+## Overview
+
+While probably not the most useful as such, this example demonstrates the ability of the ComfyLab XY Plot to handle various resolutions or aspect ratios within the same grid.
+
+Here we generate images of various resolutions, and apply rotations.
+
+## Workflow
+
+**Load either `various resolutions.json` or `various resolutions.png` into ComfyUI.**\
+Adjust the checkpoint to one available in your ComfyUI instance.\
+Execute the workflow.
+
+![result](./images/result.jpg)
+
+What we did:
+
+- included the ComfyLab `Resolution to Dimensions` node, to split the first input (`1024 x 1024`, ...) into width and height, piped into `Empty Latent Image`
+  - we could have done this differently, I chose this method as it is straightforward in this case
+- we also used a 2nd input list to set rotations, piped into the `rotation` input of `Rotate Latent`
+  - remember, we can do that because the `Queue` outputs are of type Any

-# Tutorials / XY Plot: 3 - advanced techniques
-
-Welcome to this third (and last) tutorial of the XY Plot series!
-
-Here we are going to see a few advanced techniques you may find useful.\
-Of course, I cannot anticipate all the use cases, but by following this tutorial, I hope you will see the versatility of the ComfyLab XY Plot nodes, and understand how to adapt for your scenario.\
-Here, no frills, we'll go straight to the point, to focus of the functionalities rather than fancy grid customization.
-
-> [!IMPORTANT]
-> If you haven't yet, it is recommended to follow (at least read) the first 2 tutorials ([1](../1%20-%20the%20basics/) & [2](../2%20-%20pimp%20my%20grid/)), and read the [XY Plot core concepts](../../../node%20reference/xy%20plot/0%20-%20core%20concepts.md).\
-> You will probably need them in this advanced tutorial.
-
-Tutorial sections:
-
-- [Part 1 - Various checkpoints (or LoRAs, ...)](#part-1---various-checkpoints-or-loras-)
-- [Part 2 - Various resolutions and aspect ratios](#part-2---various-resolutions-and-aspect-ratios)
-- [Part 3 - Using the Output Config node](#part-3---using-the-output-config-node)
-- [TL;DR / Conclusion](#tldr--conclusion)
-
-> [!TIP]
-> As for all nodes in this extension, you can get useful contextual information, by just **moving the mouse pointer over a node or its inputs / widgets / outputs**. This should help you understand some details, without reading the more detailed wiki pages (yet).
-
-And as always, if you do not want to follow all the steps, you can jump directly to [the conclusion](#tldr--conclusion).
-
----
-
-## Part 1 - Various checkpoints (or LoRAs, ...)
-
-**Load either `workflow - part 1.json` or `workflow - part 1.png` into ComfyUI.**\
-**Important:**
-
-- in the first input list, adjust to checkpoints that are available in your ComfyUI instance
-- do no add the `.safetensors` extension, it will be added automatically
-
-Execute the workflow.
-
-![result - part 1](./details/result%20-%20part%201.jpg)
-
-Here we build a grid with 2 different checkpoints, vs a list of predefined seeds.
-
-What should be noticed:
-
-<ins>Checkpoints:</ins>
-
-- we have chosen not to include the `.safetensors` extension in the input
-  - it would have been displayed in the row headers, making them too long
-- instead, we have used a `Format: String` node, to append `.safetensors` to the `dim1 value` output of the `Queue` node
-- but by simply doing so, we cannot pipe the text output to the `Load Checkpoint` node, why?
