 I decided to start using [Robb Knight's Echo tool](https://echo.rknight.me), to syndicate my blog posts to Mastodon, and trigger Webmentions. I'm not going to go through the configuration of Echo here, the [project README](https://github.com/rknightuk/echo) has some good instructions for setting it up.

+---
+
+Welcome to Part Two of my series on Learning Go for WeblogPoMo. In this part, I'm going to look at how to organise my code into separate packages, so that I don't have to store everything in once single file.
+
+## Creating a package
+
+This was fairly straightforward. Packages are noted by the `package <name>` directive at the start of the file. You can even see that in `main.go`, which has `package.main` at the start. So, to create a package I added a directory for it (I'm calling it `maths`[^1]), and then added a `maths.go` file to it. For now, I'll just move the `multiply` function to it:
+
+```go
+package maths
+
+func multiply(a, b int) int {
+	return a * b
+}
+```
+
+Fairly straightforward, right?
+
+## Importing and running the code
+
+## Wait, what?
+
+## The vendor directory
+
+[^1]: Yes, maths, not math
