Heroku installation

　　It is the first time that I use heroku. But I encountered some problems
installing it. Luckily, I resolved the problem.(In windows 8)

Step 1: Sign up for an account

Step2: Download the heroku toolbelt

Step3: Open your command line tool and type in "heroku login"

　　Oops, errors pop up.

　　Sorry, I forget the error messages :(

　　But one thing can be sure: I could not login.

　　So I began to wonder whether I had installed the heroku in a correct
way...

I typed "heroku help" in the command line and saw many
options.

Then I tried "heroku regions".

It asked me to sign in. And I signed in successfully(But
I could not sign in when I typed "heroku login")

It asked me whether to generate a public key. choose yes
of course.

And I thought I had fixed the problem and typed "heroku
login"

Wow, I succeeded signing in!

Step4: git clone a project from remote server. (I used heroku not because I
wanted to create a new app, but because I had to modify an existing app)

　　Error happened again.

It says that I have no permission to that app. (How is
it possible!)

　　Then, I tried "heroku keys:add" to upload the generated public key...

　　But it is not done.

Next, I copied the .ssh directory from C:/User/XXX/ to
C:/Program files/Git/

　　And Type the "git clone" again.

Then it started to download...

I hope this may help some people.
