Wekan v4.29 changes markdown rendering from [marked](https://github.com/markedjs/marked) to [markdown-it](https://github.com/markdown-it/markdown-it).
## About emoji
With markdown-it, also [markdown-it-emoji](https://github.com/markdown-it/markdown-it-emoji) plugin has been added, supporting [full list of GitHub emojis](https://github.com/markdown-it/markdown-it-emoji/blob/master/lib/data/full.json).
Example emoji code, that you can add for example to card name, card description etc:
```
:rainbow: :thumbsup: :100:
```
That shows emojis :rainbow: :thumbsup: :100:
## About other markdown-it plugins
For markdown-it, there are also other [syntax extensions](https://github.com/markdown-it/markdown-it#syntax-extensions) where some are listed at that markdown-it page, and [others at npmjs.com](https://www.npmjs.org/browse/keyword/markdown-it-plugin).
For example, how to get some [mermaid plugin](https://www.npmjs.com/search?q=markdown-it-mermaid) working so that some syntax works for https://mermaid-js.github.io/mermaid/ ?
That does: 1 install dependencies, 2 builds wekan, 3 starts wekan in development mode with command `meteor`, so it can detect if some file changes and try to rebuild automatically and reload webbroser. But, still sometimes, it may need stopping with Ctrl-c and full build with option 2.
### OPTIONAL, NOT NEEDED: 5. Add new plugin package
```
meteor npm install markdown-it-something --save
```
Edit file `wekan/packages/markdown/src-integration.js` and add using that new package, using code example from that new plugin page, or similar like emoji plugin was added.
