 ## Build Scripts
 
 Various build scripts are available over the `npm run` commands:
 
--   `bt` builds all assets and runs all tests in a smart order (without doing too many things if tests break)
--   `build` compiles all sources, tests to /dist and packs them browser-friendly to /lib-web
-    -   `build:node` compiles all TypeScript sources via `tsc` from /src to /dist and checks circular dependencies on /dist
-    -   `build:test` compiles all TypeScript tests via `tsc` from /test to /dist-test
-    -   `bundle` creates browser-friendly assets
-        -   `bundle:lib` bundles compiled distribution files to a browser-friendly asset via `webpack` from /dist to /lib-web (tsserval.js)
-        -   `bundle:min` bundles compiled distribution files to a compressed/minified browser-friendly asset via `webpack` from /dist to /lib-web (tsserval.min.js)
-        -   `bundle:test` bundles compiled test files to a browser-friendly form via `webpack` from /dist-test to /lib-web
--   `build:ci` is meant as build command for the pipeline and effectively runs `build` with a step in between, which replaces the runtime version informations in the respective file

 ## Test Setup
 
 Tests are written in TypeScript and executed in NodeJS and browser environments.
 
--   NodeJS tests are executed with the `mocha` testrunner and `node-ts` as TypeScript environment. Thus, running the NodeJS tests do not require a `build` step as `node-ts` is coping with the TypeScript compilation internally.
--   Browser tests are executed with `bt-runner` which uses `chromedriver` to test the bundled assets in compressed and uncompressed variants within the browser environment. The browser tests do not automatically `bundle` new builds, thus a browser build must be triggered before the browser tests.

 ## Test Scripts
 
 Various test scripts are available over the `npm run` commands:
 
--   `bt` builds all assets and runs all tests in a smart order (without doing too many things if tests break)
--   `test` runs all tests, first NodeJS then browser environment
-    -   `test:node` runs NodeJS tests with `node-ts`
-    -   `test:web` runs the tests on a browser environment with `bt-runner`
--   `test:server` runs a keep-alive version of `bt-runner` which can be used for debugging
