+# Release process
+
+First, make sure you are logged-in https://crates.io with: `cargo login`.
+If you don't have write access to **LanguageTool-Rust**' crates, you can still
+perform steps 1-4, and ask a maintainer with accesses to perform step 5.
+
+This project uses `cargo-release` to publish all packages with more ease.
+Note that, by default, every command runs in *dry mode*, and you need to append `--execute`
+to actually perform the action.
+
+Here are the following steps to release a new version:
+
+1. create a branch `release-x.y.z` from the `main` branch;
+2. run and commit `cargo release version --workspace <LEVEL>`;
+3. run and commit `cargo release replace --workspace`;
+4. push your branch and create a pull request;
+5. and, once your branch was merged to `main`, run the following:
+   ```bash
+   cargo release publish --package languagetool-rust
+   ```
+
+And voilà!
