-# Contributing to TFHE-rs
-
-This document provides guidance on how to contribute to **TFHE-rs**.
-
-There are two ways to contribute:
-
-- **Report issues:** Open issues on GitHub to report bugs, suggest improvements, or note typos.
-- **Submit codes**: To become an official contributor, you must sign our Contributor License Agreement (CLA). Our CLA-bot will guide you through this process when you open your first pull request.
-
-## 1. Setting up the project
-
-Start by [forking](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo) the **TFHE-rs** repository.
-
-{% hint style="info" %}
-- **Rust version**:  Ensure that you use a Rust version >= 1.81 to compile **TFHE-rs**.
-- **Incompatibility**: AArch64-based machines are not yet supported for Windows as it's currently missing an entropy source to be able to seed the [CSPRNGs](https://en.wikipedia.org/wiki/Cryptographically_secure_pseudorandom_number_generator) used in **TFHE-rs**.
-- **Performance**: For optimal performance, it is highly recommended to run **TFHE-rs** code in release mode with cargo's `--release` flag.
-{% endhint %}
-
-To get more details about the library, please refer to the [documentation](https://docs.zama.ai/tfhe-rs).
-
-## 2. Creating a new branch
-
-When creating your branch, make sure to use the following format :
-
-```
-git checkout -b {feat|fix|docs|chore…}/short_description
-```
-
-For example:
-
-```
-git checkout -b feat/new_feature_X
-```
-
-## 3. Before committing
-
-### 3.1 Linting
-
-Each commit to **TFHE-rs** should conform to the standards of the project. In particular, every source code, docker or workflows files should be linted to prevent programmatic and stylistic errors.
-
-- Rust source code linters: `clippy`
-- Typescript/Javascript source code linters: `eslint`, `prettier`
-
-To apply automatic code formatting, run:
-
-```
-make fmt
-```
-
-You can perform linting of all Cargo targets with:
-
-```
-make clippy_all_targets
-```
-
-### 3.2 Testing
-
-Your contributions must include comprehensive documentation and tests without breaking existing tests. To run pre-commit checks, execute:
-
-```
-make pcc
-```
-
-This command ensure that all the targets in the library are building correctly.
-For a faster check, use:
-
-```
-make fpcc
-```
-
-If you're contributing to GPU code, run also:
-
-```
-make pcc_gpu
-```
-
-Unit testing suites are heavy and can require a lot of computing power and RAM availability.
-Whilst tests are run automatically in continuous integration pipeline, you can run tests locally.
-
-All unit tests have a command formatted as:
-
-```
-make test_*
-```
-
-Run `make help` to display a list of all the commands available.
-
-To quickly test your changes locally, follow these steps:
- 1. Locate where the code has changed.
- 2. Add (or modify) a Cargo test filter to the corresponding `make` target in Makefile.
- 3. Run the target.
-
-{% hint style="success" %}
-`make test_<something>` will print the underlying cargo command in STDOUT. You can quickly test your changes by copy/pasting the command and then modify it to suit your needs.
-{% endhint %}
-
-For example, if you made changes in `tfhe/src/integer/*`, you can test them with the following steps:
- 1. In `test_integer` target, replace the filter `-- integer::` by `-- my_new_test`.
- 2. Run `make test_integer`.
-
-## 4. Committing
-
-**TFHE-rs** follows the conventional commit specification to maintain a consistent commit history, essential for Semantic Versioning ([semver.org](https://semver.org/)).
-Commit messages are automatically checked in CI and will be rejected if they do not comply, so make sure that you follow the commit conventions detailed on [this page](https://www.conventionalcommits.org/en/v1.0.0/).
-
-## 5. Rebasing
-
-Before creating a pull request, rebase your branch on the repository's `main` branch. Merge commits are not permitted, thus rebasing ensures fewer conflicts and a smoother PR review process.
-
-## 6. Opening a Pull Request
-
-Once your changes are ready, open a pull request.
-
-For instructions on creating a PR from a fork, refer to GitHub's [official documentation](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request-from-a-fork).
-
-## 7. Continuous integration
-
-Before a pull request can be merged, several test suites run automatically. Below is an overview of the CI process:
-
-```mermaid

