+> Attention: This is still alpha, so some things won't work, not all things are inplemented.
+I (Phil from Lossless) expect this to be ready 2016/05/01.
 
 ## Usage
 
 ```javascript
 var smartssh = require("smartssh");
-var sshInstance = new smartssh({
+var sshInstance = new smartssh.sshInstance({
     sshDir: "/some/path/.ssh", // the standard ssh directory, optional, defaults to "~./.ssh"
     sshSync: true // sync ssh this instance will represent the status of an ssh dir if set to true;
 });
 
-sshInstance.addKey({
+sshInstance.addKey(new smartssh.sshKey({ 
     private: "somestring",
-    public: "somestring"
+    public: "somestring", // optional
+    for:"github.com",
+    encoding: "base64" // optional, defaults to "utf8", can be "utf8" or "base64", useful for reading ssh keys from environment variables
+}));
+
+sshInstance.createKey({
+    for:"gitlab.com" // returns new key in the form sshKey, read more about the sshKey class below
+})
+
+sshInstance.getKey({ // returns ssh key in the form sshKey, read more about the sshKey class below
+    for:"github.com"
 });
 
+sshInstance.getKeys() // returns array of all available getKeys. Each key is in form of class sshKey
+
