+The command can be used to build a project of type "application" or "library".
+When used to build a library, a different builder is invoked, and only the `ts-config`, `configuration`, `poll` and `watch` options are applied.
+All other options apply only to building applications.
+
+The application builder uses the [esbuild](https://esbuild.github.io/) build tool, with default configuration options specified in the workspace configuration file (`angular.json`) or with a named alternative configuration.
+A "development" configuration is created by default when you use the CLI to create the project, and you can use that configuration by specifying the `--configuration development`.
+
+The configuration options generally correspond to the command options.
+You can override individual configuration defaults by specifying the corresponding options on the command line.
+The command can accept option names given in dash-case.
+Note that in the configuration file, you must specify names in camelCase.
+
+Some additional options can only be set through the configuration file,
+either by direct editing or with the `ng config` command.
+These include `assets`, `styles`, and `scripts` objects that provide runtime-global resources to include in the project.
+Resources in CSS, such as images and fonts, are automatically written and fingerprinted at the root of the output folder.
+
+For further details, see [Workspace Configuration](reference/configs/workspace-config).
