* create a Mastodon API key following the instructions [here](https://tinysubversions.com/notes/mastodon-bot/)
* create a Twitter API key follwing the instructions [here](https://developer.twitter.com/en/docs/basics/authentication/guides/access-tokens)
* create a file called `config.edn` with the following contents:
```clojure
{:twitter {:access-keys
{:consumer_key "XXXX"
:consumer_secret "XXXX"
:access_token_key "XXXX"
:access_token_secret "XXXX"}
:accounts ["arstechnica" "WIRED"]} ;; accounts you wish to mirror
:mastodon {:access_token "XXXX"
:api_url "https://botsin.space/api/v1/"}}
```
* the bot looks for `config.edn` at its relative path by default, an alternative location can be specified either using the `MASTODON_BOT_CONFIG` environment variable or passing the path to config as an argument
