+
+To getEvents use getEvents with a provider and any filters to filter the event
+
+```typescript
+const events = await getEvents({
+  creator,
+  about,
+  key,
+  value,
+  provider: new ethers.providers.JsonRpcProvider('http://localhost:8545'),
+  fromBlockOrBlockhash,

+})
+```
+
+Set key, about, creator, or value to `null` to not include that filter
