+
+An implementation of SHA-2 hash algorithms for batch and stream computation.
+
+## Setup
+
+To use this crate, add the following entry to your `Cargo.toml` file in the `dependencies` section:
+
+```toml
+[dependencies]
+chksum-hash-sha2 = "0.0.0"
+```
+
+Alternatively, you can use the [`cargo add`](https://doc.rust-lang.org/cargo/commands/cargo-add.html) subcommand:
+
+```shell
+cargo add chksum-hash-sha2
+```
+
+## Usage
+
+Use the `hash` function for batch digest calculation.
+
+```rust
+use chksum_hash_sha2::sha2_256;
+
+let digest = sha2_256::hash(b"example data");
+assert_eq!(
+    digest.to_hex_lowercase(),
+    "44752f37272e944fd2c913a35342eaccdd1aaf189bae50676b301ab213fc5061"
+);
+```
+
+Use the `default` function to create a hash instance for stream digest calculation.
+
+```rust
+use chksum_hash_sha2::sha2_512;
+
+let digest = sha2_512::default()
+    .update("example")
+    .update(b"data")
+    .update([0, 1, 2, 3])
+    .digest();
+assert_eq!(
+    digest.to_hex_lowercase(),
+    "57f35477757af6734892604de3846a97d2cc17cd37068373075e56a4843b3e9c83f9b435beae9fcf1da590e73e62fe20468f52ff13b095241fec77884086b090"
+);
+```
+
+For more usage examples, refer to the documentation available at [docs.rs](https://docs.rs/chksum-hash-sha2/).
+
+## Features
+
+Cargo features are used to enable or disable specific algorithm functions.
+
+* `224` enables SHA-2 224, accessible via the `sha2_224` module,
+* `256` enables SHA-2 256, accessible via the `sha2_256` module,
+* `384` enables SHA-2 384, accessible via the `sha2_384` module,
+* `512` enables SHA-2 512, accessible via the `sha2_512` module.
+
+By default all of them are enabled.
+
+To customize your setup, turn off the default features and enable only those that you want in your `Cargo.toml` file:
+
+```toml
+[dependencies]
+chksum-hash-sha2 = { version = "0.0.0", default-features = no, features = ["256", "512"] }
+```
+
+Alternatively, you can use the [`cargo add`](https://doc.rust-lang.org/cargo/commands/cargo-add.html) subcommand:
+
+```shell
+cargo add chksum-hash-sha2 --no-default-features --features 256,512
+```

+
+## Setup
+
+To use this crate, add the following entry to your `Cargo.toml` file in the `dependencies` section:
+
+```toml
+[dependencies]
+chksum-hash-sha2 = "0.0.0"
+```
+
+Alternatively, you can use the [`cargo add`](https://doc.rust-lang.org/cargo/commands/cargo-add.html) subcommand:
+
+```shell
+cargo add chksum-hash-sha2
+```
+
+## Usage
+
+Use the `hash` function for batch digest calculation.
+
+```rust
+use chksum_hash_sha2::sha2_256;
+
+let digest = sha2_256::hash(b"example data");

+);
+```
+
+Use the `default` function to create a hash instance for stream digest calculation.
+
+```rust
+use chksum_hash_sha2::sha2_512;
+
+let digest = sha2_512::default()
+    .update("example")
+    .update(b"data")
+    .update([0, 1, 2, 3])
+    .digest();
+assert_eq!(
