## Overview
Users should be able to use the CLI with any WriteFreely instance -- not just Write.as.
This should involve a rebranding of the Write.as CLI to make it clear to users that the client works with any instance.
## Implementation
* Create a new `.writefreely` directory in the user's home directory
* Add a `-host` or `-h` flag that allows user to specify which instance to interact with
* When they successfully perform an action on an instance, save that information to a folder in `~/.writefreely`:
* instance directory: `~/.writefreely/[host]`
* posts: `~/.writefreely/[host]/[username]/posts.json`
* user data: `~/.writefreely/[host]/[username]/user.json`
* Future interactions with that instance should load the corresponding data from the instance's data directory
### posts.json
Should contain the JSON array of posts returned in the `data` property from the `/api/me/posts` endpoint.
### user.json
Should contain the full JSON object returned in the `data` property from the `/api/auth/login` endpoint. This includes the `access_token` needed for all authenticated requests.
## Questions
We should probably provide a way to indicate the default instance and username for CLI operations, so users don't have to include them every time.
