+# Katsu-Don: A Firefox Extension Downloader
+This is a tool that allows you to download multiple extensions to seperate .xpi files from addons.mozilla.org
+
+# Building
+The only requirement is that you have [go](https://golang.org/) installed.
+
+1) `go mod init katsu-don`
+2) `go build katsu-don`
+
+Alternativley, you can download a pre-compiled build [here](https://tildegit.org/kiiwiiwastaken/katsu-don/releases)
+
+# Usage:
+The first things you'll need to know is what extension numbers you'll be downloading. In this example, we'll be using numbers `1234567` and `1234569`.
+
+Run the command as follows:
+
+```
+./katsu-don -start 1234567 -end 1234569
+```
+
+`-start 1234567` is the first extension number that it will download.
+`-end 1234569` is the last extension number that it will download.
+
+Any number in between the start and end will also be downloaded. (In this case, `1234568`)
+
+# TODO:
+- [ ] Add a way to save the extension as the name itself, not the number it uses.
+- [ ] Add a search functionality.
