 Read our documentation about the [Developer Workflow](https://developers.mattermost.com/extend/plugins/developer-workflow/) and [Developer Setup](https://developers.mattermost.com/extend/plugins/developer-setup/) for more information about developing and extending plugins.
 
-Run `make memelibrary` to bundle up the meme assets (images, fonts, etc.).

 For convenience, you can run the plugin from your terminal to preview an image for a given input. For example, on macOS, you can run the following to generate the above meme and open it in Preview:
 
 `go run server/plugin.go -out demo.jpg 'memes. memes everywhere' && open demo.jpg`
 
-This is especially useful when adding or modifying memes as you can quickly modify assets, `make memelibrary`, and preview the result using the above command. (See the files in ` memelibrary/assets` to get started with that.)
