-## Download Builds (Windows)
+## [Download Stable/Beta Builds](https://github.com/k4yt3x/video2x/releases/latest) (Windows)
 
-You can go to the [releases page](https://github.com/k4yt3x/video2x/releases) to download the latest builds of `Video2X`. The exe files will require no Python or Python module installation.
+- **`Full`**: full package comes pre-configured with **all** dependencies like `FFmpeg` and `waifu2x-caffe`.
+- **`Light`**: ligt package comes with only Video2X binaries and a template configuration file. The user will either have to run the setup script or install and configure dependencies themselves.
 
-The **`full`** package provides all packages that will possibly be needed by `Video2X`, including `FFmpeg`, `waifu2x-caffe`, `waifu2x-converter-cpp`, `waifu2x-ncnn-vulkan`, `srmd-ncnn-vulkan` and `Anime4KCPP`. The config file (`video2x.yaml`) is also already configured for the environment. All you need to do is just to launch `video2x.exe`.
+Go to the **[Quick Start](#quick-start)** section for usages.
 
-The **`light`** package provides only the most basic functions of `Video2X`. Only `video2x.exe`, `video2x_setup.exe` and `video2x.yaml` are included. To setup dependencies (e.g. `FFmpeg` and `Waifu2X`) automatically, simply launch `video2x_setup.exe`.
+### [Download From Mirror](https://files.k4yt3x.com/Projects/Video2X/latest)
 
-## Prerequisites
+In case you're unable to download the releases directly from GitHub, you can try downloading from the mirror site hosted by the author. Only releases will be updated in this directory, not nightly builds.
 
-Component names that are **bolded** can be automatically downloaded and configured with the `video2x_setup.py` script.

-## Recent Changes
+Nightly builds are built automatically every time a new commit is pushed to the master branch. The lates nightly build is always up-to-date with the latest version of the code, but is less stable and may contain bugs. Nightly builds are handled by GitHub's integrated CI/CD tool, GitHub Actions.
 
-### 4.0.0 (May 5, 2020)
+To download the latest nightly build, go to the [GitHub Actions](https://github.com/k4yt3x/video2x/actions) tab, enter the last run of workflow "Video2X Nightly Build, and download the artifacts generated from the run.
 
-- Added internationalization support
-  - Added language zh_CN (简体中文)

-- Driver-specific settings can now be specified in the command line by specifying them after a `--`
-- All driver-specific settings are parsed by the corresponding driver
-- Modularized driver wrappers in Video2X
-- Cleaned up some clutters in the code
+## [Docker Image](https://hub.docker.com/r/k4yt3x/video2x)
 
-### 3.2.0 (April 26, 2020)
+Video2X Docker images are available on Docker Hub for easy and rapid Video2X deployment on Linux and macOS. If you already have Docker installed, then only one command is needed to start upscaling a video. For more information on how to use Video2X's Docker image, please refer to the [documentations](https://github.com/K4YT3X/video2x/wiki/Docker).
 
-- Added support for [SRMD-NCNN-Vulkan](https://github.com/nihui/srmd-ncnn-vulkan)
+## Introduction
 
-### 3.1.0 (February 26, 2020)
+Video2X is a video/GIF/image upscaling software based on Waifu2X, Anime4K, SRMD and RealSR written in Python 3. It upscales videos, GIFs and images, restoring details from low-resolution inputs. Video2X also accepts GIF input to video output and video input to GIF output.
 
-- Removed the redundant layer of multi-threading since multi-process has to be implemented for launching Windows PE files in sub-processes
-- Added support for graceful exit upon `KeyboardInterrupt` or termination signals
-- Other minor improvements such as replacing `' '.join(execute)` with `shlex.join(execute)`
+Currently, Video2X supports the following drivers (implementations of algorithms).
 
-### Setup Script 1.8.0 (May 5, 2020)
+- **Waifu2X Caffe**: Caffe implementation of waifu2x
+- **Waifu2X Converter CPP**: CPP implementation of waifu2x based on OpenCL and OpenCV
+- **Waifu2X NCNN Vulkan**: NCNN implementation of waifu2x based on Vulkan API
+- **SRMD NCNN Vulkan**: NCNN implementation of SRMD based on Vulkan API
+- **RealSR NCNN Vulkan**: NCNN implementation of RealSR based on Vulkan API
+- **Anime4KCPP**: CPP implementation of Anime4K

+Before running Video2X, you'll need to ensure you have installed the drivers' external dependencies such as GPU drivers.
 
