-
-#### Prerequisites
-
-In order to download necessary tools, clone the repository, and install dependencies via `npm` you need network access.

-
-#### Build and Run
-
-If you want to understand how Random Bunny works or want to debug an issue, you'll want to get the source, build it, and run the tool locally.
-
-First, fork the Random Bunny repository so that you can make a pull request. Then, clone your fork locally:
-
-```bash
-git clone https://gitlab.vylpes.com/<your-gitlab-account>/random-bunny.git
-```
-
-Occasionally, you will want to merge changes in the upstream repository (the official code repo) with your fork.
-
-```bash
-cd Random Bunny
-git checkout master
-git pull https://github.com/getgravitysoft/random-bunny.git master
-```
-
-Manage any merge conflicts, commit them, and then push them to your fork.
-
-Go into `Random Bunny` and start the bot in dev mode with `npm run dev` or `node bot dev`
-
-> **Note:** If you have `nodemon` installed on your system you can use this during development so it auto restarts when you make code changes. Instead of the commands above you can then run `nodemon bot dev`.
-
-#### Pull Requests

-
-Please follow these steps to have your contribution considered by maintainers:
-
-* You mention the issue id which this pull request aims to fix
-* After you submit your pull request, verify that all status checks are passing.
-
-> **Note**: If a check fails the pull request it is important that you go and fix these issues, or let us know that you no longer want to work on this issue by commenting on the pull request. Doing this will give you a better chance of having your pull request merged.
-
-* When the checks have passed a maintainer will review your code and ask for any improvements or questions, and will merge it if they are satisifed.
-
-While the prerequesites above must be satisifed prior to having your pull reuqest accepted, the reviewer(s) may ask you to complete additional design ork, tests, or other changes before your pull request can be ultimately accepted.
-
-#### JavaScript Styleguide
-
-All JavaScript code is linted with `eslint`.
-
-* Prefer camelcase for variable names
-* Prefer braces `{` to be on the same line
-* Prefer no comma `,` dangle
-* Prefer arrow function bodies to have brances `{}` only when needed
-* Prefer arrow function parameters to have brackets `()` only when needed
-* Prefer arrow function arrows `=>` to have a space before and after it
-* Prefer `let` and `const` over `var`
-
-As well as eslint's recommended defaults.
-
-Example
-
-```js
-function ban (member) {
-    let reason = "Example reason";
-
-    member.ban(reason).then(() => {
-        // handle then here

+# CLI
+
+Since Version 2.2, Random Bunny contains a command line interface (CLI).
+
+## Downloads
+
+The project can be downloaded as a binary for your system via the [GitHub Releases](https://github.com/Vylpes/random-bunny/releases) or [Forgejo Releases](https://git.vylpes.xyz/RabbitLabs/random-bunny/releases) page.
+
+We currently support:
+- Linux (x64)
+- Windows (x64)
+- macOS (x64, Arm64\*)
+
+The git repository can also be cloned and ran via `yarn build` and `yarn start`.
+
+You can produce the binary using the `yarn package` command. This creates the binaries in the `./bin` folder.
+
+> **NOTE:** We are aware of a bug in the macOS Arm64 builds failing to execute. For now you're still able to use the x64 builds under Rosetta fine. This will hopefully be fixed in a future release.
+
+## Default Output
+
+By default, the command will fetch a random image from `r/rabbits` and return it in a human-readable output.
+
+```
+$ random-bunny
+
+Archived = false
+Author = Rabbit_Owner
+Downvotes = 0
+Hidden = false
+Permalink = /r/Rabbits/comments/1av1rg9/cute_baby_bun/
+Subreddit = Rabbits
+Subreddit Subscribers = 486084
+Title = Cute baby bun
+Upvotes = 211
+Url = https://i.redd.it/sfz0srdrimjc1.png
+```
+
+## Help
+
+The command also includes a help option in case you are stuck.
+
+```
+$ random-bunny --help
+
+# or
+
+$ random-bunny -h
+
+Usage: random-bunny [options]
+
+Get a random image url from a subreddit of your choosing
+
+Options:
+  -V, --version                output the version number
+  -s, --subreddit <subreddit>  The subreddit to search (default: "rabbits")
+  -j, --json                   Output as JSON
+  -q, --query-metadata         Include query metadata in result
+  -o <file>                    Output to file
+  --sort <sort>                Sort by (choices: "hot", "new", "top", default: "hot")
+  --limit <limit>              The amount of posts to fetch from the reddit api (default: 100)
+  -h, --help                   display help for command
+```
+
+## JSON output
+
+You can also convert the output into JSON, if you need to input it to another program.
+
+```bash
+$ random-bunny --json
+
+# or
+
+$ randon-bunny -j
+
+{"Archived":false,"Author":"Rabbit_Owner","Downs":0,"Hidden":false,"Permalink":"/r/Rabbits/comments/1av1rg9/cute_baby_bun/","Subreddit":"Rabbits","SubredditSubscribers":486085,"Title":"Cute baby bun","Ups":210,"Url":"https://i.redd.it/sfz0srdrimjc1.png"}
+```
+
+## Sort
+
+You can also choose the sorting option which reddit will use to return the available posts to randomise from.
+
+This defaults to "hot". The valid options are "hot", "new", and "top".
+
+```
+$ random-bunny --sort hot
+$ random-bunny --sort new
+$ random-bunny --sort top
+```
+
+
+## Subreddit
+
+You can change the subreddit which the command fetches from.
+
+This defaults to "rabbits"
+
+```
+$ random-bunny --subreddit rabbits
+$ random-bunny -s horses
+```
+
+## Output to file
+
+If you'd rather send the output to a file, you can supply the `-o` flag.
+
+```
+$ randombunny -o ~/Desktop/output.txt
+```
+
+## Reddit API Return Limits
+
+You can also limit the amount the posts the script requests from the Reddit API
+using the `--limit` option.
+
+This defaults to 100. This accepts any number between 1 and 100.
+
+Please note limiting the calls to less than 100 will give a higher chance of
+the script not finding any valid image post to return.
+
+```
+$ random-bunny --limit 50
+```
