+# Building WiredTiger with CMake
+> *CMake support for building wiredtiger is an active work-in-progress. As of this time CMake can **only** build the WiredTiger library for POSIX platforms (Linux & Darwin) on x86 hosts. We suggest you continue using the autoconf build until further support is added.*
+
+### Build Dependencies
+
+To build with CMake we **require** the following dependencies:
+
+* `cmake` : Official CMake install instructions found here: https://cmake.org/install/
+  * *WiredTiger supports CMake 3.11+*
+* `ninja` : Official ninja install instructions found here: https://ninja-build.org/
+
+We also strongly suggest the following dependencies are also installed (for improved build times):
+
+* `ccache` : Official ccache download instructions found here: https://ccache.dev/download.html
+
+##### Package Manager Instructions
+
+Alternatively you can use your system's package manager to install the dependencies listed above. Depending on the system, the following commands can be run:
+
+###### Install commands for Ubuntu & Debian (tested on Ubuntu 18.04)
+
+```bash
+sudo apt-get install cmake cmake-curses-gui
+sudo apt-get install ccache
+sudo apt-get install ninja-build
+```
+
+###### Install commands for Mac (using HomeBrew)
+
+```bash
+brew install ninja
+brew install ccache
+brew install cmake
+```
+
+
+
+### Building the WiredTiger Library
+
+> *The below commands are written for Linux and Darwin hosts. Windows instructions coming soon!*
+
+Building the WiredTiger library is relatively straightforward. Navigate to the top level of the WiredTiger repository and run the following commands:
+
+###### Configure your build
+
+```bash
+# Create a new directory to run your build from
+$ mkdir build && cd build
+# Run the cmake configure step. Note: '-G Ninja' tells CMake to generate a ninja build
+$ cmake -G Ninja ../.
+...
+-- Configuring done
+-- Generating done
+-- Build files have been written to: /home/wiredtiger/build
+```
+
+*See [Configuration Options](#configuration-options) for additional configuration options.*
+
+###### Run your build
+
+In the same directory you configured your build, run the `ninja` command to start the build:
+
+```bash
+$ ninja
+...
+[211/211 (100%) 2.464s] Creating library symlink libwiredtiger.so
+```
+
+*Note: Ninja doesn't need a `-j` option; it knows how many cores are available.*
+
+###### Configuration Options
+
+There are a number of additional configuration options you can pass to the CMake configuration step. A summary of some important options you will come to know:
+
+* `-DENABLE_STATIC=1` : Compile WiredTiger as a static library
+* `-DENABLE_LZ4=1` : Build the lz4 compressor extension
+* `-DENABLE_SNAPPY=1` : Build the snappy compressor extension
+* `-DENABLE_ZLIB=1` : Build the zlib compressor extension
+* `-DENABLE_ZSTD=1` : Build the libzstd compressor extension
+* `-DHAVE_DIAGNOSTIC=1` : Enable WiredTiger diagnostics
+* `-DHAVE_ATTACH=1` : Enable to pause for debugger attach on failure
+* `-DENABLE_STRICT=1` : Compile with strict compiler warnings enabled
+* `-DCMAKE_INSTALL_PREFIX=<path-to-install-directory>` : Path to install directory
+
+---
+
+An example of using the above configuration options during the configuration step:
+
+```bash
+$ cmake -DENABLE_STATIC=1 -DENABLE_LZ4=1 -DENABLE_SNAPPY=1 -DENABLE_ZLIB=1 -DENABLE_ZSTD=1 -DHAVE_DIAGNOSTIC=1 -DHAVE_ATTACH=1 -DENABLE_STRICT=1 -G Ninja ../.
+```
+
+---
+
+You can further look at all the available configuration options (and also dynamically change them!) by running `ccmake` in your build directory:
+
+```bash
+$ cd build
+$ ccmake .
+```
+
+*The configuration options can also be viewed in `build_cmake/configs/base.cmake`*.
+
+###### Switching between GCC and Clang
+
+By default CMake will use your default system compiler (`cc`). If you want to use a specific toolchain you can pass a toolchain file! We have provided a toolchain file for both GCC (`build_cmake/toolchains/gcc.cmake`) and Clang (`build_cmake/toolchains/clang.cmake`). To use either toolchain you can pass the `-DCMAKE_TOOLCHAIN_FILE=` to the CMake configuration step. For example:
+
+*Using the GCC Toolchain*
+
+```bash
+$ cd build
+$ cmake -DCMAKE_TOOLCHAIN_FILE=../build_cmake/toolchains/gcc.cmake -G Ninja ../.
+```
+
+*Using the Clang Toolchain*
+
+```bash
+$ cd build
+$ cmake -DCMAKE_TOOLCHAIN_FILE=../build_cmake/toolchains/clang.cmake -G Ninja ../.
+```

+# Hooks Overview
+#
+# Here are some useful terms to know, with some commentary for each.
+#
+#   API functions
+#      potentially any WiredTiger API functions that a hook creator wishes to modify (like
+#      Session.rename).  In Python most everything is an object.  Of course an instance of
+#      "Session" is an object, but also the "Session" class itself is an object.  The Session.rename
+#      function is also an object (of a certain form that can be called).  Also in Python,
+#      attributes on an object don't have to be "pre-declared", they can be created at any time.
+#      So it's easy to imagine assigning Session._rename_orig to be (the original value of)
+#      Session.rename, and then assigning Session.rename to be some other function object, that
+#      knows how to do something and then perhaps calls Session._rename_orig .  This is the
+#      essence of the hook concept.
+#
+#  Hook Creator:
+#      A way to attach a set of "behavior modifications" to various API functions.  More precisely,
+#      a hook creator derives from WiredTigerHookCreator and sets up a number of "hook functions",
+#      that are actions that are done either just before, after, or instead of, an API function.
+#      A XxxxHookCreator lives in a hook_xxxx.py file.  When a HookCreator is loaded, it may be
+#      given an optional argument.  This argument comes from the original python command line.
+#      For example, "python run.py --hook abc" loads hook_abc.py (where it expects to find a hook).
+#      "python run.py --hook abc=123" loads hook_abc.py with an argument "123".
+#
+#  Hook Function:
+#      One function that will be called before, after or instead of, an API function.  A hook
+#      function will be bound to an API function.  It is the job of the HookCreator to set up that
+#      binding.  It is possible to have multiple hook functions bound to the same API function.
+#      A hook function that replaces an API function will have the same args as the function
+#      it replaces (but there is a trick to give it additional context if needed -
+#      see session_create_replace in hook_demo.py).
+
+# For every API function altered, there is one of these objects
+# stashed in the <class>._<api_name>_hooks attribute.

+# The hook manager class.  There is only one hook manager.  It is responsible for finding all the
+# HookCreators at the beginning of the run, and calling setup_hooks() for each one, to have it bind
+# hook functions to API functions.  The hook manager is initialized with a list of hook names. Each
+# name is expanded, for example, "demo" causes the hook manager to load hook_demo.py, and to call
+# the "initialize" global function in that file.  We expect "initialize" to return a list of objects
+# (hooks) derived from WiredTigerHook (class defined below).  Generally, "initialize" returns a
+# single object (setting up some number of "hook functions") but to allow flexibility for different
+# sorts of packaging, we allow any number of hooks to be returned.
