-the `modules/cassandra/pages` subdirectory. The documentation uses [antora](http://www.antora.org/)
-and is thus written in [asciidoc](http://asciidoc.org).
 
-The `antora.yml` file is auto-generated and should not be manually edited. It is generated from the version in `build.xml` using `scripts/gen-antora-yml.py` and automatically detects whether building from a release tag or branch HEAD to set the appropriate version.
+The `antora.yml` file is auto-generated and should not be manually edited. It is generated from the version in `build.xml` using `scripts/gen-antora-yml.py` and automatically detects whether building from a release tag or branch HEAD to set the appropriate full or short version.
 
-To generate the asciidoc files (including antora.yml) for cassandra.yaml and the nodetool commands, run (from project root):
+The antora.yml and some of the asciidoc files are dynamically generated using `ant gen-asciidoc`.
-```bash
-ant gen-asciidoc
-```
-or (from this directory):
 
-```bash
+## Building HTML Pages
-make gen-asciidoc
-```
 
+To build the HTML documentation for this version only, you have two options:
 
-(The following has not yet been implemented, for now see the build instructions in the [cassandra-website](https://github.com/apache/cassandra-website) repo.)
+**Option 1: Using globally installed Antora** (requires Node.js, Antora and Pandoc installed):
-To build the documentation, run (from project root):
-
 ```bash
 ant gen-doc
 ```
-or (from this directory):
+This uses the `site-local.yml` antora playbook to build only the current in-tree version.
 
+**Option 2: Using Docker**:
 ```bash
-make html
+.build/docker/build-docs.sh
+```
+This uses the same Docker image as cassandra-website, with all tooling pre-installed.
+
+The HTML will be generated in `build/html/`.
+
+For building documentation across multiple Cassandra versions, see the build instructions in the [cassandra-website](https://github.com/apache/cassandra-website) repo.
+
+
+## Building Man Pages
+
+Building the html documentation also generates a manpages file.
+
+**View the man page**:
+```bash
+man ../build/man/cassandra-docs.7.gz
 ```
 
+**Note**: This creates a single comprehensive reference manual (section 7) containing all documentation.
