+## Toolchain
 The toolchain consists of 5 separate programs designed to work together:
 - [next_cluster](#next_cluster)
   - Determines the next cluster number in a directory of clusters

   - Similar to `simulate_one`, but runs a batch of simulations in a thread pool, intended for mass processing
   - Simulations share a generation limit, save points, and save interval, but not state
 
-Having separate programs creates flexibility by allowing users to orchestrate them as desired. A simple example script for creating clusters of simulations:
-
-```sh
-if [ $# -ne 2 ]; then
-    printf 'Usage: cluster.sh <out_dir> <sim_count>'
-    exit 1

+## Building
+
+For now the primary supported platform is Linux. As such, only Linux has a build system included. This project uses make.
+
+To build the toolchain in release (optimized) mode, run:
+
+```shell
+make -j $(nproc)
+```
+
+To build a specific program from the toolchain, run one of:
+
+```shell
+make -j $(nproc) next_cluster
+make -j $(nproc) make_states
+make -j $(nproc) make_image
+make -j $(nproc) simulate_one
+make -j $(nproc) simulate_many
+```
+
+To build the toolchain in debug mode, use `BUILD_TYPE=debug`:
+
+```shell
+# The whole toolchain:
+make -j $(nproc) BUILD_TYPE=debug
+
+# A specific program from the toolchain:
+make -j $(nproc) BUILD_TYPE=debug next_cluster
+make -j $(nproc) BUILD_TYPE=debug make_states
+make -j $(nproc) BUILD_TYPE=debug make_image
+make -j $(nproc) BUILD_TYPE=debug simulate_one
+make -j $(nproc) BUILD_TYPE=debug simulate_many
+```
+
+To build and run the testing suite in debug mode (recommended), run:
+
+```shell
+make -j $(nproc) BUILD_TYPE=debug tests && bin/debug/tests
+```
+
+To build and run the testing suite in release mode, run:
+
+```shell
+make -j $(nproc) tests && bin/release/tests
+```
+
+And the usual cleaning process:
+
+```shell
+make clean
+```
+
