+# bs: Build system based on executables
+This project uses [jaandrle/bs: The simplest possible build system using executable/bash scripts](https://github.com/jaandrle/bs).
+
+## Available executables
+If it makes sense, arguments are passed to internally used commands (e.g. `tsc`), e. g. `--help`.
+
+### bs/lint
+This lints the project using `tsc`.
+
+### bs/test
+This lints the project and runs tests using `wtr`.
+
+### bs/start
+This starts the development server using `web-dev-server`.
+
+### bs/build
+This builds the project using `rollup`.
+
+### bs/analyze
+This analyze Custom Element manifest using the `@custom-elements-manifest/analyzer`.
+
+### bs/npm/lint
+Linted projects’ npm dependencies.
+
+### bs/npm/update
+Updates projects’ npm dependencies.
+
+### bs/npm/install-audit
+Audits projects’ npm dependencies to be installed.
