## Install/usage guide ## Secure Fetch
Secure fetch (aka authorised fetches, authenticated fetches, secure mode...) is *not* supported by mstdn-ebooks. Secure fetch requires that all incoming requests for posts are signed and originate from an authorised instance, and this is an impossible request for mstdn-ebooks to fulfill, as it's not an instance at all. Without getting too deep into the technical details, secure fetch means that the instance you're downloading posts from will check to see if the download request comes from an authorised instace (this usually means an instance that hasn't been defederated), and requires that each instance hosts a publicly accessible file to "prove" that it really is an authorised instance, as well as some other security measures (namely a HTTP signature). As mstdn-ebooks can not provide a publicly accessible file, as that would require running a web server, it is impossible to fulfill this request, and all of mstdn-ebooks' incoming requests will be denied by any instance using secure fetch.
There is no way around this - if Mastodon/Pleroma/etc were to implement a check that said "if it's an ebooks bot, let it through anyway", anyone could pretend to be an ebooks bot, even if they were on the blacklist. The only solution to this problem is to use software that can serve a publicly accessible file to prove that it's not on the blacklist, and this can only be done by software that operates on a server - something like FediBooks.
This problem is somewhat unique to the way mstdn-ebooks functions. Rather than using the Mastodon API to fetch posts, mstdn-ebooks uses ActivityPub outboxes. This has numerous benefits, such as:
- Ensuring that all public posts can be downloaded. If mstdn-ebooks used the Mastodon API, and your bot was on instance A, learning from a user on instance B, then mstdn-ebooks would only be able to "see" your posts that had already federated to instance A. This is a huge benefit, and the reason that I rewrote mstdn-ebooks to use ActivityPub outboxes in the first place.
- Not being tied to the Mastodon API
- Allowing for new ActivityPub compliant servers to be supported with ease
The only drawbacks are that the code is more complex (which doesn't affect the end user) and that mstdn-ebooks doesn't work with secure fetch (which only affects the end user if the instance has it enabled).
Note that as of the time of writing, FediBooks does not suport secure fetch either. This isn't because it would be impossible - rather, because I haven't implemented this feature yet. If you'd like to help, please get in contact with me on the Fediverse.
## Install/usage Guide
An installation and usage guide is available [here](https://cloud.lynnesbian.space/s/jozbRi69t4TpD95). It's primarily targeted at Linux, but it should be possible on BSD, macOS, etc. I've also put some effort into providing steps for Windows, but I can't make any guarantees as to its effectiveness.

*Note: Bots are only supported on Mastodon and Pleroma instances. Bots can learn from users on other instances, but the bot itself must run on either a Mastodon or Pleroma instance.*
mstdn-ebooks uses ActivityPub to download posts. This means that it is not dependant on any particular server software, and should work with anything that (properly) implements ActivityPub. Any software that does not support ActivityPub (e.g. diaspora*) is not supported, and won't work.
I recommend that you create your bot's account on a Mastodon instance. Creating a bot on a Pleroma instance means that your bot will be unable to reply. However, even if your bot is on a Mastodon instance, it will be able to learn from any Pleroma or Misskey users just fine.
## Configuration ## Configuration
Configuring mstdn-ebooks is accomplished by editing `config.json`. If you want to use a different file for configuration, specify it with the `--cfg` argument. For example, if you want to use `/home/lynne/c.json` instead, you would run `python3 main.py --cfg /home/lynne/c.json` instead of just `python3 main.py` Configuring mstdn-ebooks is accomplished by editing `config.json`.

## Donating
While mstdn-ebooks is currently feature complete, I still maintain it and fix critical issues. I also work on software other than mstdn-ebooks, and provide a few free services (OCRbot, FediBooks...) for people to use. If you'd like to help cover the costs of these projects, please consider donating.
- [Patreon](https://www.patreon.com/lynnesbian) allows you to "pledge" an amount and have it paid automatically, similar to a recurring subscription. Note that Patreon does not allow you to donate only a single time.
- [Ko-Fi](https://ko-fi.com/lynnesbian) allows you to make one-off payments in increments of AU$3. These payments are not taxed.
- [PayPal](https://paypal.me/lynnesbian) allows you to make one-off payments of any amount in a range of currencies. These payments may be taxed.
