 ## Installation
 
-First you'll need to make sure your system has a c++ compiler.  For OSX, XCode will work, for Ubuntu, the build-essential package works.  You'll also need `git` if you want to track HEAD.
+First you'll need to make sure your system has a c++ compiler.  For OSX, XCode will work, for Ubuntu, the build-essential and libssl-dev packages work.
 
 To install create a folder somewhere in your filesystem with the "`nvm.sh`" file inside it.  I put mine in a folder called "`.nvm`".
 
 Or if you have `git` installed, then just clone it:
 
-    git clone git://gist.github.com/367305.git ~/.nvm
+    git clone git://github.com/creationix/nvm.git ~/.nvm
 
-Then add three lines to your bash profile:
+To activate nvm, you need to source it from your bash shell
 
-    NVM_DIR=$HOME/.nvm
-    . $NVM_DIR/nvm.sh
-    nvm use v0.1.91
+    . ~/.nvm/nvm.sh
 
-The first line tells your system where NVM is installed, you should already have nvm.sh there.  The second line loads the nvm function into your bash shell so that it's available as a command.  The third line sets your default node version.
+I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sources upon login.   
+Often I also put in a line to use a specific version of node.
     
 ## Usage
 
-To download, install, and use the v0.1.91 release of node do this:
+To download, compile, and install the v0.2.5 release of node, do this:
 
-    nvm install v0.1.91
+    nvm install v0.2.5
 
 And then in any new shell just use the installed version:
 
-    nvm use v0.1.91
-
-If you want to track HEAD then use the clone command:
-
-    nvm clone
-
-Then in any new shell you can get this version with:
-
-    nvm use HEAD
-
-When you want to grab the latest from the node repo do:
-
-    nvm update
+    nvm use v0.2.5
 
 If you want to see what versions you have installed issue:
 
-   nvm list
+    nvm ls
+
+To restore your PATH, you can deactivate it.
+
+    nvm deactivate
+
