+# Set up a development environment
+
+We are providing instructions below to get and running you up if you want to
+build Zensical yourself and if you want to contribute to its development.
+
+!!! warning "Raise an issue before creating a pull request!"
+
+    Zensical is evolving rapidly and while we work hard to keep the user
+    experience stable, the implementation is still changing a lot. Since the
+    grounds are shifting fast, you must open an issue before you create a pull
+    request so that we can discuss what you want to work on. You must also read
+    the page on [pull requests], which provides further guidance.
+
+  [pull requests]: ../contribute/pull-requests.md
+
+## Prerequisites
+
+Zensical consists of a number of components, each with its own repository.
+Depending on which component you want to work on, you will need to install
+different development tools.
+
+To be able to build Zensical, you need to have the following installed:
+
+- [the `uv` package and project manager][uv]
+- a [Rust toolchain]
+- [Python]
+
+  [uv]: https://docs.astral.sh/uv/
+  [Rust toolchain]: https://rust-lang.org/tools/install/
+  [Python]: https://www.python.org/
+
+To build the templates, CSS, and TypeScript from the [UI repository], you will
+need these additional dependencies:
+
+- [Node.js]
+
+  [UI repository]: https://github.com/zensical/ui
+  [Node.js]: https://nodejs.org
+
+## Development setup
+
+To build Zensical, you need to:
+
+1. Check out the code from the [zensical repository] or from your own fork if
+   you are making a [pull request]:
+
+  [zensical repository]: https://github.com/zensical/zensical/
+  [pull request]: ../contribute/pull-requests.md
+
+    ```
+    git clone https://github.com/zensical/zensical.git
+    ```
+
+2. Run `uv sync` in the project directory to download and install the
+   dependencies into the project's virtual environment.
+
+3. Install the theme content by cloning the [UI repository] and making sure that
+   the contents of the `dist` directory appear under `python/zensical/templates`
+   in the Zensical project workspace:
+
+
+    === ":material-apple: macOS"
+
+        ```
+        git clone https://github.com/zensical/ui.git
+        ln -s ../../../ui/dist zensical/python/zensical/templates
+        ```
+
+    === ":material-linux: Linux"
+
+        ```
+        git clone https://github.com/zensical/ui.git
+        ln -s ../../../ui/dist zensical/python/zensical/templates
+        ```
+
+    === ":fontawesome-brands-windows: Windows (cmd.exe)"
+
+        ```
+        git clone https://github.com/zensical/ui.git
+        mklink ui\dist zensical\python\zensical\templates
+        ```
+
+        __Note:__ You need the right to create symbolic links to do this on Windows.
+
+    === ":fontawesome-brands-windows: Windows (Powershell)"
+
+        ```
+        git clone https://github.com/zensical/ui.git
+        New-Item -Type SymbolicLink -Path zensical\python\zensical\templates -Target ui\dist
+        ```
+
+        __Note:__ You need the right to create symbolic links to do this on Windows.
+
+## Building Zensical
+
+With these preparations out of the way, you can build Zensical by running:
+
+```
+uv run maturin develop
+```
+
+## Running Zensical
+
+To run Zensical from your project, either use `uv run zensical` or activate the
+virtual environment so you can just run `zensical`. The latter has the advantage
+that it works outside the project directory.
+
+## Building the themes
+
+To build the themes (modern and classic), change into the project directory for
+the UI repository and run:
+
+```
+npm install
+npm run build
+```
+
+Since the `dist` directory is symlinked into the Zensical project, the build
+artifacts will be immediately picked up by any new runs of Zensical.
