+## Requirements
+
+⚠️ Ensure the following requirements before merging ⚠️
+- [ ] Automated tests have been added.
+- [ ] If some tests cannot be automated, manual rigorous tests should be applied.
+- [ ] ⚠️ If there is any change in the DB: 
+    - [ ] Test that any impacted DB still works as expected after using `--experimental-dumpless-upgrade` on a DB created with the last released Meilisearch
+    - [ ] Test that during the upgrade, **search is still available** (artificially make the upgrade longer if needed)
+    - [ ] Set the `db change` label.
+- [ ] If necessary, the feature have been tested in the Cloud production environment (with [prototypes](./documentation/prototypes.md)) and the Cloud UI is ready.
+- [ ] If necessary, the [documentation](https://github.com/meilisearch/documentation) related to the implemented feature in the PR is ready.
+- [ ] If necessary, the [integrations](https://github.com/meilisearch/integration-guides) related to the implemented feature in the PR are ready.

+This issue is about updating Meilisearch dependencies:
+  - [ ] Update Meilisearch dependencies with the help of `cargo +nightly udeps --all-targets` (remove unused dependencies) and `cargo upgrade` (upgrade dependencies versions) - ⚠️ Some repositories may contain subdirectories (like heed, charabia, or deserr). Take care of updating these in the main crate as well. This won't be done automatically by `cargo upgrade`.
+    - [ ] [deserr](https://github.com/meilisearch/deserr)
+    - [ ] [charabia](https://github.com/meilisearch/charabia/)
+    - [ ] [heed](https://github.com/meilisearch/heed/)
+    - [ ] [roaring-rs](https://github.com/RoaringBitmap/roaring-rs/)
+    - [ ] [obkv](https://github.com/meilisearch/obkv)
+    - [ ] [grenad](https://github.com/meilisearch/grenad/)
+    - [ ] [arroy](https://github.com/meilisearch/arroy/)
+    - [ ] [segment](https://github.com/meilisearch/segment)
+    - [ ] [bumparaw-collections](https://github.com/meilisearch/bumparaw-collections)
+    - [ ] [bbqueue](https://github.com/meilisearch/bbqueue)
+    - [ ] Finally, [Meilisearch](https://github.com/meilisearch/MeiliSearch)
+  - [ ] If new Rust versions have been released, update the minimal Rust version in use at Meilisearch:
+    - [ ] in this [GitHub Action file](https://github.com/meilisearch/meilisearch/blob/main/.github/workflows/test-suite.yml), by changing the `toolchain` field of the `rustfmt` job to the latest available nightly (of the day before or the current day).
+    - [ ] in every [GitHub Action files](https://github.com/meilisearch/meilisearch/blob/main/.github/workflows), by changing all the `dtolnay/rust-toolchain@` references to use the latest stable version.
+    - [ ] in this [`rust-toolchain.toml`](https://github.com/meilisearch/meilisearch/blob/main/rust-toolchain.toml), by changing the `channel` field to the latest stable version.
+    - [ ] in the [Dockerfile](https://github.com/meilisearch/meilisearch/blob/main/Dockerfile), by changing the base image to `rust:<target_rust_version>-alpine<alpine_version>`. Check that the image exists on [Dockerhub](https://hub.docker.com/_/rust/tags?page=1&name=alpine). Also, build and run the image to check everything still works!
+
+⚠️ This issue should be prioritized to avoid any deprecation and vulnerability issues.
+
+The GitHub action dependencies are managed by [Dependabot](https://github.com/meilisearch/meilisearch/blob/main/.github/dependabot.yml), so no need to update them when solving this issue.

   The draft PRs are recommended when you want to show that you are working on something and make your work visible.
 - The branch related to the PR must be **up-to-date with `main`** before merging. Fortunately, this project uses [GitHub Merge Queues](https://github.blog/news-insights/product-news/github-merge-queue-is-generally-available/) to automatically enforce this requirement without the PR author having to rebase manually.
 
-## Release Process (for internal team only)

-### Automation to rebase and Merge the PRs
+## Merging PRs
 
 This project uses GitHub Merge Queues that helps us manage pull requests merging.
 
-### How to Publish a new Release
+Before merging a PR, the maintainer should ensure the following requirements are met
+- Automated tests have been added.
+- If some tests cannot be automated, manual rigorous tests should be applied.
+- ⚠️ If there is an change in the DB: it's mandatory to manually test the `--experimental-dumpless-upgrade` on a DB of the previous Meilisearch minor version (e.g. v1.13 for the v1.14 release).
+- If necessary, the feature have been tested in the Cloud production environment (with [prototypes](./documentation/prototypes.md)) and the Cloud UI is ready.
+- If necessary, the [documentation](https://github.com/meilisearch/documentation) related to the implemented feature in the PR is ready.

 ### How to publish a prototype
 
 Depending on the developed feature, you might need to provide a prototyped version of Meilisearch to make it easier to test by the users.
 
 This happens in two steps:
-- [Release the prototype](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#how-to-publish-a-prototype)
-- [Communicate about it](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#communication)

+### How to implement and publish an experimental feature
