 # upper.io/db
 
-Still a work in progress.
+[Upper DB][1] is a [Go][2] package for saving and retrieving [Go][2] structs
+to permanent storage with ease.
+
+[Upper DB][1] is able to comunicate with SQL and NoSQL databases through a
+simplified API and perform the most common operations on database systems such
+as appending, searching, updating and removing items.
+
+## Database compatibility
+
+Wrappers are provided for the following databases:
+
+* SQLite3
+* MySQL
+* PostgreSQL
+* MongoDB
+
+Wrappers are based on popular SQL drivers for `database/sql` and in the MongoDB
+driver `labix.org/v2/mgo`.
+
+## Installation
+
+Get the main package.
+
+```
+go get upper.io/db
+```
+
+Then, get the wrapper you want to use. Choose one of `mysql`, `sqlite`, `mongo`
+or `postgresql`.
+
+```
+go get upper.io/db/sqlite
+```
+
+## An actual code example
+
+Define a Go struct, use Go datatypes and define column names within field tags.
+
+```
+type Birthday struct {
+	Name string    `field:"name"`
+	Born time.Time `field:"born"`
+}
+```
+
+Define your database settings.
+
+```
+var settings = db.Settings{
+	Database: `example.db`,
+}
+```
+
+Open a connection to a database using a driver (`sqlite` in this example).
+
+```
+sess, err = db.Open("sqlite", settings)
+```
+
+Get a collection reference.
+
+```
+ birthdayCollection, err = sess.Collection("birthdays")
+```
+
+Use the `Collection.Append` method to insert some data into the collection.
+
+```
+birthdayCollection.Append(Birthday{
+  Name: "Hayao Miyazaki",
+  Born: time.Date(1941, time.January, 5, 0, 0, 0, 0, time.UTC),
+})
+```
+
+Use the `Collection.Filter` method without arguments to retrieve all the rows
+within the collection.
+
+```
+res, err = birthdayCollection.Filter()
+
+var birthday Birthday
+
+for {
+  err = res.Next(&birthday)
+  if err == nil {
+    fmt.Printf("%s was born in %s.\n", birthday.Name, birthday.Born.Format("January 2, 2006"))
+  } else if err == db.ErrNoMoreRows {
+    break
+  } else {
+    panic(err.Error())
+  }
+}
+```
+
+Close this session, you can also use `defer` for closing.
+
+```
+sess.Close()
+```
