 ### Documentation Generation
 - READMEs are auto-generated using helm-docs from `README.md.gotmpl` templates
 - Never edit `README.md` directly - edit the `.gotmpl` template
-- CI auto-generates and commits docs back to PRs
+- Run `just docs` locally before committing — CI will reject uncommitted changes

 # Changelog
 
 
+## 0.11.0
+
+- **BREAKING**: Change default session image from `rstudio/r-session-complete` to `rstudio/workbench-session` and enable session component delivery via init containers by default.
+  Set `components.enabled: false` and `session.image.repository: rstudio/r-session-complete` to restore the previous behavior
+- Add top-level `components` key for configuring session component init containers
+- Add `components.positron` for updating the Positron IDE version independently
+  of a Workbench release. A default Positron version is already delivered by the
+  `workbench-session-init` container. Set `components.positron.version` to
+  override it with a specific version
+
 ## 0.10.13
 
 - Bump Workbench version to 2026.01.2
 
-
 ## 0.10.12
 
 - Fix invalid JSON in default `positron-user-settings.json`

+## Session images
+
+By default, session pods use the `rstudio/workbench-session` image with an init container
+(`rstudio/workbench-session-init`) that delivers Workbench session components at pod startup.
+
+To use the classic all-in-one `r-session-complete` image instead (which bundles all components
+into a single image), disable session components and change the session image:
+
+```yaml
+session:
+  image:
+    repository: "rstudio/r-session-complete"
+components:
+  enabled: false
+```
+
+### Positron
+
+To enable Positron IDE support, set a Positron version under `components.positron`:
+
+```yaml
+components:
+  positron:
+    version: "2026.03.0"
+```
+
+This configures an init container that delivers Positron binaries and documentation to
+session pods. The version determines both the image tag and the server-side mount path.
