+## Development Guide
+
+### Development Environment Setup
+
+- Rust
+  - This project is built using the Rust programming language, and its build
+    tool Cargo. Information on how to install these tools is available on [the
+    Rust website](https://www.rust-lang.org/learn/get-started).
+- C Compiler
+  - This is used to built one of the dependencies, libgit2. This can be
+    obtained from your operating system's package manager.
+- Docker
+  - Some of the tests use Docker to create a simulated environment. This can be
+    obtained from your operating system's package manager, or the [Docker
+    website](https://www.docker.com/).
+  - Docker must be installed, with the `docker` executable on the path.
+  - Your user must have permission to use docker, including building and running
+    Docker containers.
+- Git
+  - Some of the tests use Git to test the end to end functionality of the
+    shell. This can be obtained from your operating system's package manager, or
+    the [Git website](https://git-scm.com/).
+  - Git must be installed, with the `git` executable on the path.
+- SSH
+  - Some of the tests use an SSH client to test the end to end functionality of
+    the shell. I have tested this with OpenSSH, which can be obtained from your
+    operating system's package manager, or the [Git website](https://git-scm.com/).
+  - with the `ssh` executable on the path.
+
+If you're running Arch Linux, these are the steps you'll need to get your
+environment ready.
+
+```sh
+sudo pacman -S rustup docker git openssh gcc
+
+# Rust
+rustup default stable
+
+# Docker
+sudo usermod -a -G docker $USER
+sudo systemctl start docker.service
+
+# Note: you need to log out and in again for the new group to take effect
+```
+
+### Running Tests
+
+All unit tests are run with Cargo.
+
+```sh
+cargo test
+```
+
+### Linting
+
+Clippy should be used for linting. This can be installed using Rustup.
+
+```sh
+rustup component add clippy
+```
+
+And it can be run via Cargo.
+
+```sh
+cargo clippy
+```
+
+### Building a Release Binary
+
+Release binaries should be built in release mode.
+
+```sh
+cargo build --release
+```
+
+After running this, the binary is available in `./target/release/shackle-shell`
