+### Ox String Types
+
+Ox has six different major string types.
+These types are divided into two categories: store types and view types.
+
+String stores maintain a copy of the string data, whereas view types only
+maintain a reference to the data.
+Views should be used where you otherwise might use a const reference to a
+string store type.
+
+Having all of these different string types may sound like an interoperability
+nightmare, but taking string view types extensively where applicable makes the
+imagined interoperability issues virtually non-existent.
+
+#### String Store Types
+
+##### String / BasicString
+
+```ox::String```, or really ```ox::BasicString```, is Ox's version of
+```std::string```.
+Like ```std::string```, ```String``` allocates to store the string data.
+Also like ```std::string```, ```String``` allows for small string
+optimization for strings under 8 bytes.
+Unlike ```std::string```, the template that ```String``` is based on,
+```BasicString```, takes a parameter that allows adjusting to different size
+small string buffers.
+```ox::String``` is an alias to ```ox::BasicString<8>```.
+
+```cpp
+// s can hold up to 100 bytes, plus one for a null terminator before allocating
+ox::BasicString<100> s;
+```
+Also unlike ```std::string```, ```ox::String``` has an explicit C-string conversion
+constructor.
+This prevents accidental instantiations of ```String```.
+
+Consider the following:
+
+```cpp
+void fStd(std::string const&);
+void fOx(ox::String const&);
+
+int main() {
+    // implicit and silent instantiation of std::string, which includes an
+    // allocation
+    fStd("123456789");
+    // Will fail to compile:
+    fOx("123456789");
+    // But explicit String instantiation will work:
+    fOx(ox::String{"123456789"});
+}
+```
+
+##### IString
+
+```IString```, or "inline string", is like ```BasicString```, but it will cut
+off strings that exceed that limit.
+
+```cpp
+ox::IString<5> s; // s can hold up to 5 characters, plus a null terminator
+s = "12345";      // valid
+s = "123456";     // will compile and run, but will get cut off at '5'
+```
+
+This is useful for certain string categories that have fixed lengths, like UUID
+strings or for numbers.
+
+Ox makes use of ```IString``` in the following ways:
+
+```cpp
+using UUIDStr = ox::IString<36>;
+
+// and
+
+template<Integer_c Integer>
+[[nodiscard]]
+constexpr auto intToStr(Integer v) noexcept {
+	constexpr auto Cap = [] {
+		auto out = 0;
+		switch (sizeof(Integer)) {
+			case 1:
+				out = 3;
+				break;
+			case 2:
+				out = 5;
+				break;
+			case 4:
+				out = 10;
+				break;
+			case 8:
+				out = 21;
+				break;
+		}
+		return out + ox::is_signed_v<Integer>;
+	}();
+	ox::IString<Cap> out;
+	std::ignore = out.resize(out.cap());
+	ox::CharBuffWriter w{{out.data(), out.cap()}};
+	std::ignore = writeItoa(v, w);
+	std::ignore = out.resize(w.tellp());
+	return out;
+}
+```
+
+##### StringParam
+
+```StringParam``` is a weird type.
+Because ```String::String(const char*)``` is explicit, it becomes a pain for
+functions to take ```String```s.
+
+```cpp
+struct Type {
+    ox::String m_s;
+    explicit Type(ox::String p): m_s(std::move(p)) {
+    }
+};
+
+void f() {
+    ox::String s{"asdf"};
+    Type t1{"asdf"};             // invalid - will not compile
+    Type t2{s};                  // invalid - will not compile
+    Type t3{std::move(s)};       // valid
+    Type t4{ox::String{"asdf"}}; // valid
+}
+```
+
+```StringParam``` has implicit conversion constructors, and will appropriately
+move from r-value ```String```s or create a ```String``` if not passed
+ownership of an existing ```String```.
+Think of ```StringParam``` as a way to opt-in to implicit instantiation with
+strings.
+
+```StringParam``` can access the string as a view through the ```view()```
+function, and the ```String``` inside can be accessed by moving from the
+```StringParam```.
+
+```cpp
+struct Type {
+    ox::String m_s;
+    explicit Type(ox::StringParam p): m_s(std::move(p)) {
+    }
+};
+
+void f() {
+    ox::String s{"asdf"};
+    Type t1{"asdf"};             // valid
+    Type t2{s};                  // valid
+    Type t3{std::move(s)};       // valid
+    Type t4{ox::String{"asdf"}}; // valid
+}
+```
+
+#### String View Types
+
+##### StringView
+
+```ox::StringView``` is Ox's version of ```std::string_view```.
+```StringView``` contains a pointer to a string, along with its size.
+
+This should be the normal type taken when a function needs a string that will
+exist until it returns.
+
+##### CStringView
+
+```CStringView``` is like ```StringView```, but it comes with the promise that
+the string ends with a null terminator.
+Accordingly, it has a ```c_str()``` function in addition to the ```data()```
+function that ```StringView``` has.
+
+```CStringView``` should be used when wrapping a C API that only takes C
+strings.
+
+##### StringLiteral
+
+```StringLiteral``` is a string view type, but it kind of straddles the line
+between view and store types.
+Creating a ```StringLiteral``` is a promise that you are passing a string
+literal into the constructor.
+This means you can treat it like a store, that can be safely used as a copy of
+the data.
+Functions that take ```StringLiteral```s are allowed to assume that the data
+will have no lifetime concerns and hold onto it without any need to make a
+copy.
+It has a consteval constructor to enforce the promise that it is a compile time
+string.
+
+```cpp
+void f(ox::StringLiteral const&);
+
+int main() {
+    f("123456789");                     // valid
+    f(ox::String{"123456789"}.c_str()); // invalid - will not compile
+}
+```
+
+#### Other Variants
+
+There are a few convenience aliases as well.
+
+* StringCR = String const&
+* StringViewCR = StringView const&
+* CStringViewCR = CStringView const&
+* CString = const char*
+
+String views do not generally need const references, but it does make debugging
+easier, as we can skip the constructor call if a string view already exists.
+
+These kind of aliases probably should not exist for most types, but strings are
+fundamental and ease of use is desirable.
+
 ### Logging and Output
 
 Ox provides for logging and debug prints via the ```oxTrace```, ```oxDebug```, and ```oxError``` macros.
