+# Natsuki
+The official repository of Natsuki the Discord Bot. Currently in the Early Development phase, and is expected to release to a few servers and eventually bot lists relatively soon.
+
+## Utils
+*Some useful stuff we have in our bot that you can make use of!*
+
+Just about anything in the utils folder could be useful for a number of reasons, but here's a few big ones:
+
+### Tags
+> util/tagfilter.js and util/tag.js
+
+Pass in a list of Tags. Each Tag has a list of triggers, its name, then its mode.
+
+- `toggle` = takes no options. If the tag is present, it will view as `true` in `options`.
+- `append` = forms a string from the text after the tag. `-title Something Cool` will return the string `Something Cool`. Will append from all tags that trigger the alias, so if multiple `title` tags are present, all of them will be present in the same string.
+- `listAppend` = Behaves like `append`, with the exception that it will return a list where each member is a string for every time the tag is used; see example below
+
+```js
+let options = new TagFilter([
+    new Tag(['t', '-title'], 'title', 'append'),
+    new Tag(['a', 'aliases', 'alts'], 'aliases', 'listAppend'),
+    new Tag(['f', 'force'], 'force', 'toggle')
+]).test(args.join(" "));
+
+// -title Example -a AnotherName -a Some other name -f
+
+// options will look like this
+{
+   title: "Example",
+   aliases: ["AnotherName", "Some other name"],
+   force: true
+}
+```
+
+### Quick awaitMessages
+> util/ask.js
+
+Ask a question and wait for an answer. Returns the string of the user's response, or nothing if there was no response. **Function is asynchronous!**
+
+*Please make sure you account for the chance of timeout.*
+
+Pass in your `message` object, the question to ask, the time - in ms - the user has to respond, and an optional boolean of whether or not to disable the filter, which would make it so that any user can answer the question.
+
+```js
+let name = await ask(message, "What is your name?", 30000);
+if (!name) {return;} // Function already sends a timeout message, just return here to stop the command from continuing.
+return message.channel.send(`Hiya there, ${name}!`);
+```
