 ## Building
 
+### Building using devx shell
+
 Building is performed with `cabal`inside IOG's `github:input-output-hk/devx` shell.
 See `.envrc` for details.
 
 Make sure to `cabal update` before building.
 
+### Building manually
+
+*Unsupported method: do on your own risk. Was tested on Arch Linux in 2024.*
+
+Manual installation for required binary dependencies is described here:
+https://github.com/input-output-hk/cardano-node-wiki/blob/main/docs/getting-started/install.md#installing-blst
+Arch Linux has libblst in AUR, which is alternative for building it manually.
+
+After installing  binary dependencies `cabal build` should work.
+
