 ## Releasing

+You can create a test release by posting the below comment in your pull request:
+
+```bash
+@excalibot trigger release

+Once the version is released `@excalibot` will post a comment with the release version.

 ### Creating a production release
 
 To release the next stable version follow the below steps:
 
 ```bash
-yarn release --tag=latest --version=0.19.0
+yarn prerelease:excalidraw
 ```
 
-You will need to pass the `latest` tag with `version` for which you want to create the release. This will make the changes needed before publishing the packages into NPM, like updating dependencies of all `@excalidraw/*` packages, generating new entries in `CHANGELOG.md` and more.
+You need to pass the `version` for which you want to create the release. This will make the changes needed before making the release like updating `package.json`, `changelog` and more.
+
+The next step is to run the `release` script:

+yarn release:excalidraw
+```
+
+This will publish the package.
+
+Right now there are two steps to create a production release but once this works fine these scripts will be combined and more automation will be done.
