+            Themes are created with SASS using the <i>primevue-sass-theme</i> project available at <a href="http://github.com/primefaces/primevue-sass-theme">github</a>. This repository contains all the scss files for the components and the variables
+            of the built-in themes so that you may customize an existing theme or create your own. The scss variables used in a theme are available at the <a href="https://www.primefaces.org/designer/api/primevue/3.9.0">SASS API</a> documentation.
+        </p>
+        <p>
+            There are 3 alternatives to create your own theme. First option is using the Visual Editor, second one is compiling a theme with command line sass and final alternative is embedding scss files within your project to let your build
+            environment do the compilation. In all cases, the generated theme file should be imported to your project.
+        </p>
+
+        <h3>Visual Editor</h3>
+        <p>
+            <a href="https://designer.primevue.org">Visual Editor</a> is an easy way to quickly customize an existing theme without dealing with the details of the SASS API. The editor allows changing common settings like primary color for built-in
+            themes. Once you have completed the design, click the download button to access the generated <i>theme.css</i> file and import it to your project as an asset. In near future, an advanced UI Designer will be available with the ability to
+            edit all variables and components where you'll also be able to save your themes when accessed with an account.
+        </p>
+
+        <h3>Theme SCSS</h3>
+        <p>
+            The theme scss is availabe as open source at <a href="http://github.com/primefaces/primevue-sass-theme">primevue-sass-theme</a> repository. The <i>base</i> folder contains the theming structure of the components, themes under
+            <i>themes</i> folder define the SCSS variables and import the <i>base</i> to define a theme. The <i>themes</i> folder contains all the built-in themes so you can customize their code as well.
+        </p>
+        <p>
+            To create your own theme, clone the <a href="http://github.com/primefaces/primevue-sass-theme">primevue-sass-theme</a> repository and access the <i>themes/mytheme</i> folder. The sass variables to customize are available under the
+            <i>variables</i> folder. The <i>_fonts</i> file can be used to define a custom font for your project whereas the optional <i>_extensions</i> file is provided to add overrides to the components designs. The <i>theme.scss</i> file imports
+            the theme files along with the <i>base</i> folder at the root to combine everything together. Next step would be compilation of the scss that can either be command line or within your project.
+        </p>
+
+        <h3>Compile SCSS Manually</h3>
+        <p>Once your theme is ready run the following command to compile it. Note that <a href="https://www.npmjs.com/package/sass">sass</a> command should be available in your terminal.</p>
+        <DocSectionCode :code="code1" hideToggleCode importCode hideCodeSandbox hideStackBlitz />
+        <p>
+            Then copy and import the theme.css file in your application. For example, in a Vite based template like <a href="https://github.com/vuejs/create-vue">create-vue</a>, you may place theme.css under assets folder and then import it an
+            <i>main.js</i>.
+        </p>
+        <DocSectionCode :code="code2" hideToggleCode importCode hideCodeSandbox hideStackBlitz />
+
+        <h3>Build Time Compilation</h3>
+        <p>
+            This approach eliminates the manual compilation by delegating it to your build environment that has the ability to compile SCSS. Clone <a href="http://github.com/primefaces/primevue-sass-theme">primevue-sass-theme</a> and copy the
+            <i>base</i> folder along with <i>themes/mytheme</i> folder to your application where assets reside. At a suitable location like <i>main.js</i> or <i>App.vue</i>, import the <i>theme.scss</i> from <i>assets/themes/mytheme</i>. That would
+            be it, during build time, your project will compile the sass and import the theme. Any changes to your theme will be reflected instantly.
