* reorder sections so we have a more newbie friendly reading flow:
  requirements -> building -> running

* add links to documentation

* drop mentions of autotools

* drop piglit references

* don't list dependencies, just point to Dockerfiles

* mention IGT containers

 IGT GPU Tools
 =============

 Description
 -----------

@@ -12,173 +13,31 @@ complicated build procedures or specific testing environments to get useful
 results. Therefore, IGT GPU Tools includes low-level tools and tests
 specifically for development and testing of the DRM Drivers.

-IGT GPU Tools is split into several sections:
-
-**benchmarks/**
-
-This is a collection of useful microbenchmarks that can be used to tune
-DRM code in relevant ways.
-
-The benchmarks require KMS to be enabled.  When run with an X Server
-running, they must be run as root to avoid the authentication
-requirement.
-
-Note that a few other microbenchmarks are in tests (like gem_gtt_speed).
-
-**tests/**
-
-This is a set of automated tests to run against the DRM to validate
-changes. Many of the tests have subtests, which can be listed by using
-the --list-subtests command line option and then run using the
---run-subtest option. If --run-subtest is not used, all subtests will
-be run. Some tests have futher options and these are detailed by using
-the --help option.
-
-The test suite can be run using the run-tests.sh script available in
-the scripts directory. Piglit is used to run the tests and can either
-be installed from your distribution (if available), or can be
-downloaded locally for use with the script by running:
-
-    ./scripts/run-tests.sh -d
-
-run-tests.sh has options for filtering and excluding tests from test
-runs:
-
-  -t <regex>      only include tests that match the regular expression
-  -x <regex>      exclude tests that match the regular expression
-
-Useful patterns for test filtering are described in the API
-documentation and the full list of tests and subtests can be produced
-by passing -l to the run-tests.sh script.
-
-Results are written to a JSON file and an HTML summary can also be
-created by passing -s to the run-tests.sh script. Further options are
-are detailed by using the -h option.
-
-
-If not using the script, piglit can be obtained from:
-
-    git://anongit.freedesktop.org/piglit
-
-There is no need to build and install piglit if it is only going to be
-used for running i-g-t tests.
-
-Set the IGT_TEST_ROOT environment variable to point to the tests
-directory, or set the path key in the "igt" section of piglit.conf to
-the igt-gpu-tools root directory.
-
-The tests in the i-g-t sources need to have been built already. Then we
-can run the testcases with (as usual as root, no other drm clients
-running):
-
-    piglit-sources # ./piglit run igt <results-file>
-
-The testlist is built at runtime, so no need to update anything in
-piglit when adding new tests. See
-
-    piglit-sources $ ./piglit run -h
-
-for some useful options.
-
-Piglit only runs a default set of tests and is useful for regression
-testing. Other tests not run are:
-- tests that might hang the gpu, see HANG in Makefile.am
-- gem_stress, a stress test suite. Look at the source for all the
-  various options.
-- testdisplay is only run in the default mode. testdisplay has tons of
-  options to test different kms functionality, again read the source for
-  the details.
-
-**lib/**
-
-Common helper functions and headers used by the other tools.
-
-**man/**
-
-Manpages, unfortunately rather incomplete.
-
-**tools/**
-
-This is a collection of debugging tools that had previously been
-built with the 2D driver but not shipped.  Some distros were hacking
-up the 2D build to ship them.  Instead, here's a separate package for
-people debugging the driver.
-
-These tools generally must be run as root, except for the ones that just
-decode dumps.
-
-**docs/**
-
-Contains the automatically generated igt-gpu-tools libraries
-reference documentation in docs/reference/. You need to have the
-gtk-doc tools installed and use the "--enable-gtk-doc" configure flag
-to generate this API documentation.
-
-To regenerate the html files when updating documentation, use:
-
-    $ ninja -C build igt-gpu-tools-doc
-
-If you've added/changed/removed a symbol or anything else that changes
-the overall structure or indexes, this needs to be reflected in
-igt-gpu-tools-sections.txt. Entirely new sections will also need to be
-added to igt-gpu-tools-docs.xml in the appropriate place.
-
-**include/drm-uapi**
-
-Imported DRM uapi headers from airlied's drm-next branch.
-These should be updated all together by executing "make
-headers_install" from that branch of the kernel and then
-copying the resulting ./usr/include/drm/*.h in and committing
-with a note of which commit on airlied's branch was used to
-generate them.

 Requirements
 ------------

-This is a non-exhaustive list of package dependencies required for building
-the default configuration (package names may vary):
+See `Dockerfiles.*` for up-to-date list of packages names in Fedora and

+Debian.

-       gtk-doc-tools
-       flex

+If your distribution packages IGT you can also use your package manager to
+install the dependencies, e.g.:

-The following dependencies are required for building chamelium support
-(package names may vary):
+    # dnf builddep igt-gpu-tools

-       libxmlrpc-core-c3-dev
-       libudev-dev
-       libglib2.0-dev
-       libgsl-dev
+But keep in mind that this may be slightly outdated and miss some
+recently added dependencies for building the current master.

-The following dependencies are requires for building audio support
-(package names may vary):

-       libasound2-dev
-       libgsl-dev
+Building

-See Dockerfiles.* for package names in different distributions.
+Oneliner to get started:

-Meson build system support
---------------------------
-
-Currently we support both meson and automake as build systems, but meson is the
-recommended choice. Oneliner to get started:
-
-    $ mkdir build && meson build && cd build && ninja
+    $ meson build && ninja -C build

 Note that meson insist on separate build directories from the source tree.

@@ -186,26 +45,111 @@ Running selfchecks for lib/tests and tests/ is done with

     $ ninja -C build test

-Note that this doesn't actually run the testcases in tests/: scripts/run-tests.sh
-should continue to be used for that.
-
 Documentation is built using

     $ ninja -C build igt-gpu-tools-doc

-Note that this needs meson v0.47 or later, earlier versions of meson do not
-track depencies correctly for the documentation build and need:

-    $ ninja -C build && ninja -C build igt-gpu-tools-doc
+Running Tests
+-------------

-Note that there's a setup script similar to ./autogen.sh which creates a
-compatibility Makefile with a few useful default targets:
+In `tests/` you can find a set of automated tests to run against the DRM
+drivers to validate your changes. Many of the tests have subtests, which can

+Most of the test must be run as a root and with no X or Wayland compositor
+running.

+The test suite can be run using the `run-tests.sh` script available in the
+`scripts/` directory. To use it make sure that `igt_runner` is built, e.g.:
+
+    meson -Drunner=enabled build && ninja -C build
+
+`run-tests.sh` has options for filtering and excluding tests from test
+runs:
+
+    -t <regex>      only include tests that match the regular expression
+    -x <regex>      exclude tests that match the regular expression
+
+Useful patterns for test filtering are described in the [API
+documentation][API] and the full list of tests and subtests can be produced
+by passing `-l` to the `run-tests.sh` script. Further options are are
+detailed by using the `-h` option.
+
+Results are written to a JSON file.

+
+IGT Containers
+--------------
+
+IGT is packed into nifty docker-compatible containers for ease of execution
+and to avoid having to install all the dependencies. You can use
+podman/docker to to run it on your system.
+
+Oneliner to get you started with the latest master:
+
+    # podman run --rm --priviledged registry.freedesktop.org/drm/igt-gpu-tools/igt:master
