    "**Make sure your images are captioned!**\n",
    "\n",
    "By default the name of your image files are assumed to be captions. If you want to get fancy, there are [more sophisticated techniques](https://github.com/victorchall/EveryDream2trainer/blob/main/doc/DATA.md)\n",

    "Training a small dataset like this is fast, and will give you a feel for how quickly your model (over-)trains depending on your training schedule, captioning schema, knob twiddling. This notebook provides some sensible defaults, there are more questions than answers in how best to fine tune anything. \n",

    "\n",
    "You may wish to consider adding \"sd1\" or \"sd2v\" or similar to remember what the base was, as you'll also have to tell your inference app what you were using, as its difficult for programs to know what inference YAML to use automatically. For instance, Automatic1111 webui requires you to copy the v2 inference YAML and rename it to match your checkpoint name so it knows how to load the file, tough it assumes SD 1.x compatible. Something to keep in mind if you start training on SD2.1.\n",

    "`max_epochs`, `sample_steps`, and `save_every_n_epochs` should be tuned to your dataset. I like to generate one or two sets of samples per save, and aim for 5 (give or take 2) saved checkpoints.\n",
