## To update the lit bundle
Using `mach`s `npm` you can update the bundle with:
Vendoring runs off of the latest tag in the https://github.com/lit/lit repo. If
the latest tag is a lit@ tag then running the vendor command will update to that
version. If the latest tag isn't for lit@, you may need to bundle manually. See
the moz.yaml file for instructions.
### Using mach vendor
```
cd toolkit/content/vendor/lit
../../../../mach npm run vendor
./mach vendor toolkit/content/vendor/lit/moz.yaml
hg ci -m "Update to lit@<version>"
```
Then commit the changes.
### Manually updating the bundle
To manually update, you'll need to checkout a copy of lit/lit, find the tag you
want and manually run our import commands.
1. Clone https://github.com/lit/lit outside of moz-central
2. Copy *.patch from this directory into the lit repo
3. git apply *.patch
4. npm install && npm run build
5. Copy packages/lit/lit-all.min.js to toolkit/content/widgets/vendor/lit.all.mjs
6. hg ci -m "Update to lit@<version>"
