 **Note** — Currently, the `--compile` flag can only accept a single entrypoint at a time and does not support the following flags:
 
 - `--outdir` — use `outfile` instead.
-- `--external`
 - `--splitting`
 - `--public-path`
 
 {% /callout %}
 
+## Deploying to production
+
+Compiled executables reduce memory usage and improve Bun's start time.
+
+Normally, Bun reads and transpiles JavaScript and TypeScript files on `import` and `require`. This is part of what makes so much of Bun "just work", but it's not free. It costs time and memory to read files from disk, resolve file paths, parse, transpile, and print source code. 
+
+With compiled executables, you can move that cost from runtime to build-time.
+
+When deploying to production, we recommend the following:
+
+```sh
+bun build --compile --minify --sourcemap ./path/to/my/app.ts --outfile myapp
+```
+
+**What do these flags do?**
+
+The `--minify` argument optimizes the size of the transpiled output code. If you have a large application, this can save megabytes of space. For smaller applications, it might still improve start time a little.
+
+The `--sourcemap` argument embeds a sourcemap compressed with zstd, so that errors & stacktraces point to their original locations instead of the transpiled location. Bun will automatically decompress & resolve the sourcemap when an error occurs.
+
 ## SQLite
 
 You can use `bun:sqlite` imports with `bun build --compile`.

+## `bun run`
+
+The `bun run` command can be configured under the `[run]` section. These apply to the `bun run` command and the `bun` command when running a file or executable or script.
+
+Currently, `bunfig.toml` isn't always automatically loaded for `bun run` in a local project (it does check for a global `bunfig.toml`), so you might still need to pass `-c` or `-c=bunfig.toml` to use these settings.
+
+### `run.shell` - use the system shell or Bun's shell
+
+The shell to use when running package.json scripts via `bun run` or `bun`. On Windows, this defaults to `"bun"` and on other platforms it defaults to `"system"`.
+
+To always use the system shell instead of Bun's shell (default behavior unless Windows):
+
+```toml
+[run]
+# default outside of Windows
+shell = "system"
+```
+
+To always use Bun's shell instead of the system shell:
+
+```toml
+[run]
+# default on Windows
+shell = "bun"
+```
+
+### `run.bun` - auto alias `node` to `bun`
+
+When `true`, this prepends `$PATH` with a `node` symlink that points to the `bun` binary for all scripts or executables invoked by `bun run` or `bun`.
+
+This means that if you have a script that runs `node`, it will actually run `bun` instead, without needing to change your script. This works recursively, so if your script runs another script that runs `node`, it will also run `bun` instead. This applies to shebangs as well, so if you have a script with a shebang that points to `node`, it will actually run `bun` instead.
+
+By default, this is enabled if `node` is not already in your `$PATH`.
+
+```toml
+[run]
+# equivalent to `bun --bun` for all `bun run` commands
+bun = true
+```
+
+You can test this by running:
+
+```sh
+$ bun --bun which node # /path/to/bun
+$ bun which node # /path/to/node
+```
+
+This option is equivalent to prefixing all `bun run` commands with `--bun`:
+
+```sh
+bun --bun run dev
+bun --bun dev
+bun run --bun dev
+```
+
+If set to `false`, this will disable the `node` symlink.
+
+### `run.silent` - suppress reporting the command being run
+
+When `true`, suppresses the output of the command being run by `bun run` or `bun`.
+
+```toml
+[run]
+silent = true
+```
+
+Without this option, the command being run will be printed to the console:
+
+```sh
+$ bun run dev
+> $ echo "Running \"dev\"..."
+Running "dev"...
+```
+
+With this option, the command being run will not be printed to the console:
+
+```sh
+$ bun run dev
+Running "dev"...
+```
+
+This is equivalent to passing `--silent` to all `bun run` commands:
+
+```sh
+bun --silent run dev
+bun --silent dev
+bun run --silent dev