-### Installing Dependencies
+- waifu2x-caffe
+  - GPU mode: Nvidia graphics card driver
+  - cuDNN mode: Nvidia CUDA and [cuDNN](https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html#install-windows)
+- Other Drivers
+  - GPU driver if you want to use GPU for processing
 
-First, clone the video2x repository.
+### Running Video2X (GUI)
 
-```shell
-git clone https://github.com/k4yt3x/video2x.git
-cd video2x/src
-```
+The easiest way to run Video2X is to use the full build. Extract the full release zip file and you'll get these files.
 
-Then you may run the `video2x_setup.py` script to install and configure the dependencies automatically. This script is designed and tested on Windows 10.
+![Video2X Release Files](https://user-images.githubusercontent.com/21986859/81489846-28633380-926a-11ea-9e81-fb92f492e14c.png)\
+*Video2X release files*
 
-This script will install the newest version of `ffmpeg`, and all upscaling drivers to `%LOCALAPPDATA%\\video2x` and all required python libraries.
+Simply double click on video2x_gui.exe to launch the GUI.
 
-```shell
-python video2x_setup.py
-```

+*Video2X GUI main tab*
 
-Alternatively, you can also install the dependencies manually. Please refer to the prerequisites section to see what's needed.
+Then, drag the videos you wish to upscale into the window and select the appropriate output path.
 
-Then you'll need to install python dependencies before start using video2x. Install simply by executing the following command.
+![drag-drop](https://user-images.githubusercontent.com/21986859/81489880-7bd58180-926a-11ea-85ae-b72d2f4f5e72.png)\
+*Drag and drop file into Video2X GUI*
 
-```shell
-pip install -r requirements.txt
-```
+Tweak the settings if you want to, then hit the start button at the bottom and the upscale will start. Now you'll just have to wait for it to complete.

+7-Zip Plugin for FAR Manager
+----------------------------
+
+FAR Manager is a file manager working in text mode. 
+You can download "FAR Manager" from site:
+http://www.farmanager.com
+
+Files:
+
+far7z.txt     - This file
+far7z.reg     - Regisrty file for MultiArc Plugin
+7zToFar.ini   - Supporting 7z for MultiArc Plugin
+7-ZipFar.dll  - 7-Zip Plugin for FAR Manager

+7-ZipRus.hlf  - Help file in Russian for FAR Manager
+7-ZipEng.lng  - Plugin message strings in English for FAR Manager
+7-ZipRus.lng  - Plugin message strings in Russian for FAR Manager
+
+There are two ways to use 7-Zip with FAR Manager:
+
+  1) Via 7-Zip FAR Plugin (it's recommended way).
+  2) Via standard MultiArc Plugin.
+
+
+7-Zip FAR Plugin
+~~~~~~~~~~~~~~~~
+
+7-Zip FAR Plugin is first level plugin for FAR Manager, like MultiArc plugin.
+It very fast extracts and updates files in archive, since it doesn't use 
+external programs. It supports all formats supported by 7-Zip: 
+7z, ZIP, RAR, CAB, ARJ, GZIP, BZIP2, Z, TAR, CPIO, RPM and DEB.
+
+To install 7-Zip FAR Plugin:
+  1) Create "7-Zip" folder in ...\Program Files\Far\Plugins folder.
+  2) Copy all files from "FAR" folder of this package to created folder.
+  3) Install 7-Zip, or copy 7z.dll from 7-Zip to Program Files\Far\Plugins\7-Zip\
+  4) Restart FAR.
+
+You can open archives with one of the following ways:
+  * Pressing Enter.
+  * Pressing Ctrl-PgDown.
+  * Pressing F11 and selecting 7-Zip item.
+  
+  
+You can create new archives with 7-Zip by pressing F11 and 
+selecting 7-Zip (add to archive) item.
+
+If you think that some operations with archives is better to do with MultiArc Plugin,
+you can disable 7-Zip plugin via Options / Pligin configuration / 7-Zip. In such mode 
+opening archives by pressing Enter and Ctrl-PgDown will start MultiArc Plugin. And 
+if you want to open archive with 7-Zip, press F11 and select 7-Zip item.
+
+
+Using command line 7-Zip via MultiArc Plugin
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to use 7-Zip via MultiArc Plugin, you must
+register file far7z.reg.
+
+If you want to use 7z archives via MultiArc Plugin, you must
+append contents of file Far\7zToFar.ini to file
+..\Program Files\Far\Plugins\MultiArc\Formats\Custom.ini.
+
+
+If you want to cancel using 7-Zip by MultiArc, just remove lines that contain
+7-Zip (7z) program name from HKEY_LOCAL_MACHINE\SOFTWARE\Far\Plugins\MultiArc\ZIP
+registry key.

