+# Installation
+
+## Installation
+
+Building GRM currently requires the nightly Rust toolchain. The easiest way
+is using [`rustup`](https://rustup.rs/). Make sure that rustup is properly installed.
+
+Make sure that the nightly toolchain is installed:
+
+```
+$ rustup toolchain install nightly
+```
+
+Then, install the build dependencies:
+
+| Distribution  | Command                                                                        |
+| ------------- | ------------------------------------------------------------------------------ |
+| Archlinux     | `pacman -S --needed gcc openssl pkg-config`                                    |
+| Ubuntu/Debian | `apt-get install --no-install-recommends pkg-config gcc libssl-dev zlib1g-dev` |
+
+Then, it's a simple command to install the latest stable version:
+
+```bash
+$ cargo +nightly install git-repo-manager
+```
+
+If you're brave, you can also run the development build:
+
+```bash
+$ cargo +nightly install --git https://github.com/hakoerber/git-repo-manager.git --branch develop
+```
+
+## Static build
+
+Note that by default, you will get a  dynamically linked executable.
+Alternatively, you can also build a statically linked binary. For this, you
+will need `musl` and a few other build dependencies installed installed:
+
+| Distribution  | Command                                                                     |
+| ------------- | --------------------------------------------------------------------------- |
+| Archlinux     | `pacman -S --needed gcc musl perl make`                                     |
+| Ubuntu/Debian | `apt-get install --no-install-recommends gcc musl-tools libc-dev perl make` |
+
+(`perl` and `make` are required for the OpenSSL build script)
+
+The, add the musl target via `rustup`:
+
+```
+$ rustup +nightly target add x86_64-unknown-linux-musl
+```
+
+Then, use a modified build command to get a statically linked binary:
+
+```
+$ cargo +nightly install git-repo-manager --target x86_64-unknown-linux-musl --features=static-build
+```
