+## Code constructs to watch out for
 
- *this document is still in-progress...*
+This section is a (sadly incomplete) listing of various constructs that
+are problematic and are not always caught by our CI infrastructure.
+
+### Naked exceptions and exceptions-related function
+
+If you are throwing an exception, it should be done via `CATCH_ERROR`
+or `CATCH_RUNTIME_ERROR` in `catch_enforce.h`. These macros will handle
+the differences between compilation with or without exceptions for you.
+However, some platforms (IAR) also have problems with exceptions-related
+functions, such as `std::current_exceptions`. We do not have IAR in our
+CI, but luckily there should not be too many reasons to use these.
+However, if you do, they should be kept behind a
+`CATCH_CONFIG_DISABLE_EXCEPTIONS` macro.
+
+### Unqualified usage of functions from C's stdlib
+
+If you are using a function from C's stdlib, please include the header
+as `<cfoo>` and call the function qualified. The common knowledge that
+there is no difference is wrong, QNX and VxWorks won't compile if you
+include the header as `<cfoo>` and call the function unqualified.
+
+

+
+_This documentation will always be in-progress as new information comes
+up, but we are trying to keep it as up to date as possible._

+## Logging without local scope
+
+`UNSCOPED_INFO` is similar to `INFO` with two key differences:
+
+- Lifetime of an unscoped message is not tied to its own scope.
+- An unscoped message can be reported by the first following assertion only, regardless of the result of that assertion.
+
+In other words, lifetime of `UNSCOPED_INFO` is limited by the following assertion (or by the end of test case/section, whichever comes first) whereas lifetime of `INFO` is limited by its own scope.
+
+These differences make this macro useful for reporting information from helper functions or inner scopes. An example:
+
+```cpp
+void print_some_info() {
+    UNSCOPED_INFO("Info from helper");
+}
+
+TEST_CASE("Baz") {

+

+These test cases have similar syntax like [type parametrised test cases](#type-parametrised-test-cases), with one

+### Signature
+Signature has some strict rules for these tests cases to work properly:
+* signature with multiple template parameters e.g. `typename T, size_t S` must have this format in test case declaration
+  `((typename T, size_t S), T, S)`
+* signature with variadic template arguments e.g. `typename T, size_t S, typename...Ts` must have this format in test case declaration

+* signature with single non type template parameter e.g. `int V` must have this format in test case declaration `((int V), V)`
+* signature with single type template parameter e.g. `typename T` should not be used as it is in fact `TEMPLATE_TEST_CASE`
+
+Currently Catch2 support up to 11 template parameters in signature

+
+## Floating point precision
+
+Catch provides a built-in `StringMaker` specialization for both `float`
+and `double`. By default, it uses what we think is a reasonable precision,
+but you can customize it by modifying the `precision` static variable
+inside the `StringMaker` specialization, like so:
+
+```cpp
+        Catch::StringMaker<float>::precision = 15;
+        const float testFloat1 = 1.12345678901234567899f;
+        const float testFloat2 = 1.12345678991234567899f;
+        REQUIRE(testFloat1 == testFloat2);
+```
+
+This assertion will fail and print out the `testFloat1` and `testFloat2`
+to 15 decimal places.

+Although this was a simple test it's been enough to demonstrate a few things about how Catch is used. Let's take a moment to consider those before we move on.
 
 1. All we did was ```#define``` one identifier and ```#include``` one header and we got everything - even an implementation of ```main()``` that will [respond to command line arguments](command-line.md#top). You can only use that ```#define``` in one implementation file, for (hopefully) obvious reasons. Once you have more than one file with unit tests in you'll just ```#include "catch.hpp"``` and go. Usually it's a good idea to have a dedicated implementation file that just has ```#define CATCH_CONFIG_MAIN``` and ```#include "catch.hpp"```. You can also provide your own implementation of main and drive Catch yourself (see [Supplying-your-own-main()](own-main.md#top)).
 2. We introduce test cases with the ```TEST_CASE``` macro. This macro takes one or two arguments - a free form test name and, optionally, one or more tags (for more see <a href="#test-cases-and-sections">Test cases and Sections</a>, ). The test name must be unique. You can run sets of tests by specifying a wildcarded test name or a tag expression. See the [command line docs](command-line.md#top) for more information on running tests.
