 ## Usage
 
+### PostgreSQL
+
 Ensure a database is created and a table exists with `key` and `data` columns. For example, in PostgreSQL you can create a table with the following structure (replacing `table_name` with the name of the table the datastore will use - by default this is `blocks`):
 
 ```sql

 ds := sqlds.NewDatastore(mydb, queries)
 ```
 
+### SQLite
+
+The [SQLite](https://sqlite.org) wrapper tries to create the table automatically
+
+Prefix scans are optimized by using GLOB
+
+Import and use in your application:
+
+```go
+import (
+	"github.com/ipfs/go-ds-sql"
+	sqliteds "github.com/ipfs/go-ds-sql/sqlite"
+	_ "github.com/mattn/go-sqlite3"
+)
+
+func main() {
+	opts := &sqliteds.Options{
+		DSN: "db.sqlite"
+	}
+
+	ds, err := opts.Create()
+	if err != nil {
+		panic(err)
+	}
+}
+```
+
+If no `DSN` is specified, an unique in-memory database will be created
+
+### SQLCipher
+
+The SQLite wrapper also supports the [SQLCipher](https://www.zetetic.net/sqlcipher/) extension
+
+Import and use in your application:
+
+```go
+import (
+	"github.com/ipfs/go-ds-sql"
+	sqliteds "github.com/ipfs/go-ds-sql/sqlite"
+	_ "github.com/mutecomm/go-sqlcipher/v4"
+)
+
+func main() {
+	opts := &sqliteds.Options{
+		DSN: "encdb.sqlite"
+		Key: (byte[])("32_very_secure_bytes")
+	}
+
+	ds, err := opts.Create()
+	if err != nil {
+		panic(err)
+	}
+}
+```
