 # Docs Website
 
-All this site does is redirect to bptrace.org until we update the 
-DNS entry for docs.bpftrace.org to point to https://bpftrace.org/docs
+See https://github.com/bpftrace/website for instructions on working with a Docusaurus site.
+
+## Directory Structure
+
+The `docs` directory holds documentation for the in-development, unreleased bpftrace version. It should regularly pull in the docs from the bpftrace source repository.
+
+The `versioned_docs` directory holds snapshots of the docs from each released version. The latest version should be duplicated as both `version-x.y` and `version-latest`, to facilitate permalinks.
+
+## Updating Docs
+
+1. Update the versioned documentation snapshots:
+```
+rm -rf versioned_docs/version-latest
+cp -r docs versioned_docs/version-latest
+cp -r docs versioned_docs/version-x.y
+```
+
+2. Add the new version to `versions.json`, directly underneath `"latest"`.
+3. In `docusaurus.config.js`, update the version number in `config.presets.docs.versions` to refer to the new release.
