+### Faster Compiles
+
+We use extism for our plugins, unfortunately extism has quite a hefty impact on compile times, which can increase it by several minutes on release mode. To run Pumpkin without plugins, run the following:
+
+```shell
+cargo run --no-default-features
+```
+
+And in release:
+
+```shell
+cargo run --no-default-features --release
