 ## Adding a test case for your project
 
 To add a test case for your project, please follow the following steps:
-- [X] Fork https://github.com/bincode-org/bincode
-- [X] create a new file `compatibility/src/<name>.rs`.
-- [X] Add a link to your project: https://github.com/ppamorim/openraft/tree/bincode-bug/example-raft-kv
-- [X] Add `Licence: MIT OR Apache-2.0` if you agree to distribute your code under this license
-- [X] Add a `mod <name>;` in the `lib.rs`. Make sure it's alphabetically ordered (check the ordering in your file system).
-- [X] Add your structs.

   - Adding references to libraries is not recommended. Libraries will not be implementing `bincode 2`'s encoding/decoding system.
   - If you need references to libraries, consider adding a test case for that library, and then referencing that test.
-- [X] Make sure structs derive the following traits:
-  - [X] `serde::Serialize` and `serde::Deserialize`, like normal
-  - [X] `bincode_2::Encode` and `bincode_2::Decode`, for the bincode 2 encode/decode mechanic
-  - [X] Because the crate is renamed to `bincode_2`, you also need to add `#[bincode(crate = "bincode_2")]`
-  - [X] `Debug, PartialEq`
