+## Build the Fuzzer
+
+The fuzzer is split into an executable (in the [`app`](/app) folder) and a
+library (in the [`src`](/src) folder). To build the executable, you will need
+[stack](https://docs.haskellstack.org/en/stable/README/) installed. Building
+directly using [cabal-install](https://www.haskell.org/cabal/download.html) is
+possible but not recommended and not directly supported.
+
+To build the executable
+
+``` shell
+stack build
+```
+
+To run the executable
+
+``` shell
+stack exec verifuzz
+```
+
+To install the executable (which defaults to installing it in `~/.local`)
+
+``` shell
+stack install
+```
+
+## Running tests
+
+There are two test-suites that currently test the library. One of the
+test-suites tests the random code generation and generation of the acyclic
+graph. It also contains some property based tests for this. The other test-suite
+uses `doctest` to test the examples that are in the documentation.
+
+To run the test-suites
+
+``` shell
+stack test
+```
