-## Usage
-
-To use `bytes`, first add this to your `Cargo.toml`:
-
-```toml
-[dependencies]
-bytes = "1"
-```
-
-Next, add this to your crate:
-
-```rust
-use bytes::{Bytes, BytesMut, Buf, BufMut};
-```
-
-## Serde support
-
-Serde support is optional and disabled by default. To enable use the feature `serde`.
-
-```toml
-[dependencies]
-bytes = { version = "1", features = ["serde"] }
-```
-
-## Building documentation
-
-When building the `bytes` documentation the `docsrs` option should be used, otherwise
-feature gates will not be shown. This requires a nightly toolchain:
-
-```
-RUSTDOCFLAGS="--cfg docsrs" cargo +nightly doc
-```
