+Building project
+================
+
+The resolver isn't yet available in the repositories, so you can either build it from sources or use
+official `Docker images`_.
+
+Platform considerations
+-----------------------
+
+.. csv-table::
+   :header: "Project", "Platforms", "Compatibility notes"
+
+   "``daemon``", "UNIX-like [*]_, Microsoft Windows", "C99, libuv_ provides portable I/O"
+   "``library``", "UNIX-like, Microsoft Windows [*]_ ", "MSVC_ not supported (requires ``__attribute__((cleanup))`` and GNU99), needs MinGW_"
+   "``modules``", "*varies*", ""
+   "``unit tests``", "*equivalent to library*", ""
+   "``integration tests``", "UNIX-like", "Depends on ELF/Mach-O (flat namespace) semantics for library injection"
+
+.. [*] Known to be running (not exclusively) on FreeBSD, Linux and OS X.
+.. [*] Modules are not supported yet, as the PE/DLL loading is different.
+
+Requirements
+------------
+
+The following is a list of software required to build Knot DNS Resolver, alternatively you can use
+the `Docker images`.
+
+.. csv-table:: Mandatory requirements.
+   :header: "Requirement", "Required by", "Notes"
+
+   "`GNU Make`_ 3.80+", "*all*", "*(build only)*"
+   "C compiler", "*all*", "*(build only)* [*]_ )"
+   "libknot_ 2.0+", "*all*", "Knot DNS library."
+
+.. csv-table:: Optional requirements.
+   :header: "Requirement", "Required by", "Notes"
+
+   "`pkg-config`_", "*all*", "*(build only, optional)*"
+   "libuv_ 1.0+", "``daemon``", "Multiplatform I/O and services."
+   "cmocka_", "``unit tests``", "Unit testing framework."
+   "Python_", "``integration tests``", "For scripting tests, C header files are required (``python-dev``)"
+   "GCCGO_",  "``Go modules``", "For building Go modules, see modules documentation."
+
+.. [*] Requires C99, ``__attribute__((cleanup))`` and ``-MMD -MP`` for dependency file generation. GCC, Clang and ICC are supported.
+
+Docker image
+~~~~~~~~~~~~
+
+Docker images require only either Linux or a Linux VM (see boot2docker_ on OS X).
+
+.. code-block:: bash
+
+	$ docker run cznic/knot-resolver
+
+See the build page https://registry.hub.docker.com/u/cznic/knot-resolver for more information and options.
+You can hack on the container by changing the container entrypoint to shell like:
+
+.. code-block:: bash
+
+	$ docker run -it --entrypoint=/bin/bash cznic/knot-resolver
+
+Building from sources 
+~~~~~~~~~~~~~~~~~~~~~
+
+The Knot DNS Resolver depends on the development version of the Knot DNS library, and a reasonably recent version of `libuv`.
+Several dependencies may not be in the packages yet, the script pulls and installs all dependencies in a chroot.
+
+.. code-block:: bash
+
+	$ make info # See what's missing
+
+You can avoid rebuilding dependencies by specifying `BUILD_IGNORE` variable, see the Dockerfile_ for example.
+Usually you only really need to rebuild `libknot`.
+
+.. code-block:: bash
+	$ export FAKEROOT="${HOME}/.local"
+	$ export PKG_CONFIG_PATH="${FAKEROOT}/lib/pkgconfig"
+	$ export BUILD_IGNORE="..." # Ignore installed dependencies
+	$ ./scripts/bootstrap-depends.sh ${FAKEROOT}
+
+Now you can build, test and install.
+
+.. code-block:: bash
+
+	$ make
+	$ make check
+	$ make install
+
+Alternatively you can build only specific parts of the project, i.e. ``library``:
+
+.. code-block:: bash
+	$ make lib
+	$ make lib-install
