 ## Usage
 
-## Contribution
+## cli usage
+lets assume we have a directory called test/ where all our tests arae defined. Simply type
+
+```
+tstest test/
+```
+
+to run all tests.
+
+## Syntax
+tstest supports tap syntax. In other words your testfiles are run in a subprocess, and the console output contains trigger messages for tstest to determine test status. Inside your testfile you should use `@pushrocks/tapbundle` for the best results.
+
+## Environments
+
+tstest supports different environments:
+
+* a testfile called `test-something.node.ts` will be run in node
+* a testfile called `test-something.chrome.ts` will be run in chrome environment (bundled through parcel and run through puppeteer)
+* a testfile called `test-something.both.ts` will be run in node an chrome, which is good for isomorphic packages.
+
+> note: there is alpha support for the deno environment by naming a file test-something.deno.ts
