+## Adding a new tag mapping
+
+To add a new tag mapping, edit [src/tags.ts](src/tags.ts)
+
+Add your new tag to the `inferenceTags` array, like so:
+
+```typescript
+{
+    type: 'tag-filter',
+    task: 'text-to-image',
+    tags: ['flux', 'lora'],
+    providerModel: 'black-forest-labs/flux-dev-lora',
+    adapterType: 'lora',
+    status: 'live',
+}
+```
+
+Tag mappings allow you to map multiple Hugging Face models to a single Replicate model based on their tags. This is useful when you have a single Replicate model that can handle multiple variations of a model (like different LoRA adapters).
+
 ## Updating model mappings
 
 This repo uses a [GitHub Actions workflow](.github/workflows/sync.yml) to keep the model mappings up to date, as well as model warm/cold states.
