 # unRAID Walkthrough
+This article will walk you through getting Plex-Meta-Manager [PMM] set up and running via Docker.  It will cover:
+
+1. Installing Plex Meta Manager unRAID app
+2. Retrieving the image
+3. Setting up the initial config file
+4. Setting up a metadata file and creating a couple sample collections
+5. Creating a docker container that will keep running in the background
+
+The specific steps you will be taking:
+1. Verify that Plex Meta Manager unRAID app is installed and install it if not
+2. Use `unRAID APPS` to retrieve the PMM Docker image
+3. Create a directory for your config files and learn how to tell app to use it
+4. Gather two things that the script requires:
+   1. TMDb API Key
+   2. Plex URL and Token
+5. Then, iteratively:
+   1. use `unRAID >_Console` to run the commmands
+   2. use a text editor to modify a couple of text files until you have a working config file and a single working metadata file.
+
+If the idea of editing YAML files by hand is daunting, this may not be the tool for you.  All the configuration of PMM is done via YAML text files, so if you are unable or unwilling to learn how those work, you should stop here.
+
+Finally, this walkthrough is intended to give you a basic grounding in how to get the script running.  It doesn't cover how to create your own collections, or how to add overlays, or any of the myriad other things PMM is capable of.  It provides a simple "Getting Started" guide for those for whom the standard install instructions make no sense; presumably because you've never run a unRAID app (Docker container) before.
+
+
+## Prerequisites.
+
+Anywhere you see
+
+```
+something like this
+```
+
+That’s a command you’re going to type or paste into your unRAID Plex Meta Manager `>_Console` terminal (Linux).
+
+**IMPORTANT NOTES:**
+
+* If you were not aware, the unRAID app store leverages Docker containers. As such, we are tweaking the existing Docker container walkthrough to make it work on unRAID. This walkthrough is going to be pretty pedantic.  I’m assuming you’re reading it because you have no idea how to get this going on unRAID, so I’m proceeding from the assumption that you want to be walked through every little detail.  You’re going to deliberately cause errors and then fix them as you go through it.  This is to help you understand what exactly is going on behind the scenes so that when you see these sorts of problems in the wild you will have some background to understand what’s happening.  If I only give you the happy path walkthrough, then when you make a typo later on you’ll have no idea where that typo might be or why it’s breaking things.
+
+* You may want to take an hour to get familiar with Docker fundamentals with the [official tutorial](https://www.docker.com/101-tutorial/).
+
+  * DO NOT MAKE ANY CHANGES BELOW if you want this to just work.  Don't change the docker image. `linuxserver.io` will not work for this, so don't change the paths, etc.
+
+### Prepare a small test library [optional]
+
+```{include} wt/wt-test-library.md
+```
+
+### Installing Community Applications in unRAID
 
 Thankfully, getting Plex Meta Manager working on unRAID is a fairly simple task. unRAID works mostly with docker containers, so the pre-built container available on docker hub works perfectly with a little configuration.
 To install a container from docker hub, you will need community applications - a very popular plugin for unRAID servers. If you don't already have this installed, you can install it [here](https://forums.unraid.net/topic/38582-plug-in-community-applications/)
 
-## Basic Installation
+### Installing Plex Meta Manager in unRAID
-
 1. Head to the `Apps` tab of unRAID (Community Applications), and search `plex meta manager` in the upper right search box. There will be a couple of results shown, but you should ignore them ([Why?](images)) and use the official image.
 
 2. Click the `Install` button on the Template from Sohjiro's Repository Tools.
 
 3. Choose which branch you want to run `latest`, `develop`, or `nightly`. 
 
-4. Click `Show more settings...` to set any [Environmental Variables](../../home/environmental) you wish to use. **None are required for PMM to work.**
+4. Click `Show more settings...` to set any [Environmental Variables](../../home/environmental) you wish to use. **For the purposes of this walkthrough, the** `Container Path: /config` **path for the unRAID app is** `/mnt/user/appdata/plex-meta-manager`
-
-   * For example if you wish to have the container perform a run immediately and then shut down set `Run Immediately (--run)` to `true`.
 
 5. Hit `Apply`, and allow unRAID to download the docker container.
 
-6. Navigate to the `Docker` tab in unRAID, and stop the `plex-meta-manager` container if it has auto-started.
+#### Important note on Docker images
+
+This tutorial uses the official image, and you should, too.  Don't change `meisnate12/plex-meta-manager` to the `linuxserver.io` image or any other. Other images may have [idiosyncracies](images.md) that will prevent this walkthrough from working.  The official image *will* behave exactly as documented below.  Others very possibly won't.
+
+The great thing about Docker is that all the setup you'd have to do to run PMM is already done inside the docker image.
+
+That means we can just jump right into running it.  Open a `Console` by left-clicking on the running Plex-Meta-Manager container and selecting `>_Console`. This will open up an interactive session within the container to be able to run the commands we want.
+
+```
+python plex_meta_manager.py --run
+```
+This is going to fail with an error. That's expected.
+
+You should see something like this:
+
+```
+Config Error: config not found at //config
+```
+This is going to fail with an error, which you will then fix.
+
+### Create a directory to quiet an error later
+
+The default config file contains a reference to a directory that will show an error in the output later.  That error can safely be ignored, but it causes some confusion with new users from time to time.
+
+We'll create it here so the error doesn't show up later.

