+title: devspace add package
+---
+
+With `devspace add package`, you can easily add a package (helm chart) like mysql, nginx etc. to your devspace. To view all available packages run `devspace add package`.  
+
+The devspace add package command adds the helm chart as a dependency in the requirements.yaml and calls the internal `helm dependency update`, which downloads the chart and places it in the chart/charts folder. To remove the dependency call `devspace remove package PACKAGE`.  
+
+By default the standard stable helm chart repository is used (see: [Helm Charts](https://github.com/helm/charts/tree/master/stable)). If you want to add additional charts, just add the repository via `helm repo add` ([documentation](https://docs.helm.sh/helm/#helm-repo-add)).  
+
+```
+Usage:
+  devspace add package [flags]
+
+Flags:
+      --app-version string     App version
+      --chart-version string   Chart version
+  -h, --help                   help for package
+      --skip-question          Skips the question to show the readme in a browser
+
+Examples:
+devspace add package                                # Shows all available packages
+devspace add package mysql                          # Adds the mysql chart to the devspace
+devspace add package mysql --app-version=5.7.14     # Adds the mysql chart with app version 5.7.14 to the devspace
+devspace add package mysql --chart-version=0.10.3   # Adds the mysql chart with chart version 0.10.3 to the devspace
