 PyPi installation includes prebuilt libraries for common platforms (win, macos, linux, raspi) - see [`src/embit/util/prebuilt/`](./src/embit/util/prebuilt/) folder. Library is built from [libsecp-zkp](https://github.com/ElementsProject/secp256k1-zkp) fork for Liquid support, but will work with pure [libsecp256k1](https://github.com/bitcoin-core/secp256k1) as well - just Liquid functionality doesn't work. If it fails to use the prebuilt or system library it will fallback to pure python implementation.

+We are using the **libsecp256k1** fork - [**secp256k1-zkp**](https://github.com/ElementsProject/secp256k1-zkp).
+
+Start by cloning `embit` with the `--recursive` flag:
+```sh
+git clone --recursive https://github.com/diybitcoinhardware/embit.git
+```
+
+This will automatically pull in the `libsecp256k1-zkp` repo and checkout the correct commit within that repo.

+This directory (`secp256k1/` in the `embit` root) already has a fully-configured Makefile to run the compilation for you.
 
+On your target platform run:
 ```sh

-To clean build directory use:
+Copy the resulting binary from the `build/` subdir to `embit`'s `src/embit/util/prebuilt` directory.
 
+To clean build directory use:
 ```shell
