+
+## Usage
+
+Use any or all of the following tags to summon Arona: `arona, 1girl, white hairband, bow hairband, halo, short hair, single braid`
+- You can also add `blue eyes, two-tone hair, multicolored hair, blue hair, pink hair` if necessary.
+- `mechanical halo` can sometimes improve the quality of Arona's halo.
+- I tried tagging her different halo types (`heart halo`, `red halo`, etc.) but the AI doesn't recognize them very well.
+
+For her normal outfit: `school uniform, blue shirt, white sailor collar, long sleeves, white bowtie, white choker`
+- Images where her stomach was visible were tagged `midriff peek` or `midriff`.  The AI seems to like showing her this way by default, but you can prompt those tags to strengthen the effect (or negative prompt them to try to remove it).
+
+For her swimsuit outfit: `swimsuit, official alternate costume, black bikini, frills, frilled bikini`
+
+Arona frequently appears in the ruined classroom, which I have tried to tag consistently.  Use `ruined classroom, school desk, shallow water, cloud` to produce this background.
+
+Not all tags may be necessary.
+
+## Training
+*Exact parameters are provided in the accompanying JSON files.*
+- Trained on a set of 250 images.
+  - Datset included a mixture of SFW/NSFW
+  - 5 repeats
+  - 3 batch size, 4 epochs
+  - `(250 * 5) / 3 * 4` = 1667 steps
+- Initially tagged with WD1.4 convnextv2 model. Tags pruned/edited for consistency.
+- `constant_with_warmup` scheduler
+- 1.5e-5 text encoder LR
+- 1.5e-4 unet LR
+- 1e-5 optimizer LR
+- Used network_dimension 128 (same as usual) / network alpha 128 (default)
+- New: increased training resolution to 832x832.
+- Trained without VAE.
+- [Dataset can be found on the mega.co.nz repository.](https://mega.nz/folder/q6IyzAoB#xVogEUENCNG9D-C7mTftFQ)
+
+## Revisions
