+# Separate Startup Script
+
+This config sources a separate startup script so that you can edit a `nu` script
+instead of fiddling around with the `toml` config.
+
+Additionally it provides some new commands:
+
+- `config edit`: Opens the `config.toml` in a new editor (depending on the `EDITOR` env variable)
+- `startup edit`: Opens the `startup.nu` in a new editor (depending on the `EDITOR` env variable)
+- `startup path`: Like `config path` provides the path to the `startup.nu` file
+
+
+## The `... edit` command
+
+Both `config edit` and `startup edit` accept the flag `--editor` (or `-e`) that
+lets you define a different editor. To open the config in
+[VSCode](https://github.com/microsoft/vscode) VScode for example do:
+
+```
+config edit -e code
+startup edit -e code
+```
+
+
+## The `... path` command
+
+Like `config path` the command `startup path` provides the path to the
+`startup.nu` file. This can be used e.g. to open both, the `config.toml` and the
+`startup.nu` in an editor of your choice:
+
+```
+vim (config path) (startup path)
+```
