+# Customizing TailwindCSS
+
+Solidus Admin uses [Tailwind CSS](https://tailwindcss.com/) for styling. The
+benefit of using Tailwind is that it allows you to customize the look and feel
+of the admin without having to write any CSS. By leveraging utility classes,
+you can easily change the colors, fonts, and spacing in use.
+
+Solidus Admin provides a precompiled CSS file that includes all the necessary
+Tailwind classes for the admin to work out of the box.
+
+In case you need to customize the admin's look and feel, or create custom
+components, you can do so by running Tailwind's build process in your host
+application.
+
+This process presumes that you have a working knowledge of Tailwind CSS. If you
+are not familiar with Tailwind, please refer to the [Tailwind
+documentation](https://tailwindcss.com/docs) for more information.
+
+## Setting up a local TailwindCSS build for Solidus Admin
+
+In order to customize the admin's look and feel, you'll need to set up a local
+Tailwind build. This is a two-step process:
+
+Add Tailwind configuration files to your application:
+
+```shell
+bin/rails solidus_admin:tailwindcss:install
+```
+
+This will create all the necessary files for you to customize TailwindCSS,
+including:
+- A `config/solidus_admin/tailwind.config.js` configuration file
+  that will automatically import the Solidus Admin's default configuration.
+- An `app/assets/stylesheets/solidus_admin/application.tailwind.css` file
+  in which you can add your own customizations.
+- Tasks to build the CSS file once or watch for changes and automatically
+  rebuild the target `app/assets/builds/solidus_admin/application.css` file.
+
+In order to manually build the CSS file, run:
+
+```shell
+bin/rails solidus_admin:tailwindcss:build
+```
+
+Or, to watch for changes and automatically rebuild the CSS file, run:
+
+```shell
+bin/rails solidus_admin:tailwindcss:watch
+```
+
+## Caveats
+
+### Conflict with sassc-rails
+
+Tailwind uses modern CSS features that are not recognized by the sassc-rails extension that was included by default in the Gemfile for Rails 6. In order to avoid any errors like SassC::SyntaxError, you must remove that gem from your Gemfile.
+
