 First, run `pnpm i` to install all deps.
 
 We use TypeScript monorepo, each target is a separate package and has another package with tests. You need to run
 `pnpm watch` to automatically recompile all the projects as you introduce changes.
 
-Run `pnpm test:fix` before pushing, it will run eslint, prettier in fix mode and run all tests.

+NB: due to a [known issue](https://github.com/npm/cli/issues/3210) in the npm version newer than 6 it is not possible to
+start the commands. A quick fix is to downgrade the npm version `npm install -g [email protected]`.

+### Visual Code Solidity Version
+
+Since we develop using multiple versions of Solidity to avoid Linter errors from Visual Code in the following way we can
+set the current solidity version.
+
+1. Install the "Solidity" extension from the Marketplace
+2. Inside `.sol` file, run right click -> `Solidity: change workspace compiler version (remote)`
+3. Choose version from dropdown menu (0.6.4 or 0.8.9 or ...)
