 ## Code organization
 
-cpp11 is a header only library, so all source code exposed to users lives in [inst/include](https://github.com/r-lib/cpp11/tree/master/inst/include).
-R code used to register functions and for `cpp11::cpp_source()` is in [R/](https://github.com/r-lib/cpp11/tree/master/R).
-Tests for _only_ the code in `R/` is in [tests/testthat/](https://github.com/r-lib/cpp11/tree/master/tests/testthat)
-The rest of the code is in a separate [cpp11test/](https://github.com/r-lib/cpp11/tree/master/cpp11test) package included in the source tree.
-Inside [cpp11test/src](https://github.com/r-lib/cpp11/tree/master/cpp11test/src) the files that start with `test-` are C++ tests using the [Catch](https://testthat.r-lib.org/reference/use_catch.html) support in testthat.

 The template parameter is the type of **value** the particular R vector stores, e.g. `double` for `cpp11::doubles`.
 This differs from Rcpp, whose first template parameter is the R vector type, e.g. `REALSXP`.
 
 The file first has the class declarations, then function definitions further down in the file.

 This is definitely the most complex part of the cpp11 code, with extensive use of [template metaprogramming](https://en.wikipedia.org/wiki/Template_metaprogramming).
 In particular the [substitution failure is not an error (SFINAE)](https://en.wikipedia.org/wiki/Substitution_failure_is_not_an_error) technique is used to control overloading of the functions.

 ### Unwind Protect
 
 In R 3.5+ cpp11 uses `R_UnwindProtect` to protect (most) calls to the R API that could fail.
 These are usually those that allocate memory, though in truth most R API functions could error along some paths.
 If an error happends under `R_UnwindProtect` cpp11 will throw a C++ exception.
-This exception is caught by the try catch block defined in the `BEGIN_CPP11` macro in [cpp11/declarations.hpp](https://github.com/r-lib/cpp11/blob/master/inst/include/cpp11/declarations.hpp).
+This exception is caught by the try catch block defined in the `BEGIN_CPP11` macro in [cpp11/declarations.hpp](https://github.com/r-lib/cpp11/blob/main/inst/include/cpp11/declarations.hpp).
 The exception will cause any C++ destructors to run, freeing any resources held by C++ objects.
 After the try catch block exits the R error unwinding is then continued by `R_ContinueUnwind()` and a normal R error results.
