 ## Development
 
 The development environment is managed by [Nix](https://nixos.org/download.html).
-Running `nix-shell` will spawn a shell with everything you need to get started with the project.
+Running `nix-shell` will spawn a shell with everything you need to get started with the lib.
 
 If you do not want to use Nix, you can either use [rustup](https://rust-lang.github.io/rustup/index.html):
 
-```text
+```
 rustup update
 ```
 
 or install manually the following dependencies:
 
 - [cargo](https://doc.rust-lang.org/cargo/)
-- [rustc](https://doc.rust-lang.org/stable/rustc/platform-support.html)
+- [rustc](https://doc.rust-lang.org/stable/rustc/platform-support.html) (`>= 1.87`)
 
 ## Build
 
 ```
 cargo build
 ```
 
-You can disable default [features](https://doc.rust-lang.org/cargo/reference/features.html) with `--no-default-features` and enable features with `--features feat1,feat2,feat3`.
-
-Finally, you can build a release with `--release`:
+## Test
 
 ```
-cargo build --no-default-features --release
+cargo test
+```
+
+## Override dependencies
+
+All Pimalaya crates use `[patch.crates-io]` to point to sibling directories.
+If you want to build io-dns against a locally modified dependency (e.g. `io-socket`), add the following to `Cargo.toml`:
+
+```toml
+[patch.crates-io]
+io-socket.path = "/path/to/io-socket"
 ```
