-## Publishing SDK's
+## Making Changes & Publishing
 
-Publishing of each SDK is done on merge to main using semantic-release and semantic-release-monorepo. PR titles / commits follow angular conventional commits with custom settings that map as follows:
+This repo uses [Changesets](https://github.com/changesets/changesets) for versioning and publishing, with the `workspace:` protocol for internal dependencies.
 
-```markdown
-- `fix(SDK name):` will trigger a patch version
-- `<type>(public):` will trigger a patch version
-- `feat(SDK name):` will trigger a minor version
-- `feat(breaking):` will trigger a major version for a breaking change
-- `chore(<scope>):` will not trigger a release
+### 1. Make your code changes on a branch
+
+Internal dependencies (e.g., `v4-sdk` depending on `sdk-core`) use the `workspace:` protocol, so they resolve to the local workspace during development. This means you can change multiple packages in a single PR — no need for sequential publish-wait-bump cycles.
+
+### 2. Add a changeset
+
+After making your changes, run:
+
+```
+yarn changeset
 ```
 
-Versions will only be generated based on the changelog of the relevant SDK's folder/files.
+This interactive CLI will ask you:
+- **Which packages should be bumped?** Select the packages you directly changed (e.g., `@uniswap/sdk-core`).
+- **What type of bump?** `patch`, `minor`, or `major`.
+- **Summary** A short description of the change (this becomes the changelog entry).
+
+This creates a markdown file in `.changeset/` that looks like:
+
+```md
+---
+"@uniswap/sdk-core": minor
+---
+
+Add support for Soneium chain
+```
+
+You **only need to list the packages you directly changed**. Changesets automatically bumps dependents (e.g., bumping `sdk-core` will also bump `v2-sdk`, `v3-sdk`, `v4-sdk`, `router-sdk`, `universal-router-sdk`, etc.).
+
+### 3. Open your PR
+
+Commit the changeset file alongside your code changes. Reviewers can see exactly what version bumps are planned.
+
+### 4. What happens on merge to `main`
+
+The CI workflow (`changesets/action`) runs automatically and does one of two things:
+
+- **If there are pending changeset files:** It opens (or updates) a **"Version Packages" PR** that bumps versions in every affected `package.json`, updates changelogs, and removes the consumed changeset files.
+- **If the "Version Packages" PR is merged:** It publishes all packages with new versions to npm.
+
+### Example: Adding a new chain
+
+Previously this required 4 sequential PRs with publish-wait-bump cycles. Now it's a single PR:
+
+```
+1. Edit sdk-core (add chain) + universal-router-sdk (use chain)
+2. Run `yarn changeset` and select both packages
+3. Open PR, merge
+4. Merge the auto-generated "Version Packages" PR
+5. All affected packages publish to npm
+```
+
+### Quick reference
+
+| Command | What it does |
+|---|---|
+| `yarn changeset` | Create a changeset file (run before opening your PR) |
+| `yarn version-packages` | Apply pending changesets to bump versions (CI does this) |
+| `yarn g:release` | Publish all bumped packages to npm (CI does this) |
