-## Installation
+## Setup
 
-Under construction!
+### Python dependencies
+
+This is set up as a Poetry project, so you must have [Poetry](https://python-poetry.org/docs/) installed and ready to go.
+
+Make sure you are using a [virtual environment](https://python-poetry.org/docs/managing-environments/) and then:
+
+```bash
+poetry install --with test,dev
+```
+
+### System dependencies
+
+In addition to the Python dependencies, you will also need to have [Hunspell](https://github.com/hunspell/hunspell)
+binaries installed on your system.
+
+The most important one is `unmunch`. Check if it's installed:
+
+```bash
+which unmunch
+# should return a path to a bin directory, like
+# /opt/homebrew/bin/unmunch
+```
+
+If it's not installed, you may need to compile Hunspell from source. Clone the [Hunspell repo](https://github.com/hunspell/hunspell)
+and then, from inside it, these steps should work on Ubuntu:
+```bash
+# install a bunch of dependencies needed for compilation
+sudo apt-get install autoconf automake autopoint libtool
+autoreconf -vfi
+./configure
+make
+sudo make install
+sudo ldconfig
+```
+
+### LT dependencies
+
+The scripts here also depend on the `languagetool` Java codebase (for word tokenisation).
+
+Make sure you have LT cloned locally, and export the following environment variable in your shell configuration:
+
+```bash
+export LT_HOME=/path/to/languagetool
+```
+
+If this is not done, the code in this project will set that variable as a default to `../languagetool` (meaning one
+directory up from wherever this repo is cloned).

 ⚠️ Note that the name of this repository is in **kebab-case**, but Python modules should be imported in **snake_case**.
 Therefore, when importing this as a submodule, make sure to set the path to `dict_tools`, which uses the underscore.
