+# Fake Firehose
+This project generates the mythical "firehose" relay that small Mastodon instances look for,
+at least to get content.
+
+It's a little crazy.
+
+Find a better way to do it and issue a pull request, or just tell me where your new repo is :)
+
+## How to run it
+
+Make sure you have `jq` installed.
+
+Linux:
+`apt install jq`
+
+macOS:
+`brew install jq`
+
+### 1. Fake Relay is Setup
+You need to have [fakerelay](https://github.com/g3rv4/FakeRelay) running and hooked up with your Mastodon instance.
+
+[Gervasio](https://mastodonte.tech/@g3rv4) is _the man_ for fakerelay.
+
+### 2. Environmental variables
+You need to have two environmental variables set:
+
+- fakeRelayHost
+- fakeRelayKey
+
+I recommend you put them in your `.bashrc` file. I use:
+
+```shell
+export fakeRelayKey="MrNtYH+GjwDtJtR6YCx2O4+TuldQ_SOMEKEY_aVni0rsbDryETCx9lHSZmzcOAv3Y8+4LiD8bFUZbnyl4w=="
+export fakeRelayHost="https://my-relay.raynor.haus/index"
+```
+
+### 3. Instances you want to follow
+Create a file `domains` and put once instance on each line that you want to follow. The top 50 by total accounts by what my instances sees is included.
+
+### 4. Start it up
+Open a terminal and run `./start-firehose.sh`
+
+This starts reading the public federated statuses stream of every instance in the `domains` file.
+
+Open a different terminal and run `./run-firehose.sh`
+
+This starts feeding the statuses to fakerelay.
+
+Profit.
+
+### 5. How to stop it
+Log out.
+
+No for real, I didn't get to that part yet.
+
+# Super important things to watch out for
+**AFTER YOU RUN `start-firehose.sh` IT WILL KICK OFF A SHELL SCRIPT IN THE BACKGROUND FOR EVERY DOMAIN YOU HAVE LISTED. THERE IS NO EASY WAY TO KILL THESE.**
+
+100% for real, run this in a VM or a container or somewhere you can log out if you overdid it to start.
+
+`run-firehose.sh` has a couple of important lines to look at.
+
+First: 
+
+`until [ $curls -lt 100 ]` 
+
+determines the _total_ number of `curl` executables that can be ran at once, system-wide. This includes one for each `domain` you have listed.
+
+If your curl limit is less than your domains number, than nothing will flow.
+
+If your curl limit is too high, your machine will run out of resources and lock up.
+
+Second: 
+
+`until [ $linesLeft -gt 500 ]` 
+
+sets how many statuses (aka posts, toots) have to be in a batch. **YOU NEED TO BATCH THESE** 
+
+_Most_ of the URIs will be duplicated, the beginning of `run-firehose.sh` de-duplicates the URIs. 500-1000 has been a good batch size in my experience.
