+### Timeout configuration
+
+In some cases (especially when attempting to install great amount of packages, [#1](https://github.com/SyntaxC4-MSFT/ComposerExtension/issues/1)) the deployment may timeout and the dependencies won't get loaded correctly by Composer. A simple fix is to add a [deployment configuration](https://github.com/projectkudu/kudu/wiki/Customizing-deployments) (create `.deployment` file) with parameter [**SCM_COMMAND_IDLE_TIMEOUT**](https://github.com/projectkudu/kudu/wiki/Configurable-settings) and set it to bigger number (for example `SCM_COMMAND_IDLE_TIMEOUT=600` where 600 is time out in seconds). The default value in Azure Web Apps for this setting appears to be 400 seconds.
