+### Typed document operations
+
+In `v2.0.0`+, the client allows you to define a document struct to be used type for some of the document operations.

+To do that, you've to use `typesense.GenericCollection`:

+```go
+type companyDocument struct {
+    ID           string `json:"id"`
+    CompanyName  string `json:"company_name"`
+    NumEmployees int    `json:"num_employees"`
+    Country      string `json:"country"`

+doc, err := typesense.GenericCollection[*companyDocument](typesenseClient, collectionName).Document("123").Retrieve(context.Background())
+```