+
+Source code of binaries can be found at:
+  http://www.7-zip.org/
+
+This package contains the following files:
+
+7za.exe     - standalone console version of 7-Zip with reduced formats support.
+7za.dll     - library for working with 7z archives
+7zxa.dll    - library for extracting from 7z archives

+  Windows 2000 / 2003 / 2008 / XP / Vista / 7 / 8 / 10
+  and  in any Windows x64 version with WoW64 support.
+All x64 binaries can work in any Windows x64 version. 
+
+All binaries use msvcrt.dll.
+
+7za.exe 
+-------
+
+7za.exe - is a standalone console version of 7-Zip with reduced formats support.
+
+  Extra: 7za.exe             : support for only some formats of 7-Zip.
+  7-Zip: 7z.exe with 7z.dll  : support for all formats of 7-Zip.
+
+7za.exe and 7z.exe from 7-Zip have same command line interface.
+7za.exe doesn't use external DLL files.
+
+You can read Help File (7-zip.chm) from 7-Zip package for description 
+of all commands and switches for 7za.exe and 7z.exe.
+
+7za.exe features:
+
+  - High compression ratio in 7z format
+  - Supported formats:
+      - Packing / unpacking: 7z, xz, ZIP, GZIP, BZIP2 and TAR 
+      - Unpacking only: Z, lzma, CAB.
+  - Highest compression ratio for ZIP and GZIP formats.
+  - Fast compression and decompression
+  - Strong AES-256 encryption in 7z and ZIP formats.
+
+Note: LZMA SDK contains 7zr.exe - more reduced version of 7za.exe.
+But you can use 7zr.exe as "public domain" code.
+
+
+
+DLL files
+---------
+
+7za.dll and 7zxa.dll are reduced versions of 7z.dll from 7-Zip.
+7za.dll and 7zxa.dll support only 7z format.
+Note: 7z.dll is main DLL file that works with all archive types in 7-Zip.
+
+7za.dll and 7zxa.dll support the following decoding methods:
+    - LZMA, LZMA2, PPMD, BCJ, BCJ2, COPY, 7zAES, BZip2, Deflate.
+
+7za.dll also supports 7z encoding with the following encoding methods:
+    - LZMA, LZMA2, PPMD, BCJ, BCJ2, COPY, 7zAES.
+
+7za.dll and 7zxa.dll work via COM interfaces.
+But these DLLs don't use standard COM interfaces for objects creating.
+
+Look also example code that calls DLL functions (in source code of 7-Zip):
+ 
+ 7zip\UI\Client7z
+
+Another example of binary that uses these interface is 7-Zip itself.
+The following binaries from 7-Zip use 7z.dll:
+  - 7z.exe (console version)
+  - 7zG.exe (GUI version)
+  - 7zFM.exe (7-Zip File Manager)
+
+Note: The source code of LZMA SDK also contains the code for similar DLLs
+(DLLs without BZip2, Deflate support). And these files from LZMA SDK can be 
+used as "public domain" code. If you use LZMA SDK files, you don't need to 
+follow GNU LGPL rules, if you want to change the code.
+
+
+
+
+License FAQ
+-----------
+
+Can I use the EXE or DLL files from 7-Zip in a commercial application?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Yes, but you are required to specify in documentation for your application:
+  (1) that you used parts of the 7-Zip program, 
+  (2) that 7-Zip is licensed under the GNU LGPL license and 
+  (3) you must give a link to www.7-zip.org, where the source code can be found.
+
+
+Can I use the source code of 7-Zip in a commercial application?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Since 7-Zip is licensed under the GNU LGPL you must follow the rules of that license. 
+In brief, it means that any LGPL'ed code must remain licensed under the LGPL. 
+For instance, you can change the code from 7-Zip or write a wrapper for some 
+code from 7-Zip and compile it into a DLL; but, the source code of that DLL 
+(including your modifications / additions / wrapper) must be licensed under 
+the LGPL or GPL. 
+Any other code in your application can be licensed as you wish. This scheme allows 
+users and developers to change LGPL'ed code and recompile that DLL. That is the 
+idea of free software. Read more here: http://www.gnu.org/. 
+
+
+
+Note: You can look also LZMA SDK, which is available under a more liberal license.
