+# Deployment
+
+Each Deployment looks different but some things are equals between multiple ways to deploy. This site list some best practises todo.
+
+## Plugins
+
+All Plugins should be managed by Composer. If you have project specific plugins you should put them into `custom/static-plugins` and require the plugin then or build them into the `src` directory without building a Plugin. You can refer also to [this Blog Post](https://shyim.me/blog/you-dont-need-a-plugin-to-customize-shopware-6/) if you want to customize Shopware without Plugins.
+
+## DB-less building
+
+When all plugins are installed with Composer, you can use `bin/ci` instead of `bin/console`. 
+This command does not use the Database for basic commands like `bundle:dump` which are required to build the Storefront / Administration assets. So in this way you can build all assets of your project once. 
+
+## Building assets
+
+When you are building the Assets make sure to set the following environment variables:
+
+```
+NODE_ENV=production
+# Disable Puppeteer Downloading
+PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true
+# Disable Typescript Checking
+DISABLE_ADMIN_COMPILATION_TYPECHECK=true
+# Build only the extensions not the Administration
+SHOPWARE_ADMIN_BUILD_ONLY_EXTENSIONS=1
+```
+
+## Composer
+
+There also some flags that are recommanded when you are using Composer:
+
+* `--no-dev` - Don't install dev dependencies (Profiler, use APP_DEBUG=1 in prod / stage debugging)
+* `--classmap-authoritative` - Generate only the class map. Disables on-the-fly finding classes.
+
+{{< hint info >}}
+Enabling classmap-authoritative with normal plugins installed (custom/plugins) will introduce a lot of performance issues and with Shopware 6.5 this will be disabled on the fly. Only use this option when all plugins are installed with Composer.
+{{< /hint >}}
+
+Also make sure that you set the correct PHP version inside the `composer.json` to fetch the dependencies for the right PHP version (without using the excact same version inside your CI).
+
+```json
+{
+    "config": {
+        "platform": {
+            "php": "8.1.8"
+        }
+    },
+    "require": {
+        ...
+    }
+}
+```
+
+## Splitting Tasks
+
+The most intensive tasks like building assets, installing composer packages should be done in the CI. And this artifact/image should be transfered to the production server. 
+
+From there you can update all plugins by `bin/console plugin:refresh` and `bin/console plugin:update ""` on the server. And maybe build the theme `bin/console theme:compile`.
