+# How to publish a new release
+
+## 1. Ensure you're fully in sync with the remote repo
+
+```bash
+git switch main
+git pull
+git status
+```
+
+## 2. Create the release branch
+
+```bash
+git switch -c vX.Y.Z
+```
+
+## 3. Update all the occurrences of the version in the repo
+
+```bash
+bump2version --config-file .bumpversion.cfg <increment>
+```
+
+The `increment` parameter can be:
+
+- `patch`
+- `minor`
+- `major`
+
+Use the one appropriate to the version increment you're releasing.
+
+## 4. Refresh `Cargo.lock`
+
+```bash
+cd questdb-rs-ffi
+cargo clean
+cargo build
+```
+
+## 5. Merge the release branch to master
+
+```bash
+git commit -m "Bump version: <current> → <new>"
+```
+
+Replace the `<current>` and `<new>` placeholders!
+
+Create and merge a PR with the same name: "Bump version: \<current\> → \<new\>"
+
+## 6. Tag the new version
+
+Once the PR is merged, pull main and add the version tag:
+
+```bash
+git switch main
+git pull --prune
+git tag X.Y.Z
+git push --tags
+```
+
+## 7. Create a new release on GitHub
+
+[GitHub Release Page](https://github.com/questdb/c-questdb-client/releases)
+
+On that page you'll see all the previous releases. Follow their manually-written
+style, and note that the style differs between patch, minor, and major releases.
+
+## 8. Publish the Rust crate to crates.io
+
+Ensure once more you're fully in sync with the remote repo:
+
+```bash
+git switch main
+git pull
+git status
+```
+
+Publish the crate:
+
+```bash
+cd questdb-rs
+cargo publish --dry-run --token [your API token from crates.io]
+cargo publish --token [your API token from crates.io]
+```
+
+## 9. Ensure the docs are online on docs.rs
+
+The release is immediately visible on crates.io, but there's a delay until it
+becomes available on [https://docs.rs/](docs.rs). Watch that site and ensure it
+appears there.
