That's it! If you're using custom port make sure it's the same as in the extension settings (default is `12212`).
## Configuration
[Here](https://github.com/karlicoss/grasp/blob/af24c991579986cec73695daa8318e7831049305/server/org_tools.py#L91-L109) you can find some references for the `--template` syntax.
If you are looking for more flexible formatting that's not supported by template syntax, see [config.py.example](misc/config.py.example).
You can modify it to your liking and pass as `--config` to `grasp_server/setup` scripts.
# Motivation
Why use org-capture? Well, it's hard to explain, maybe some other time... However, if you do know you want to use it instead of/alongside your browser bookmarks, by default
you don't have much choice and have to copy everything manually. For an experienced enough org-mode user it's no less than a torture.
