+Hello and welcome! This folder has been automatically generated by `@changesets/cli`, a build tool that works
+with multi-package repos, or single-package repos to help you version and publish your code. You can
+find the full documentation for it [in our repository](https://github.com/changesets/changesets)

+# Releasing
+
+This document describes the release process for the LI.FI Widget packages.
+
+## Overview
+
+The project uses [Changesets](https://github.com/changesets/changesets) to manage versioning and releases. The release process is automated through GitHub Actions workflows.
+
+## Release Process
+
+### 1. Creating Changesets
+
+When making changes that affect package versions, contributors need to create a changeset:
+
+1. Run `pnpm changeset` to create a new changeset file
+2. Select the packages affected by your changes
+3. Choose the version bump type (patch, minor, or major)
+4. Write a description of your changes
+5. Commit the changeset file along with your changes
+
+Changesets accumulate in the `.changeset/` directory and can be batched together before versioning.
+
+### 2. Automated Version PR Creation
+
+When changesets are merged to `main`, the versioning process is automated:
+
+1. The "Changesets" workflow automatically runs on every push to `main`
+2. If there are pending changesets, it creates a "Version Packages" PR with all accumulated changesets
+3. Review and merge the version PR to bump versions and update changelogs
+4. After merging, create and push a git tag matching the new version (e.g., `v3.34.2`)
+5. Pushing the tag will automatically trigger the publish workflow to build and publish packages to npm
+
+This allows multiple changes to be batched into a single release version. The workflow only creates a version PR when there are pending changesets, so it won't create empty PRs if no changesets exist.
+
+### 3. Publishing
+
+After the version PR is merged and a git tag is pushed:
+
+- The `publish.yaml` workflow automatically triggers
+- Packages are built and published to npm
+- A GitHub Release is created automatically
+- For alpha/beta tags, packages are published with the corresponding npm tag
+
+## Manual Release Commands
+
+If you need to manually trigger parts of the release process:
+
+- `pnpm release:version` - Bump versions and update changelogs
+- `pnpm release:build` - Build all packages
+- `pnpm release:publish` - Build and publish to npm (requires NPM_TOKEN)
+- `pnpm release:publish:alpha` - Publish alpha snapshot release
+- `pnpm release:publish:beta` - Publish beta snapshot release
+
+## Workflow Files
+
+- `.github/workflows/changesets.yml` - Automatically creates version PRs on push to main
+- `.github/workflows/publish.yaml` - Publishes packages when git tags are pushed
+- `.github/workflows/changeset-check.yml` - Validates that PRs include changesets
