Update Setup.md

[Huddie]

Slight confusion recently with entitlements, simulators vs physical devices etc.
This update of the setup guide will hopefully remedy this

Some minor wording updates as well

I’m at work (on break) but would like to comment and offer some suggestions based on my observations installing and setting up the repo. I can do them later this afternoon. Would that be ok?

[Huddie]

@wayni208 Sure! sounds awesome!

Here are some changes I would suggest.

## 1. Cloning the repo
1. Create or navigation to a folder/directory where you’ll store the GitHawk project.

	Example: `mkdir ./desktop/GitHawkApp/`

2. In terminal clone the repo using: `git clone https://github.com/<YourGithubUsername>/GitHawk.git`

I would correct "navigation" to read "navigate" in 1. I would change 2 to say:

2. Open a terminal in the directory you just created or have selected to store the GitHawk project. In terminal, clone the repo using: `git clone https://github.com/<YourGithubUsername>/GitHawk.git`

In order to create "Copy of Freetime-AppCenter" the workspace must be open, allowing access to the schema. This is most of what I came here to say.

To add the Client ID and Client Secret to the App, follow these steps:

1. In Xcode, go to `Product` (in the Menu bar) > `Scheme` > `Manage Schemes...`
2. Select `Freetime-AppCenter` and click the cog.
3. Click on `Duplicate`.
4. Uncheck the `Shared` checkbox.
5. Select `Copy of Freetime-AppCenter` and click on `Edit...`
6. Go to `Run` > `Arguments`
7. Add your Client ID (`GITHUB_CLIENT_ID` as key) and Client Secret (`GITHUB_CLIENT_SECRET`) to the Environment Variables.

I would change this section like this:

To add the Client ID and Client Secret to the App, follow these steps:

1. In the directory you created, open the {YOUR_DIR}/GitHawk/Freetime.xcworkspace file.
2. In Xcode, go to `Product` (in the Menu bar) > `Scheme` > `Manage Schemes...`
3. Select `Freetime-AppCenter` and click the cog.
4. Click on `Duplicate`.
5. Select `Copy of Freetime-AppCenter` and uncheck "Shared" checkbox. 
6. With 'Copy of Freetime-Appcenter' selected, click on `Edit...`
6. Go to `Run` > `Arguments`
7. Add your Client ID (`GITHUB_CLIENT_ID` as key) and Client Secret (`GITHUB_CLIENT_SECRET`) to the Environment Variables.

Also, I am using Xcode 10 and when I duplicate the schema it immediately goes into edit mode. "Shared" is disabled by default.

My issues were after I set up for Code Signing. Perhaps a note in this portion to let the contributor know that project, extension, and plist files will be out of sync and to avoid committing them would be appropriate? While it might be convenient to place these files in .gitignore I have noticed on a recent PR that the project file was updated/altered to account for a new class.

I shall review and update! Thanks so much!
