 ## Installation
 
+There are two main ways to install `py-bitcoinkernel`:
+1) Installing a pre-compiled wheel from PyPI, if it is available for
+   your platform. This is the fastest way to install `py-bitcoinkernel`,
+   and does not introduce any further dependencies. This approach
+   requires you to trust the wheel build system.
+2) Installing from source and letting `pip` compile the dependencies
+   locally. This allows you to compile `libbitcoinkernel` from source,
+   and is the only way to install `py-bitcoinkernel` on platforms where
+   a pre-compiled wheel is not available. It is significantly slower than
+   installing a wheel, and requires a number of dependencies to be
+   installed.
+
+### Install from wheel
+
+To install a pre-compiled wheel from PyPI, simply run:
+
+```
+pip install --pre py-bitcoinkernel
+```
+
+### Install from source
+
+You can clone this repository and run:
+
+```
+pip install .
+```
+
+Alternatively, you can install the source distribution from PyPI:
+
+```
+pip install --pre py-bitcoinkernel --no-binary :all:
+```

+> [!NOTE]
+> When installing from source, `pip` will automatically compile
+> `libbitcoinkernel` from the bundled source code in `depend/bitcoin/`.
+> This process may take a while. To inspect the build progress, add -`v`
+> to your `pip` command, e.g.  `pip install . -v`.
