum sequence _must_ be 0 based
 > - Continuous
 > - The last value must be less than the count of enumerations
 > - This implementation is limited to 64 bits
 >
-> We decided on this restriction for both simplicity and practicality - bitsets only really make sense when represented in this manner.

 `fixed_string` is a specialisation of `std::array` that provides statics storage for an ASCII zero (asciiz) string. The purpose of this class is to allow the
 creation of `constexpr` strings with specfic storage, adding a trailing `0`. It is used by `conjure_enum` to store all strings. API is described below. Other uses of this class are possible.

-With a given enum, search and call user supplied invocable. Use this method where complex event handling is required, allowing you to easily declare predefined invocable actions
+With a given enum, search and call user supplied invocable. A typical use case would be where you want to demux a complex event, allowing you to easily declare predefined invocable actions
 for different enum values.
 
-Where invocable returns a value, return this value or a user supplied "not found" value.
-Where invocable is void, call user supplied "not found" invocable.
+- Where invocable returns a value, return this value or a user supplied "not found" value.
+- Where invocable is void, call user supplied "not found" invocable.
+
 The first parameter of your invocable must accept an enum value (passed by `dispatch`).
 Optionally provide any additional parameters. Works with lambdas, member functions, functions etc.
 
 There are two versions of `dispatch` - the first takes an enum value, a 'not found' value, and a `std::array` of `std::tuple` of enum and invocable.
 The second version takes an enum value, and a `std::array` of `std::tuple` of enum and invocable. The last element of the array is called if the enum is not found.
 This version is intended for use with `void` return invocables.
+
 The second version of each of the above is intended to be used when using a member function - the _first_ parameter passed after your array must be the `this` pointer of the object.
 You can also use `std::bind` to bind the this pointer and any parameter placeholders when declaring your array.
 If you wish to pass a `reference` parameter, you must wrap it in `std::ref`.
