+## Installation
+
+Install:
+
+```shell
+go get -u github.com/go-redis/redis
+```
+
+Import:
+
+```go
+import "github.com/go-redis/redis"
+```
+
+## Quickstart
+
+```go
+func ExampleNewClient() {
+	client := redis.NewClient(&redis.Options{
+		Addr:     "localhost:6379",
+		Password: "", // no password set
+		DB:       0,  // use default DB
+	})
+
+	pong, err := client.Ping().Result()
+	fmt.Println(pong, err)
+	// Output: PONG <nil>
+}
+
+func ExampleClient() {
+	err := client.Set("key", "value", 0).Err()
+	if err != nil {
+		panic(err)
+	}
+
+	val, err := client.Get("key").Result()
+	if err != nil {
+		panic(err)
+	}
+	fmt.Println("key", val)
+
+	val2, err := client.Get("key2").Result()
+	if err == redis.Nil {
+		fmt.Println("key2 does not exists")
+	} else if err != nil {
+		panic(err)
+	} else {
+		fmt.Println("key2", val2)
+	}
+	// Output: key value
+	// key2 does not exists
+}
+```
+
+## Howto
+
+Please go through [examples](https://godoc.org/github.com/go-redis/redis#pkg-examples) to get an idea how to use this package.
+
+## Look and feel
+
+Some corner cases:
+
+    SET key value EX 10 NX
+    set, err := client.SetNX("key", "value", 10*time.Second).Result()
+
+    SORT list LIMIT 0 2 ASC
+    vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
+
+    ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
+    vals, err := client.ZRangeByScoreWithScores("zset", redis.ZRangeBy{
+        Min: "-inf",
+        Max: "+inf",
+        Offset: 0,
+        Count: 2,
+    }).Result()
+
+    ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
+    vals, err := client.ZInterStore("out", redis.ZStore{Weights: []int64{2, 3}}, "zset1", "zset2").Result()
+
+    EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
+    vals, err := client.Eval("return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