-## Useful details:
-
-- pipeline is triggered by humans
-- review team is located in Paris timezone, pipeline launch will most likely happen during office hours
-- direct changes to CI related files are not allowed for external contributors
-- run `make pcc` to fix any build errors before pushing commits
-{% endhint %}
-
-## 8. Data versioning
-
-Data serialized with TFHE-rs must remain backward compatible. This is done using the [tfhe-versionable](https://crates.io/crates/tfhe-versionable) crate.
-
-If you modify a type that derives `Versionize` in a backward-incompatible way, an upgrade implementation must be provided.
-
-For example, these changes are data breaking:
- * Adding a field to a struct.
- * Changing the order of the fields within a struct or the variants within an enum.
- * Renaming a field of a struct or a variant of an enum.
- * Changing the type of field in a struct or a variant in an enum.
-
-On the contrary, these changes are *not* data breaking:
- * Renaming a type (unless it implements the `Named` trait).
- * Adding a variant to the end of an enum.
-
-## Example: adding a field
-
-Suppose you want to add an i32 field to a type named `MyType`. The original type is defined as:
-```rust
-#[derive(Serialize, Deserialize, Versionize)]
-#[versionize(MyTypeVersions)]
-struct MyType {
-  val: u64,
-}
-```
-And you want to change it to:
-```rust
-#[derive(Serialize, Deserialize, Versionize)]
-#[versionize(MyTypeVersions)]
-struct MyType {
-  val: u64,
-  other_val: i32
-}
-```
-
-Follow these steps:
-
- 1. Navigate to the definition of the dispatch enum of this type. This is the type inside the `#[versionize(MyTypeVersions)]` macro attribute. In general, this type has the same name as the base type with a `Versions` suffix. You should find something like
-
-```rust
-#[derive(VersionsDispatch)]
-enum MyTypeVersions {
-  V0(MyTypeV0),
-  V1(MyType)
-}
-```
-
- 2. Add a new variant to the enum to preserve the previous version of the type. You can simply copy and paste the previous definition of the type and add a version suffix:
-
-```rust
-#[derive(Version)]
-struct MyTypeV1 {
-  val: u64,
-}
-
-#[derive(VersionsDispatch)]
-enum MyTypeVersions {
-  V0(MyTypeV0),
-  V1(MyTypeV1),
-  V2(MyType) // Here this points to your modified type
-}
-```
-
- 3. Implement the `Upgrade` trait to define how we should go from the previous version to the current version:
-```rust
-impl Upgrade<MyType> for MyTypeV1 {
-  type Error = Infallible;
-
-   fn upgrade(self) -> Result<MyType, Self::Error> {
-       Ok(MyType {
-           val: self.val,
-           other_val: 0
-        })
-   }
-}
-```
-
- 4. Fix the upgrade target of the previous version. In this example, `impl Upgrade<MyType> for MyTypeV0 {` should simply be changed to `impl Upgrade<MyTypeV1> for MyTypeV0 {`

 ### Security model
 
-By default, the parameter sets used in the High-Level API with the x86 CPU backend have a failure probability $\le 2^{128}$ to securely work in the IND-CPA^D model using the algorithmic techniques provided in our code base [1].
-If you want to work within the IND-CPA security model, which is less strict than the IND-CPA-D model, the parameter sets can easily be changed and would have slightly better performance. More details can be found in the [TFHE-rs documentation](https://docs.zama.ai/tfhe-rs).
+The default parameters for the TFHE-rs library are chosen considering the IND-CPA security model, and are selected with a bootstrapping failure probability fixed at p_error = $2^{-64}$. In particular, it is assumed that the results of decrypted computations are not shared by the secret key owner with any third parties, as such an action can lead to leakage of the secret encryption key. If you are designing an application where decryptions must be shared, you will need to craft custom encryption parameters which are chosen in consideration of the IND-CPA^D security model [1].

+The same implementation is also available for generic Ciphertexts representing bits (meant to be used with parameters `V1_0_PARAM_MESSAGE_1_CARRY_1_KS_PBS_GAUSSIAN_2M128`).
 It uses a lower level API of tfhe-rs, so the syntax is a little bit different. It also implements the `TransCiphering` trait. For optimization purposes, it does not internally run
 on the same cryptographic parameters as the high level API of tfhe-rs. As such, it requires the usage of a casting key, to switch from one parameter space to another, which makes
 its setup a little more intricate.
