+# Running
+
+To run the embedded test, first prepare your environment:
+
+```shell
+sudo ./scripts/install-deps
+rustup target add thumbv7m-none-eabi
+```
+
+Then:
+
+```shell
+source ./scripts/env.sh && cargo run --target thumbv7m-none-eabi
+```
+
+Output should be something like:
+
+```text
+heap size 524288
+secp buf size 66240
+Seed WIF: L1HKVVLHXiUhecWnwFYF6L3shkf1E12HUmuZTESvBXUdx3yqVP1D
+Address: bc1qpx9t9pzzl4qsydmhyt6ctrxxjd4ep549np9993
+```
+
+Note that this heap size is required because of the amount of stack used by libsecp256k1 when initializing a context.
