+## [1.3.0] 2020-05-30
+
+### Added
+
+- Support for Ubuntu 20.04 and CentOS 8.
+
+## [1.2.1] 2019-12-25
+
+### Fixed
+
+- macOS support.
+
+## [1.2.0] 2019-11-15
+
+### Added
+
+- Flag for Verbose output. Right now only qemu status messages is
+  implemented.
+
+### Fixed
+
+- Kpti settings was not affected for regular runs.
+
+## [1.1.2] 2019-09-05
+
+### Added
+
+- Added policykit-1 to rootfs for Ubuntu.
+
+### Fixed
+
+- Avoided slow mirrors with use of mirror://mirrors.ubuntu.com for
+  Ubuntu 16.04 and newer.
+
+## [1.1.1] 2019-08-31
+
+### Fixed
+
+- macOS support.
+
+## [1.1.0] 2019-08-30
+
+### Added
+
+- Global configuration file (~/.out-of-tree/out-of-tree.toml) allow to
+  set up default values for settings.
+
+- rootfs generator for Ubuntu 14.04.
+
+- Parameter for setting up docker registry server.
+
+- Support for (distro-specific) custom docker commands that will be
+  executed before the base template.
+
+- Parameter for setting up a reliability threshold for exit code.
+
+- Parameter for setting up global timeout, after which no new tasks
+  will be started.
+
+### Fixed
+
+- Spelling in output.
+
+- Now kernel generation will not fail if there are no directory
+  /lib/modules inside the container.
+
+## [1.0.0] 2019-08-20
+
+### Added
+
+- New parameter `--max=X` is added for `autogen` (generate kernels
+  base on `.out-of-tree.toml` definitions) and `pew` (automated
+  runs) and allows to specify a maximum number of runs per each
+  supported kernel in module/exploit definition.
+
+- New command `genall` -- generate all kernels for specified
+  distro/version.
+
+- All logs stores in sqlite3 database. Implemented specific commands
+  for making simple queries and export data to markdown and json.
+
+- Implemented success rate calculation for previous runs.
+
+- Save of build results supported by parameter `--dist` for `pew`.
+
+- Support for generating kernels info from host system.
+
+- Support for build on host.
+
+- Support for custom kernels.
+
+- Now debugging environment is automatically looking for debug
+  kernel on the host system.
+
+- Added ability to enable/disable kaslr/smep/smap/kpti for debugging
+  by command line flags.
+
+- New parameter `--threads=N` is added for `pew` and allows to
+  specify maximum number of threads that will be used for parallel
+  build/run/test.
+
+- Tagging for runs. Tags write to log and can be used for
+  statistics.
+
+- Added non-regex way to set kernel version in .out-of-tree.toml (see
+  examples).
+
+- New command `pack` that perform tests in subdirectories.
+
+- Added ability to disable kaslr/smep/smap/kpti for in artifact
+  definition.
+
+- Added ability to change amount of memory/CPUs and set qemu timeout
+  in artifact definition (`.out-of-tree.toml`).
+
+- Now images downloading while `kernel autogen`, bootstrap is not
+  required anymore.
+
+- Support CentOS kernels.
+
+### Changed
+
+- Now if there's no base image found — out-of-tree will try to use
+  an image from closest previous version, e.g. image from Ubuntu
+  18.04 for Ubuntu 18.10.
+
+- Kernel modules tests will not be failed if there are no tests
+  exists.
+
+- Now *out-of-tree* will return negative error code if at least one
+  of the stage was failed.
+
+- Project is switch to use Go modules.
+
+- Now test.sh is used by default if copying is not implemented in
+  Makefile.
+
+- dmesg is not cleaned before the start of module/exploit anymore.
+
+- qemu/kvm will use all host cpu features.
+
+### Removed
+
+- *Kernel factory* is removed completely in favor of incremental
+  Dockerfiles.
+
+- `bootstrap` is not doing anything anymore. It'll be removed in next
+  release.
+
+### Fixed
+
+- Command `timeout` is not required anymore.
+
+- Errors is more meaningful.
+
+- Temporary files is moved to `~/.out-of-tree/tmp/` to avoid docker
+  mounting issues on some systems.
+
+## [0.2.0] - 2019-12-01
+
+The main purpose of the release is to simplify installation.
+
+### Changes
+
+- All configuration moved to `~/.out-of-tree`.
+
+- Now prebuilt images can be downloaded with bootstrap.
+
+- Ability to generate kernels specific to .out-of-tree.toml in
+  current directory. So now there's no need to wait for several
+  hours for start work on specific kernel with module/exploit.
+
+- Now there's no need to keep source tree and _out-of-tree_ can be
+  distributed in binary form.
+
+- New command: **debug**. Creates interactive environment for kernel
+  module/exploit development. Still work-in-progress.
+
+- No warning anymore if test.sh is not exists.
+
+## [0.1.0] - 2019-11-20
+
+Initial release that was never tagged.
+
+Refer to state after first public release on ZeroNights 2018

 ## Installation
 
-    $ go get github.com/jollheef/out-of-tree
-    $ out-of-tree bootstrap
+### GNU/Linux (with [Nix](https://nixos.org/nix/))
 
