title: Adding annotations
|
|
order: 20
|
|
---
|
|
|
|
Our pattern is still a little bit *bare*. It would be nice to add some *annotations* to it.
|
|
|
|
When I say *annotations* it's an umbrella term for things like text or other
|
|
bits of information that help the user understand the pattern.
|
|
|
|
## Adding snippets
|
|
|
|
Snippets are little re-useable things to embellish our pattern with.
|
|
Things like buttons or buttonholes, a logo, or snaps.
|
|
|
|
To use them, much like points and paths, we need to destructure both
|
|
the `Snippet` constructor as well as the `snippets` object to hold
|
|
our snippets.
|
|
|
|
We'll be using them below to add a `snap-stud`, `snap-socket`, and a `logo`
|
|
snippet.
|
|
|
|
:::note
|
|
You can find all possible snippets in [our documentation](/reference/api/snippet/).

## Setting the cutlist, adding a title and scalebox
|
|
|
|
We are also going to add a title and scalebox. For both of these we will use a macro.
|
|
The `title` and `scalebox` macros to be precise.
|
|
|
|
Before we add the title, we will also set the cutlist via a method that was added to the
|
|
store by one of the core plugins.
|
|
|
|
As a matter of fact, all of these snippets, macros, and store methods are provided by plugins.
|
|
For more details, [refer to the plugin guide](/guides/plugins).
