+
+::: info Work in progress
+
+This page is a draft, and doesn't contain all the necessary info to get up and running. Until this page is complete, please see [Automatic NativeScript App Deployments with fastlane](https://blog.nativescript.org/automatic-nativescript-app-deployments-with-fastlane/).
+
+:::
+
+Automating uploads to Apple AppStore and Android Play Store is a great way to save time on this otherwise manual, lengthy and error-prone process.
+
+NativeScript apps are built like any other native app, so publishing with Fastlane is generally a straight-forward process, allowing for customizations along the way to suit the project needs.
+
+## What we're setting up
+
+In this guide we'll set up the following:
+
+- automatic certificate handling via Fastlane-match
+- automatic ios builds that bump the build number, and upload to TestFlight
+- automatic android builds that bump the buiod number, and upload to a Play Store Internal Test Track
+- ...
+
+## General Fastlane setup
+
+Add a `Gemfile` to the root of the project:
+
+```ruby
+source "https://rubygems.org"
+
+gem "cocoapods"
+gem "dotenv"
+gem "fastlane"
+
+# Optional: if using Fastlane plugins in a Pluginfile
+# plugins_path = File.join(File.dirname(__FILE__), 'fastlane', 'Pluginfile')
+# eval_gemfile(plugins_path) if File.exist?(plugins_path)
+```
+
+## iOS specific Fastlane setup
+
+## Android specific Fastlane setup
