Make sure that solc is installed and it's the same version of the file.  solc-select is recommended.

Solidity language server is a LSP with autocomplete, go to definition and diagnostics.

If you use brownie, use this root_dir:
root_dir = util.root_pattern('brownie-config.yaml', '.git')

on includePath, you can add an extra path to search for external libs, on remapping you can remap lib <> path, like:

```lua
{ solidity = { includePath = '/Users/your_user/.brownie/packages/', remapping = { ["@OpenZeppelin/"] = 'OpenZeppelin/openzeppelin-contracts@4.6.0/' } } }
```

**For brownie users**
Change the root_dir to:

```lua
root_pattern("brownie-config.yaml", ".git")
```

The best way of using it is to have a package.json in your project folder with the packages that you will use.
After installing with package.json, just create a `remappings.txt` with:

```
@OpenZeppelin/=node_modules/OpenZeppelin/openzeppelin-contracts@4.6.0/
```

You can omit the node_modules as well.
