+### GitHub Token
+
+GitHub token is used in both `shipjs prepare` and `shipjs trigger`.
+
+1. Go to https://github.com/settings/tokens/new
+2. Check "repo(Full control of private repositories)"
+3. Generate/copy the token
+
+You can put it in the following two ways:
+
+1. Prepend it in your command like: `GITHUB_TOKEN=xxx shipjs prepare`
+2. Create a file named ".env" and put the following content: `GITHUB_TOKEN=xxx`
+   (".env" should not be committed. Add it to ".gitignore".)
+
+If you automate flows in your CI, you can add the token to Environment Variable section in your CI service.

 ### Before running Shipjs
