+## Exceptions
+
+All the exceptions thrown by toml11 inherits `toml::exception` that inherits
+`std::exception`.
+
+```cpp
+namespace toml {
+struct exception      : public std::exception  {/**/};
+struct syntax_error   : public toml::exception {/**/};
+struct type_error     : public toml::exception {/**/};
+struct internal_error : public toml::exception {/**/};
+} // toml
+```
+
+`toml::exception` has `toml::exception::location()` member function that returns
+`toml::source_location`, in addition to `what()`.
+
+```cpp
+namespace toml {
+struct exception : public std::exception
+{
+    // ...
+    source_location const& location() const noexcept;
+};
+} // toml
+```
+
+It represents where the error occurs.
