+## How do I setup code signing
+
+For code signing to work, you need to tell Xcode wich development team to use. This can be done in one of several way:
+
+### By setting the `DEVELOPMENT_TEAM` in the target's settings
+
+Simply specify your development team id in your `project.yml` file, like so:
+
+```yml
+# ...
+targets:
+  MyTarget:
+    # ...
+    settings:
+      DEVELOPMENT_TEAM: XXXXXXXXX
+```
+
+### By passing `DEVELOPMENT_TEAM` as an env variable
+
+You can also pass `DEVELOPMENT_TEAM` as an environemntal variable to `xcodebuild`, like so:
+
+```sh
+DEVELOPMENT_TEAM=XXXXXXXXX xcodebuild ...
+```
+
+### By using an `.xcconfig` file:
+
+The development team can also be read from `.xcconfig` files, this allows you to specify different teams for different build configurations. Start by creating an `.xcconfig` file with the value:
+
+```text
+DEVELOPMENT_TEAM = XXXXXXXXX
+```
+
+Then reference the `.xcconfig` file in your `project.yml` specification:
+
+```yml
+# ...
+targets:
+  MyTarget:
+    # ...
+    configFiles:
+      Debug: config_files/debug.xcconfig
+      Release: config_files/release.xcconfig
+```