-Then you can check it on kernel module example:
+    $ curl -fsSL https://get.docker.com | sh
+	$ sudo usermod -aG docker user && newgrp docker
+    $ curl https://nixos.org/nix/install | sh
+    $ nix-env -iA nixpkgs.out-of-tree
 
-    $ cd $GOPATH/github.com/jollheef/out-of-tree/examples/kernel-module
-    $ out-of-tree kernel autogen # generate kernels based on .out-of-tree.toml
-    $ out-of-tree pew
+Note that adding a user to group *docker* has serious security implications. Check Docker documentation for more information.
+
+### macOS
+
+    $ brew cask install docker
+    $ open --background -a Docker && sleep 1m
+    $ brew tap jollheef/repo
+    $ brew install out-of-tree
+
+Read [documentation](https://out-of-tree.readthedocs.io) for further info.

+===========
+
+*out-of-tree* is the kernel {module, exploit} development tool.
+
+*out-of-tree* was created on the purpose of decreasing complexity of
+environment for developing, testing and debugging Linux kernel
+exploits and out-of-tree kernel modules (that's why tool got a name
+"out-of-tree").
+
+While I'm trying to keep that documentation up-to-date, there may be
+some missing information. Use ``out-of-tree --help-long`` for checking
+all features.
+
+If you found anything missed here, please make a pull request or send
+patches to patch@dumpstack.io.
+
+If you need personal support, your company is interested in the
+project or you just want to share some thoughts -- feel free to write

+Introduction
+============
+
+*out-of-tree* is written in *Go*, it uses *Docker* for generating
+kernel/filesystem images and *Qemu* for virtualization.
+
+Also it possible to generate kernels from the host system and use the
+custom one.
+
+*out-of-tree* supports *GNU/Linux* (usually it's tested on NixOS and
+latest Ubuntu LTS) and *macOS*. Technically all systems that supported
+by Go, Docker, and Qemu must work well. Create the issue if you'll
+notice any issue in integration for your operating system.
+
+All *Qemu* interaction is stateless.
+
+*out-of-tree* is allow and require metadata (``.out-of-tree.toml``)
+for work. TOML (Tom's Obvious, Minimal Language) is used for kernel
+module/exploit description.
+
+``.out-of-tree.toml`` is mandatory, you need to have in the current
+directory (usually, it's a project of kernel module/exploit) or use
+the ``--path`` flag.
+
+Files
+-----
+
+All data is stored in ``~/.out-of-tree/``.
+
+- *db.sqlite* contains logs related to run with ``out-of-tree pew``,
+  debug mode (``out-of-tree debug``) is not store any data.
+
+- *images* used for filesystem images (rootfs images that used for
+  ``qemu -hda ...``) that can be generated with the
+  ``tools/qemu-*-img/...``.
+
+- *kernels* stores all kernel ``vmlinuz/initrd/config/...`` files that
+  generated previously with a some *Docker magic*.
+
+- *kernels.toml* contains metadata for generated kernels. It's not
+  supposed to be edited by hands.
+
+- *kernels.user.toml* is default path for custom kernels definition.
+
+- *Ubuntu* (or *Centos*/*Debian*/...) is the Dockerfiles tree
+  (DistroName/DistroVersion/Dockerfile). Each Dockerfile contains a
+  base layer and incrementally updated list of kernels that must be
+  installed.
+
+Overview
+---------
+
+*out-of-tree* creating debugging environment based on **defined** kernels::
+
+    $ out-of-tree debug --kernel 'Ubuntu:4.15.0-58-generic'
+    [*] KASLR SMEP SMAP
+    [*] gdb is listening on tcp::1234
+    [*] build result copied to /tmp/exploit
+
+    ssh -o StrictHostKeyChecking=no -p 29308 root@127.133.45.236
+    gdb /usr/lib/debug/boot/vmlinux-4.15.0-58-generic -ex 'target remote tcp::1234'
+
+    out-of-tree> help
+    help    : print this help message
+    log     : print qemu log
+    clog    : print qemu log and cleanup buffer
+    cleanup : cleanup qemu log buffer
+    ssh     : print arguments to ssh command
+    quit    : quit
+    out-of-tree>
+
+*out-of-tree* uses three stages for automated runs:
+
+- Build
+
+  - Inside the docker container (default).
+  - Binary version (de facto skip stage).
+  - On host.
+
+- Run
+
+  - Insmod for the kernel module.
+  - This step is skipped for exploits.
+
+- Test
+
+  - Run the test.sh script on the target machine.
+  - Test script is run from *root* for the kernel module.
+  - Test script is run from *user* for the kernel exploit.
+  - Test script for the kernel module is fully custom (only return
+    value is checked).
+  - Test script for the kernel exploit receives two parameters:
+
+    - Path to exploit
+    - Path to file that must be created with root privileges.
+
+  - If there's no test.sh script then default
+    (``echo touch FILE | exploit``) one is used.
+
+Security
+--------
+
+*out-of-tree* is not supposed to be used on multi-user systems or with
+an untrusted input.
+
+Meanwhile, all modern hypervisors are supporting nested
+virtualization, which means you can use it for isolating *out-of-tree*
+if you want to work with an untrusted input (e.g. with a mass-scale
+testing public proofs-of-concept).
