+### Release process
+
+To release a new version of SDK:
+1. Make sure that version strings have been updated:
+   - Eppo core: [eppo_core/Cargo.toml](eppo_core/Cargo.toml)
+   - Rust: [rust-sdk/Cargo.toml](rust-sdk/Cargo.toml)
+   - Python: [python-sdk/Cargo.toml](python-sdk/Cargo.toml)
+   - Ruby: [ruby-sdk/lib/eppo_client/version.rb](ruby-sdk/lib/eppo_client/version.rb) and [ruby-sdk/ext/eppo_client/Cargo.toml](ruby-sdk/ext/eppo_client/Cargo.toml)
+2. If SDK depends on a new version of `eppo_core`, the core should be released first.
+3. [Create a new release](https://github.com/Eppo-exp/rust-sdk/releases/new) in GitHub interface.
+   - For tag, use one of the following formats (choose "create new tag on publish"):
+     - `eppo_core@x.y.z`
+     - `rust-sdk@x.y.z`
+     - `python-sdk@x.y.z`
+     - `ruby-sdk@x.y.z`
+   - For generating release notes, select previous tag from the same SDK (e.g., when releasing `python-sdk@4.0.3`, the previous tag should be `python-sdk@4.0.2`). Auto-generate release notes, prune entries that are not relevant for the SDK (e.g., Python SDK release should not list PRs for Ruby).
+   - Publish release.
+   - CI will automatically push a new release out to package registries.
