+# Build information
+*   Provides context about when the build was made and the corresponding Git revision.
+*   The information is displayed to the client when going in the about dialog.
+*   The build information is hard-coded in `apps/server/src/services/build.ts`. This file is generated automatically via `chore:update-build-info` which itself is run automatically whenever making a build in the CI.

+# Docker
+To build the server for Docker:
+
+*   Go to `apps/server` and run:
+    *   `pnpm docker-build-debian` or
+    *   `pnpm docker-build-alpine`.
+*   Similarly, to build the rootless versions: `pnpm docker-build-rootless-debian` or `pnpm docker-build-rootless-alpine`.
+*   To not only build but also run the Docker container, simply replace `docker-build` with `docker-start` (e.g. `pnpm docker-start-debian`).

+# Live reload (HMR)
+Trilium uses Vite's HMR (hot module reloading) mechanism.
+
+## Server live reload
+
+If running the server using `pnpm server:start`, the server will watch for changes. For React components, they will be hot-reloaded without requiring a refresh. For other services, it will reload the page.
+
+## Desktop live reload
+
+`pnpm desktop:start` acts the same as `pnpm server:start` with hot-reloading for client-side changes. Changes on the desktop side require a complete re-run of the `pnpm desktop:start` command.
