+
+<!-- Explain what your extension does. -->
+
+## Installation
+
+Add solidus_friendly_promotions to your Gemfile:
+
+```ruby
+gem 'solidus_friendly_promotions'
+```
+
+Bundle your dependencies and run the installation generator:
+
+```shell
+bin/rails generate solidus_friendly_promotions:install
+```
+
+## Usage
+
+<!-- Explain how to use your extension once it's been installed. -->
+
+## Development
+
+### Testing the extension
+
+First bundle your dependencies, then run `bin/rake`. `bin/rake` will default to building the dummy
+app if it does not exist, then it will run specs. The dummy app can be regenerated by using
+`bin/rake extension:test_app`.
+
+```shell
+bin/rake
+```
+
+To run [Rubocop](https://github.com/bbatsov/rubocop) static code analysis run
+
+```shell
+bundle exec rubocop
+```
+
+When testing your application's integration with this extension you may use its factories.
+You can load Solidus core factories along with this extension's factories using this statement:
+
+```ruby
+SolidusDevSupport::TestingSupport::Factories.load_for(SolidusFriendlyPromotions::Engine)
+```
+
+### Running the sandbox
+
+To run this extension in a sandboxed Solidus application, you can run `bin/sandbox`. The path for
+the sandbox app is `./sandbox` and `bin/rails` will forward any Rails commands to
+`sandbox/bin/rails`.
+
+Here's an example:
+
+```
+$ bin/rails server
+=> Booting Puma
+=> Rails 6.0.2.1 application starting in development
+* Listening on tcp://127.0.0.1:3000
+Use Ctrl-C to stop
+```
+
+### Releasing new versions
+
+Please refer to the [dedicated page](https://github.com/solidusio/solidus/wiki/How-to-release-extensions) in the Solidus wiki.
