title: About apple certificates and distribution
body: <p>I have some questions and cannot found any resource that clearly answers them all. I am really confused. If someone can answer all my questions I will appreciate
  What I want to achieve is the following: I am a developer and have a developer account. My client also has one account. He wants to upload to the store using his account. He doesn't want to give me his apple username/password. </p>
  
  <p>My questions are:</p>
  
  <ol>
  <li>I know that I have to sign the application. Can I sign using my developer certificate? Or should I use my client's one?</li>
  <li>How Can I add my client's developer certificate to my keychain? </li>
  <li>What exactly is the provisioning profile? The client sent me his provisioning profile. Do I need it?</li>
  <li>I tried to add his provisioning profile to xcode organizer and I get a message: Valid signing identity not found. What is that?</li>
  <li>Should I have to create an application on iTunes Connect?</li>
  <li>What should I send to the client? The archive? What else? </li>
  <li>I read that I have to put the Bundler Id in iTunes connect. I can see the following Bundle name in Xcode:  ${PRODUCT_NAME}. What should I write in iTunes?</li>
  <li>Step by step, could you give me an overview of what I should do? (i.e. download a certificate, sign release, create archive, create application on itunes, etc etc)</li>
  </ol>
  
  <p>If someone can answer my 8 question,  I will greatly appreciate.</p>
