+## Install
+
+```sh
+make deps
+```
+
+## Examples
+
+```go
+import "github.com/ipfs/go-cid"
+
+// Create a cid from a marshaled string
+c, err := cid.Decode("zdvgqEMYmNeH5fKciougvQcfzMcNjF3Z1tPouJ8C7pc3pe63k")
+if err != nil {...}
+
+fmt.Println(c)
+
+// Create a cid manually by specifying the 'prefix' parameters
+pref := cid.Prefix{
+	Version: 1,
+	Codec: cid.Raw,
+	MhType: mh.SHA2_256,
+	MhLength: -1, // default length
+}
+
+// And then feed it some data
+c, err := pref.Sum([]byte("Hello World!"))
+if err != nil {...}
+
+fmt.Println(c)
+
+// To test if two cid's are equivalent, be sure to use the 'Equals' method:
+if c1.Equals(c2) {
+	fmt.Println("These two refer to the same exact data!")
+}
+
+// To check if some data matches a given cid, check the prefix sum:
+other, err := c.Prefix().Sum(mydata)
+if err != nil {...}
+
+if !c.Equals(other) {
+	fmt.Println("This data is different.")
+}
+
+```
