 First, instantiate the srs struct with the provided algorithm, uid and db implementations:
 
-	// Algo
-	now := time.Now().UTC()
-	sm2 := sm2.New(now)
+```go
+// Algo
+now := time.Now().UTC()

-	// Db
-	opts := badger.DefaultOptions("./badger")
-	opts.Logger = nil

 After that, you can update and save card reviews of a given deck:
 
-	r = review.Review{}
-	r.DeckId = "somedeckid"
+```go
+r = review.Review{}
+r.DeckId = "somedeckid"
 
-	r.Items = []review.ReviewItem{
-		{CardId: 65, Quality: 1},
-		{CardId: 3, Quality: 5},
-		{CardId: 1, Quality: 0},
-	}
+r.Items = []review.ReviewItem{
+    {CardId: 65, Quality: 1},
+    {CardId: 3, Quality: 5},
+    {CardId: 1, Quality: 0},
+}
 
-	_, err = hdl.Update(r)
-	if err != nil {
-		fatal(err)
-	}
+_, err = hdl.Update(r)
+if err != nil {
+    fatal(err)
+}
+```
 
 
 And retrieve cards that are due for review
 
-	tdue := time.Now().UTC()
-	dueCards, _ := hdl.Due(res.DeckId, tdue)
+```go
+tdue := time.Now().UTC()
+dueCards, _ := hdl.Due(res.DeckId, tdue)
+```