-  - the `chkpt_name` widget does not accept any string, but a string that exists in the list
-- so to bypass this limitation we simply convert the text output to Any, thanks to the `Convert to Any` node
-  - ![Any output](./details/detail%20-%20part%201%20-%20any.jpg)
-
-> [!NOTE]
-> You can read more about the Any output in the [XY Plot core concepts](../../../node%20reference/xy%20plot/0%20-%20core%20concepts.md), and the [2nd tutorial of the `Output Config` node](../../Output%20Config/2%20-%20more%20options)
-
-<ins>Seeds:</ins>
-
-- theoritically, we should have converted the list values to integers, thanks to the `convert` combo widget
-  - but it also works (for seeds only AFAIK)
-
-### Lessons learned
-
-- combo widgets (as `chkpt_name` in `Load Checkpoint`) do not accept simple strings
-  - a workaround is to use an output with type Any (`"*"`)
-    - should we have included the `.safetensors` in the first input, we could have dropped the `Format: String` and `Convert to Any` node, because the type of `Queue` outputs is Any
-      - but this wouldn't be great in terms of display in the grid
-- the checkpoint list is connected to `dim1`, not `dim2`, for a performance reason
-  - if you want: just switch dim1 / dim2 and check the processing time _(more in the [core concepts page](../../../node%20reference/xy%20plot/0%20-%20core%20concepts.md))_
-
-> [!TIP]
-> You can basically use this approach for any combo widget, in particular when loading models (LoRA, ...).\
-> But be **very cautious** about the values you set in input: by using the Any type, we bypass the standard ComfyUI type checks, so the workflow may fail if the values are incorrect.
-
-### Variant: Random seeds
-
-Instead of fixed seeds, if you prefer to have a new random set of seeds each time you generate the grid, just replace the `List: ftom Multiline` node with `List: Random Seeds`.
-
-## Part 2 - Various resolutions and aspect ratios
-
-**Load either `workflow - part 2.json` or `workflow - part 2.png` into ComfyUI.**\
-Adjust the checkpoint to one available in your ComfyUI instance.\
-Execute the workflow.
-
-![result - part 2](./details/result%20-%20part%202.jpg)
-
-What we did:
-
-- include the ComfyLab `Resolution to Dimensions` node, to split the first input (`1024 x 1024`, ...) into width and height, piped into `Empty Latent Image`
-  - we could have done this differently, I chose this method as it is straightforward in this case
-- we also used a 2nd input list to set rotations, piped into the `rotation` input of `Rotate Latent`
-  - remember, we can do that because the `Queue` outputs are of type Any
-
-While probably not the most useful as such, this example demonstrates **the ability of the ComfyLab XY Plot to handle various resolutions or aspect ratios within the same grid**.
-
-## Part 3 - Using the Output Config node
-
-Here the workflow is similar to [Part1](#part-1---various-checkpoints-or-loras-), except that we use the `Output Config` node, to simplify and standardize our workflow.
-
-**Load either `workflow - part 3.json` or `workflow - part 3.png` into ComfyUI.**\
-**Copy one of the `output config - part 3.*` file, adjust the checkpoints to your env, and load it into the `Output Config` node.**
-
-- you should get outputs like this (more than the 4 displayed here):
-- ![outputs](./details/detail%20-%20part%203%20-%20output%20config.jpg)
-
-Execute the workflow.
-
-![result - part 3](./details/result%20-%20part%201.jpg)
-
-As expected, we have strictly the same results as in [Part 1](#part-1---various-checkpoints-or-loras-).
-
-What should be noticed:
-
-- the output config file is available in 3 different formats: JSON, JSON5 and YAML
-- we replaced the input lists by a single `Output Config` node
-  - we also added more outputs to the config file: CFG, steps, sampler, ... quite a lot indeed
-  - of course, we could have used 2 different `Output Config` nodes, one for the XY Plot itself, and another one for the other values: it's up to you to define how you want to standardize your configs
-- note how the `Output Config` node auto-detects the type from output values:
-  - for example, `cfg` is written without quotes, so it's detected as a string
-  - but for more combo widgets (sampler, scheduler), we have to force type to be Any (`*`)
-
-> [!TIP]
-> We won't go into details here about the configuration file itself, but you can find more information in the corresponding [node reference](../../../node%20reference/output%20config.md) and the [dedicated tutorials](../../../tutorials/Output%20Config/).
-
-## TL;DR / Conclusion
-
-In this tutorial, we have:
-
-- seen how to handle various checkpoints (or virtually any sort of model)
-  - and optimized the grid display at the same time
-- demonstrated the ability of the XY Plot to include images or various dimensions / apect ratios within the same grid
-- shown how we can use the `Output Config` node, to keep a collection of configs, while standardizing our workflow
-
-This tutorial is still in construction, so I will certainly add most techniques in the future, be sure to check.
