 If you are running on `localhost:3000` the default settings should work just fine.
 
-### Use custom hostname and port
+### Environment Variables
 
-To use a custom hostname and port:
+**`SERVER_NAME`** The url of your strider server. Defaults to `http://localhost:3000`.
 
-- set this environment variables with you hosname/port information
+The following variables only need to be overridden if you are using github enterprise. See 'Enterprise Setup' below.
 
-```
-PORT=9999
-SERVER_NAME="http://your.strider.hostname:9999"
-PLUGIN_GITHUB_APP_ID="hereComesTheId"
-PLUGIN_GITHUB_APP_SECRET="theSecretFromGithub"
-```
+**`PLUGIN_GITHUB_APP_ID`** Defaults to client ID of Strider-CD Github App
 
-- register your own github app [here](https://github.com/settings/applications/new) and set authentication URL your server's hostname:port + `/auth/github/callback`, for example:
+**`PLUGIN_GITHUB_APP_SECRET`** Defaults to client secret of Strider-CD Github App
 
-```
-http://your.strider.hostname:9999/auth/github/callback
-```
+**`PLUGIN_GITHUB_API_DOMAIN`** Defaults to `https://github.com`
 
-- also make sure your github profile has a public email set
+**`PLUGIN_GITHUB_API_ENDPOINT`** Defaults to `https://api.github.com`
+
+### Enterprise Setup
+
+1) You'll need to create an Application on your GitHub Enterprise Server. Log in to GitHub Enterprise and navigate to
+`https://your-github-url.com/settings/applications/new` and set authentication URL to
+`https://your-strider-server:port/auth/github/callback`.
+2) Define the environment variables. Here is an example:
+   ```
+   export SERVER_NAME="http://111.11.11.111:3000"
+   export PLUGIN_GITHUB_APP_ID="a342d32c23c23"
+   export PLUGIN_GITHUB_APP_SECRET="5af64a67af586847afbc6796769769d97a961"
+   export PLUGIN_GITHUB_API_DOMAIN="https://github.my-organization.com"
+   export PLUGIN_GITHUB_API_ENDPOINT="https://github.my-organization.com/api/v3"
+   ```
+   **NOTE** `SERVER_NAME` must be the same exact host that you used for the 'Authentication URL' in step 1. For example,
+   if you used `http://111.11.11.111:3000/auth/guthub/callback` in step 1, your `SERVER_NAME` **must** be
+   `http://111.11.11.111:3000`. Also note that the protocol must be the same between the two (if you used `http://`
+   in step 1, you must use `http://` in `SERVER_NAME` and not `https://`).
+3) Reboot strider and navigate link a github account as normal, you should see your enterprise repos!
+
+#### Known Issues with Enterprise
+
+- If you get 'Error: Could not fetch user profile': Somehow, passport will fail to retrieve the user profile unless all
+of the following are set. On GitHub Enterprise, log in to the profile you are trying to link to, and navigate to
+`/settings/profile`. Make sure the following are defined and set properly.
+   - Public Email
+   - Homepage URL
+
+#### Known Issues with GitHub.com
+
+- Make sure your github profile has a public email set
   * Go to https://github.com/settings/profile and select an email under "Public email".
