+# UNIX FOR ARTISTS
+### Fun with FFMPEG
+
+## Requirements
+
+The following applications and runtime environments are needed to run the scripts used in the workshop.
+Installation instructions are available below, broken down by operating system.
+
+* [Bash](https://www.gnu.org/software/bash/) - *You probably have it already!*
+* [FFMPEG](https://www.ffmpeg.org/)
+* [ImageMagick](https://imagemagick.org/index.php)
+* [Youtube-dl](https://ytdl-org.github.io/youtube-dl/index.html)
+* [Golang](https://golang.org/)
+* \*[Python3](https://www.python.org/downloads/) (*optional*)
+* \*[Node.js](https://nodejs.org/en/) (*optional*)
+
+It's very helpful to have a text editor that you can comfortably read and edit scripts in.
+This selection of text editors ranges from free and open source to "free to use" and "free to try".
+You can also use TextEdit or Notepad or any text editing application you prefer as long as it's capable of editing in plaintext.
+
+* [Atom](https://atom.io/) - Free. *macOS, Windows and Linux.*
+* [GNU Emacs](https://www.gnu.org/software/emacs/download.html) - Free. *Linux, macOS and Windows.*
+* [Visual Studio Code](https://code.visualstudio.com/download) - Free. *macOS, Windows and Linux.*
+* [Sublime Text 3](https://www.sublimetext.com/3) - Free to evaluate. *macOS, Windows and Linux.*
+* [Notepad++](https://notepad-plus-plus.org/downloads/) - Free to use. *Windows only.*
+* [BBEdit](http://www.barebones.com/products/bbedit/download.html) - Freemium. *macOS only.*
+
+-------
+
+## macOS
+
+![The macOS Terminal](img/mac_terminal.png "The macOS Terminal")
+
+Open the Terminal app located in your Applications folder.
+Bash 3.2 is available by default on macOS.
+
+
+##### Install Homebrew
+
+Go to [https://brew.sh](https://brew.sh) and run the command under the "Install Homebrew" heading after pasting it into your Terminal.
+
+You will be asked to confirm a few things while Homebrew installs.
+
+Once the installation process is complete you can install the applications we will be using in this workshop by running the following commands:
+
+```bash
+brew install ffmpeg imagemagick youtube-dl
+```
+
+Optionally, you can install Node.js for a single example that we will be covering in the workshop.
+
+```bash
+brew install node
+```
+
+Make sure that you have a compatible version of Python installed by running the following command: 
+
+```bash
+python3 --version
+```
+
+It should print out a value similar to `Python 3.8.2`. 
+Anything higher than 3.7.0 will work.
+
+##### Install Golang on macOS
+
+Go to the [Golang download site](https://golang.org/doc/install).
+
+Select the "Mac" tab under "2. Go install." if not already selected and download the .pkg installer using the "Download Go for Mac" button.
+
+Open the installer and follow the instructions.
+
+Confirm that Go is installed by running the following command in Terminal:
+
+```bash
+go version
+```
+
+If Golang has been installed correctly you can now install `primitive`.
+
+```bash
+go get -u github.com/fogleman/primitive
+```
+
+-------
+
+## Windows 10
+ 
+Windows has its own command-line interpreter, but in order to keep code and examples consistent across different operating systems you will need to install the Windows Subsystem for Linux (WSL).
+
+##### Enable WSL
+
+Open the "Turn Windows Features on or off" dialog by searching in your command bar.
+
+![Turn Windows features on or off](img/windows_10_turn_windows_features.png "Turn Windows features on or off")
+
+Enable "Virtual Machine Platform" and "Windows Subsystem for Linux" by selecting the checkboxes next to the items and hit "OK".
+
+![Enable WSL and Virtual Machine Platform](img/windows_10_enable.png "Enable WSL and Virtual Machine Platform")
+
+Restart your computer for changes to apply.
+
+
+##### Install Ubuntu 20.04 LTS
+
+Open the Microsoft Store and search for "Ubuntu".
