 ## Installation from source
 
-Direct installation from source, while possible via `cabal install haskell-language-server`
+Direct installation from source, while possible via `cabal install exe:haskell-language-server`
 and `stack install --stack-yaml stack-<GHCVER>.yaml`, is not recommended for most people.
 Said command builds the `haskell-language-server` binary and installs it in the default `cabal` binaries folder,
 but the binary will only work with projects that use the same GHC version that built it.