-
-Also, you will find [various examples](../../../examples/) in the wiki (with less explanations).
-
-In the meantime, if you have any suggestion, feel free to open [a discussion](https://github.com/bugltd/ComfyLab-Pack/discussions).

+# Tutorials / XY Plot: 3 - Complex variations
+
+Welcome to this third tutorial of the XY Plot series!
+
+Here we are going to see a few advanced techniques, to make virtually anything vary, for example models or any value in a combo widget.\
+To achieve that, we will use 3 different methods:
+
+- simple: with dedicated nodes, for checkpoints / LoRAs / samplers / schedulers
+- versatile: adaptable to any kind of model (or combo widget)
+- with the [`Output Config`](../../Output%20Config/) node: to standardize your workflow, and keep parameters separated
+
+Each of these approaches will generate the same results: depending on your specifity, pick the one that matches your specific needs.
+
+> [!TIP]
+> In the following, we vary checkpoints vs a fixed list of seeds.
+> If you prefer to have a new set of **random seeds** each time you generate the grid, just replace the corresponding `List: ftom Multiline` node with `List: Random Seeds`.
+
+Tutorial sections:

+- [Part 1 - Simple: with a dedicated node (for checkpoints, LoRAs, samplers, schedulers)](#part-1---simple-with-a-dedicated-node-for-checkpoints-loras-samplers-schedulers)
+- [Part 2 - Versatile: any model (or combo widget)](#part-2---versatile-any-model-or-combo-widget)
+- [Part 3 - With the `Output Config` node](#part-3---with-the-output-config-node)
+- [TL;DR / Conclusion](#tldr--conclusion)
+
+And as always, if you do not want to follow all the steps, you can jump directly to [the conclusion](#tldr--conclusion).
+
+---
+
+## Expected results
+
+If you use the exact same parameters:
+
+- checkpoints: `sd_xl_base_1.0`, `Juggernaut-XI-byRunDiffusion`
+- seeds: `156680208700286`, `715168739510668`, `568208062071311`
+
+You should get the same result:\
+![result grid](./details/result%20.jpg)
+
+## Part 1 - Simple: with a dedicated node (for checkpoints, LoRAs, samplers, schedulers)
+
+> [!TIP]
+> Here we use the `List: Checkpoints` node, that allows to select any number of checkpoints (from your ComfyUI `models/checkpoints` folder), and get a list of file names.\
+> Similar nodes exist for: LoRAs, samplers, schedulers.
+
+**Load either `workflow - part 1.json` or `workflow - part 1.png` into ComfyUI.**\
+**Important:**
+
+- in the `List: Checkpoints` node, select a few checkpoints from your env
+  - in the example, I use SDXL 1.0 and Juggernaut XL v11
+- ensure the widget `with file extension?` is unchecked, as we will add the extension later
+
+Execute the workflow.
+
+### What should be noticed
+
+> [!NOTE]
+> we have chosen to not include the `.safetensors` extension in the input: it would have been displayed in the row headers, making them too long. Of course, you can keep it, and skip the following.
+
+To append the `.safetensors` extension:
+
+- we use a `Format: String` node, to add the extension to the `dim1 value` output of the `Queue` node
+- but by simply doing so, we cannot pipe the text output to the `Load Checkpoint` node, why?
+  - the `chkpt_name` widget does not accept any string, but a string that exists in the list
+- so to bypass this limitation we simply convert the text output to Any, thanks to the `Convert to Any` node
+  - ![Any output](./details/detail%20-%20part%201-%20any.jpg)
+
+> [!NOTE]
+> You can read more about the Any output in the [XY Plot core concepts](../../../node%20reference/xy%20plot/0%20-%20core%20concepts.md), and the [2nd tutorial of the `Output Config` node](../../Output%20Config/2%20-%20more%20options/)
+
+### Lessons learned
+
+- combo widgets (as `chkpt_name` in `Load Checkpoint`) do not accept simple strings
+  - a workaround is to use an output with type Any (`"*"`)
+    - should we have included the `.safetensors` in the first input, we could have dropped the `Format: String` and `Convert to Any` nodes, because the `XY Plot: Queue` outputs are themselves of type Any
+    - but this wouldn't be great in terms of display in the grid
+- the checkpoint list is connected to `dim1`, not `dim2`, for a performance reason
+  - for the test: just switch dim1 / dim2 and check the processing time _(more in the [core concepts page](../../../node%20reference/xy%20plot/0%20-%20core%20concepts.md))_
+
+## Part 2 - Versatile: any model (or combo widget)
+
+While it is usually simpler to use the `List` nodes dedicated to checkpoints / LoRAs / samplers / schedulers, there are some cases where we need to use a more versatile approach:
+
+- we want to vary another type of model / value from a combo widget
+- we have stored the list as a separate text file (e.g. test case), and prefer to re-use it, rather than manually selecting the values
+
+This short part will cover exactly that, to show how you can adapt the XY Plot to many specific cases.
