+# Documentation installation and setup
+
+This guide covers how to set up the documentation build environment for the Wazuh Docker documentation.
+
+## Prerequisites
+
+The documentation is built using [mdBook](https://rust-lang.github.io/mdBook/), a command-line tool for creating books
+with Markdown, along with [mdBook Mermaid](https://github.com/badboy/mdbook-mermaid) for diagram support.
+
+## Required versions
+
+- **mdbook**: 0.5.2
+- **mdbook-mermaid**: 0.17.0
+
+## Installation
+
+Install tools:
+
+```bash
+cargo install mdbook --version 0.5.2
+cargo install mdbook-mermaid --version 0.17.0
+``
+
+Verify installation:
+
+```bash
+mdbook --version
+mdbook-mermaid --version
+```
+
+## Building the documentation
+
+Once you have installed mdBook and mdBook Mermaid:
+
+```bash
+# Navigate to the docs directory
+cd docs
+
+# Build the documentation (generates html in docs/book/)
+mdbook build
+
+# Serve locally with live reload (recommended for development)
+mdbook serve --open
+```
+
+The documentation will be available at `http://localhost:3000` when using `mdbook serve`.
+
+## Development workflow
+
+When editing documentation:
+
+1. Run `mdbook serve --open` from the `docs/` directory
+2. Edit markdown files in `docs/ref/`
+3. Changes are automatically reflected in the browser
+4. Navigation structure is defined in `docs/SUMMARY.md`
+
+## Troubleshooting
+
+### Version mismatch errors
+
+If you encounter build errors, verify you have the correct versions installed:
+
+```bash
+mdbook --version
+mdbook-mermaid --version
+```
+
+If you have different versions, uninstall the current ones and reinstall by following the [Installation section](#installation):
+
+```bash
+cargo uninstall mdbook
+cargo uninstall mdbook-mermaid
+```
+
+### Cargo install fails with feature 'edition2024' is required
+
+You may see an error like:
+
+```sh
+failed to download `globset v0.4.18`
+failed to parse manifest ... feature `edition2024` is required
+The package requires the Cargo feature called `edition2024`, but that feature is not stabilized in this version of Cargo.
+```
+
+This happens because one of mdBook's transitive dependencies has been updated to use Rust edition 2024, which is only
+supported on nightly Rust toolchains.
+
+To fix it install using nightly Rust:
+
+```sh
+rustup install nightly
+rustup run nightly cargo install mdbook --version 0.4.52
+```
+
+### Mermaid diagrams not rendering
+
+If Mermaid diagrams are not rendering in the browser:
+
+1. Clear your browser cache
+2. Run `mdbook clean` to remove the build directory
+3. Run `mdbook serve --open` again
+
+### Port already in use
+
+If port 3000 is already in use, specify a different port:
+
+```bash
+mdbook serve --port 3001 --open
+```
