APT is maintained in git, the official repository being located at
-`git://anonscm.debian.org/apt/apt.git` ([webgit](http://anonscm.debian.org/gitweb/?p=apt/apt.git)),
+`git://anonscm.debian.org/apt/apt.git` ([webgit](https://anonscm.debian.org/git/apt/apt.git)),
but also available at other locations like [GitHub](https://github.com/Debian/apt).

different stages of completion might be branched of from those, which you
are encouraged to do as well.
### Coding
-APT uses its own autoconf based build system, see [README.make](http://anonscm.debian.org/gitweb/?p=apt/apt.git;a=blob;f=README.make)
-for the glory details, but to get started, just run:
+APT uses cmake. To start building, you need to run
- $ make
+ cmake <path to source directory>
-from a fresh git checkout.
+from a build directory. For example, if you want to build in the source tree,
+run:
+
+ cmake .
+
+Then you can use make as you normally would (pass -j <count> to perform <count>
+jobs in parallel).
+
+You can also use the Ninja generator of cmake, to do that pass
+ -G Ninja
+to the cmake invocation, and then use ninja instead of make.
The source code uses in most parts a relatively uncommon indent convention,
-namely 3 spaces with 8 space tab (see [doc/style.txt](http://anonscm.debian.org/gitweb/?p=apt/apt.git;a=blob;f=doc/style.txt) for more on this).

Adhering to it avoids unnecessary code-churn destroying history (aka: `git blame`)
and you are therefore encouraged to write patches in this style.
Your editor can surely help you with this, for vim the settings would be
### Manual execution
-When you make changes and want to run them manually, make sure your
-`$LD_LIBRARY_PATH` points to the libraries you have built, e.g. via:
-
- $ export LD_LIBRARY_PATH=$(pwd)/build/bin
- $ ./build/bin/apt-get moo
-
+When you make changes and want to run them manually, you can just do so. CMake
+automatically inserts an rpath so the binaries find the correct libraries.
### Integration tests
### Unit tests
-These tests are gtest-dev based, reside in `./test/libapt` and can be run with `make test`.
-They are executed at package build-time, but not by `make`.
+These tests are gtest-dev based, executed by ctest, reside in `./test/libapt`

+failed, so to see more details you can also run them with `ctest --verbose`.