+
+**Load either `workflow - part 2.json` or `workflow - part 2.png` into ComfyUI.**\
+**Important:**
+
+- in the first input list, adjust to checkpoints that are available in your ComfyUI instance
+- do no add the `.safetensors` extension, it will be added automatically
+
+Execute the workflow.
+
+### Lessons learned
+
+By using a `List: String` or `List: Multiline`, we can basically send any value, as long as we ensure it matches the destinastion widget.\
+You can use this approach for any combo widget, in particular when loading models, or any value in a combo widget.
+
+> [!IMPORTANT]
+> Be **very cautious** about the values you set in input: by using the Any type, we bypass the standard ComfyUI type checks, so the workflow may fail if the values are incorrect.
+
+## Part 3 - With the `Output Config` node
+
+Here we use the ComfyLab [`Output Config`](../../../node%20reference/output%20config.md) node, to keep our workflow and values separated.
+
+**Load either `workflow - part 3.json` or `workflow - part 3.png` into ComfyUI.**\
+**Copy one of the `output config - part 3.*` files, adjust the checkpoints to your env, and load it into the `Output Config` node.**
+
+- you should get outputs like this (more than the 4 displayed here):
+- ![outputs](./details/detail%20-%20part%203%20-%20output%20config.jpg)
+
+Execute the workflow.
+
+As expected, we have strictly the same results as in [Part1](#part-1---simple-with-a-dedicated-node-for-checkpoints-loras-samplers-schedulers) and [Part 2](#part-2---versatile-any-model-or-combo-widget).
+
+### What should be noticed
+
+- the output config file is available in 3 different formats: JSON, JSON5 and YAML
+- we have replaced the input lists by a single `Output Config` node
+  - we've also added more outputs to the config file: CFG, steps, sampler, ... quite a lot indeed
+  - of course, we could have used 2 different `Output Config` nodes, one for the XY Plot itself, and another one for the other values: it's up to you to define how you want to standardize your configs
+- note how the `Output Config` node auto-detects the type from output values:
+  - for example, `cfg` is written without quotes, so it's detected as a float
+  - but for combo widgets (sampler, scheduler), we have to force type to be Any (`*`)
+
+> [!TIP]
+> We won't go into details here about the configuration file itself, but you can find more information in the corresponding [node reference](../../../node%20reference/output%20config.md) and the [dedicated tutorials](../../../tutorials/Output%20Config/).
+
+## TL;DR / Conclusion
+
+In this tutorial, we have covered 3 different methods to vary checkpoints (or many other things):
+
+- simple one, using a dedicated node: applicable to checkpoints, LoRAs, samplers, schedulers
+- a more versatile one, that should adapt to many of your use cases: use a `List: from String` or `List: from Multiline`
+- one using the `Output Config` node, to standardize your workflow and keep the values separated
+
+> [!TIP]
+> You can find [more examples](../../../examples/) in the wiki.

-- various checkpoints (or virtually any model, LoRA, ...)
-- integrate various image resolutions / aspect ratios in the grid
-- combine the XY Plot with the `Output Config` node
+- various checkpoints (or virtually any model, LoRA, ...), following 3 methods using:
+  - dedicated nodes to manually select a list of checkpoints / LoRAs / samplers / scheduler
+  - a more versatile approach for vurtually anything (models, any combo value)
+  - the `Output Config` node to keep the use case data separated from your workflow