+For the latest LTS version, install `Ubuntu 20.04`.
+
+![Install Ubuntu 20.04](img/windows_10_install.png "Install Ubuntu 20.04 through the Microsoft Store")
+
+Other versions of Ubuntu or openSUSE may work, but will be subject to differences in behavior.
+
+![Select the Ubuntu shell](img/windows_10_ubuntu.png "Select the Ubuntu shell")
+
+Once you've installed Ubuntu, you can open the shell and begin running commands using Bash.
+
+
+##### Install Requirements on Windows 10
+
+![The Ubuntu shell on Windows 10](img/windows_10_terminal.png "The Ubuntu shell on Windows 10")
+
+You can now run the following commands to install the applications for this workshop:
+
+```bash
+sudo apt update
+sudo apt install -y ffmpeg imagemagick youtube-dl
+```
+
+Optionally install Node.js.
+
+```bash
+sudo apt install -y nodejs npm
+```
+
+
+##### Install Golang on Windows 10
+
+Go to the [Golang download site](https://golang.org/doc/install).
+
+Select the "Windows" tab under "2. Go install." if not already selected and download the .msi installer by using the "Download Go for Windows" button.
+
+Confirm that Go is installed by running the following command in your shell:
+
+```bash
+go version
+```
+
+If Golang has been installed correctly you can now install `primitive`.
+
+```bash
+go get -u github.com/fogleman/primitive
+```
+
+-------
+
+Additional tutorials for installing Bash on Windows 10.
+
+* [How to Install Linux Bash Shell on Windows 10](https://itsfoss.com/install-bash-on-windows/)
+* [Install Bash on Windows 10](https://bayton.org/docs/linux/ubuntu/install-bash-on-windows-10-build-14316/)
+
+-------
+
+## Linux
+
+Open up your preferred terminal application and install the required applications on a Debian-based system.
+
+```bash
+sudo apt install -y ffmpeg imagemagick youtube-dl
+```
+
+Or, if your distribution uses the `yum` package manager.
+
+```bash
+yum install ffmpeg imagemagick youtube-dl
+```
+
+Optionally install Node.js.
+
+```bash
+sudo apt install -y nodejs npm
+```
+Or using yum.
+
+```
+yum install nodejs
+```
+
+##### Install Golang on Linux
+
+Go to the [Golang download site](https://golang.org/doc/install).
+
+Select the "Linux" tab under "2. Go install." if not already selected and download the .tar.gz archive using the "Download Go for Linux" button.
+
+Navigate to the folder you downloaded the archive into.
+For the following commands, `go1.16.3.linux-amd64.tar.gz` can be replaced by the filename of the version that you just downloaded.
+
+```bash
+sudo rm -rf /usr/local/go
+sudo tar -C /usr/local -xzf go1.16.3.linux-amd64.tar.gz
+export PATH=$PATH:/usr/local/go/bin
+```
+
+Either restart your terminal or run the command `source $HOME/.profile` to apply the changes just made to your system.
+
+Confirm that Go is installed by running the following command:
+
+```bash
+go version
+```
+
+If Golang has been correctly installed you can now install `primitive`.
+
+```bash
+go get -u github.com/fogleman/primitive
+```

+#
+# First, install ffmpeg and youtube-dl
+#
+# https://ffmpeg.org/download.html
+# https://ytdl-org.github.io/youtube-dl/download.html
+#
+# To capture a stream at https://yoururl and save to a dated, named TS file:
+#
+# bash capture.sh https://yoururl streamfilename
+#
+# Will create file streamfile_STARTDATE.ts and streamfilename.txt containing stream metadata.
+#
+# To capture stream and convert to an MKV file after:
+#
+# bash capture.sh https://streamurl streamfilename "convert"
+#
+# Will create TS file and streamfile_STARTDATE_to_FINISHDATE.mkv after capture complete.
+#
+# Note: Since this is capturing from a M3U8 stream you may end up retrieving more of earlier
+#       parts of the stream than the metadata will indicate. This will depend on the service
+#       you are capturing from.