+````{tab} Linux
+[type this into your terminal]
+```
+mkdir config/assets
+```
+````
+````{tab} OS X
+[type this into your terminal]
+```
+mkdir config/assets
+```
+````
+````{tab} Windows
+[type this into your terminal]
+```
+mkdir config\assets
+```
+````
+
+### Setting up the initial config file
+
+```{include} wt/wt-01-basic-config.md
+```
+
+#### Editing the config template
+
+First, make a copy of the template:
+
+````{tab} Linux
+Get a copy of the template to edit [type this into your terminal]:
+```
+curl -fLvo config/config.yml https://raw.githubusercontent.com/meisnate12/Plex-Meta-Manager/master/config/config.yml.template
+```
+````
+````{tab} OS X
+Get a copy of the template to edit [type this into your terminal]:
+```
+curl -fLvo config/config.yml https://raw.githubusercontent.com/meisnate12/Plex-Meta-Manager/master/config/config.yml.template
+```
+````
+````{tab} Windows
+Go to [this URL](https://raw.githubusercontent.com/meisnate12/Plex-Meta-Manager/master/config/config.yml.template) using a web browser; choose the "Save" command, then save the file at:
+```
+C:\Users\YOURUSERNAME\plex-meta-manager\config\config.yml
+```
+````
+Now open the copy in an editor on the machine of your choice(All 3 are fine. Just decide on one):
+
+```{include} wt/wt-editor.md
+```
+
+```{include} wt/wt-02-config-bad-library.md
+```
+
+#### Testing the config file
+
+Save the file:
+
+```{include} wt/wt-save.md
+```
+
+Then run the script again:
+
+```{include} wt/wt-run-shell.md
+```
+
+```{include} wt/wt-03-lib-err-and-fix.md
+```
+
+
+### Creating a few sample collections.
+
+```{include} wt/wt-04-default-intro.md
+```
+
+So let's run the script and see this happen:
+
+
+```{include} wt/wt-run-shell.md
+```
+
+```{include} wt/wt-04b-default-after.md
+```
+
+### Setting up a metadata file and creating a sample collection.
+
+```{include} wt/wt-05-local-file.md
+```
+
+Save the file:
+
+```{include} wt/wt-save.md
+```
+
+Then run the script again:
+
+```{include} wt/wt-run-shell.md
+```
+
+```{include} wt/wt-06-local-after.md
+```
+
+### Adding Overlays to movies.
+
+```{include} wt/wt-07-overlay-add.md
+```
+
+Save the file:
+
+```{include} wt/wt-save.md
+```
+
+Then run the script again:
+
+```{include} wt/wt-run-shell.md
+```
+
+```{include} wt/wt-08-overlay-after.md
+```
+
+```{include} wt/wt-09-next-steps.md
+```
+
+## Other Topics
 
-6. Create `config.yml` and `library.yml` files as-per the [documentation](../../config/configuration) in the Host Path you set (/mnt/user/appdata/plex-meta-manager by default)
+### Scheduling
 
-7. Once finished, run the container. Voila! Logs are located in `yourhostpath/logs`.
+```{include} wt/wt-10-scheduling.md
+```
+### I want to use the develop branch
 
-## Advanced Installation (Authenticating Trakt or MyAnimeList)
+Add the `develop` tag to the image name in your `Repository:` setting for the Plex Meta Manager unRAID app: [meisnate12/plex-meta-manager:develop]
 
-Due to how unRAID handles docker containers, it can be a little confusing at first to enable Trakt, MyAnimeList, and other sources. At this time, these sources require you to follow through to a URL, and provide a code or link to Plex Meta Manager. unRAID doesn't have a built-in way to interact with the terminals of docker containers, so a workaround must be used:
+```
+meisnate12/plex-meta-manager:develop
+                             ^^^^^^^
+```
 
-1. Stop the Plex Meta Manager docker container if it's currently running.
+This may not work if you are not using the official image; for example, it does not work with the lsio image.
 
-2. Follow the instructions for either [Trakt](../../config/trakt) or [MyAnimeList](../../config/myanimelist), and add the relevant values to your `config.yml`
+### I want to use the nightly branch
 
-3. Edit the `Time to Run` variable to reflect a time that is NOT the current time. We don't want the script to be running right now. Set `Run` to `false` if you've chosen to add that variable. Then, start the container.
+Add the `nightly` tag to the image name in your `Repository:` setting for the Plex Meta Manager unRAID app: [meisnate12/plex-meta-manager:nightly]
 
-4. Click the Terminal button in the upper right corner of the unRAID WebUI (`>_`)
+```
+meisnate12/plex-meta-manager:nightly
+                             ^^^^^^^
+```
 
-5. Run `docker exec -it plex-meta-manager /bin/bash`
+This may not work if you are not using the official image; for example, it does not work with the lsio image.
 
-   Note: this name is case-sensitive.  If this gives you an error like "Error: No such container: plex-meta-manager"; check the container config to see if you've named it something like "Plex-Meta-Manager",  If that's the case, change the name in the command to match your container.
+### I want to ensure I am using the master branch
 
-6. Run `ls` to make sure you're in the same directory as `plex_meta_manager.py`. If you don't see the script, run `cd /`
+Add the `latest` tag to the image name in your `Repository:` setting for the Plex Meta Manager unRAID app: [meisnate12/plex-meta-manager:latest]
 
-7. Run `python plex_meta_manager.py -r`, and watch as the script comes to life.
+```
+meisnate12/plex-meta-manager:latest
+                             ^^^^^^
+```
 
-8. You'll now notice, as per the [configuration documentation](../../config/configuration) on these sources, the script will ask you to click a URL and return an input. Go ahead and do so in this terminal window.
+This is the only version tag supplied by the lsio image.
 
-9. Once finished, and the script succeeds in connecting to your source, press `Ctrl + C` to cancel the script - and close out of the terminal window. Go ahead and stop the docker container, restore your container settings to your original preferences (restore `Time to Run`), and start the container.
