+## Troubleshooting installation problems
+If you encounter problems with the installation check the following: 
+1. Make sure you have at least version 0.5 of neovim. 
+2. Make sure neovim was compiled with luajit. 
+  ```bash
+  # The output of version information should include a line for: LuaJIT 
+  nvim -v
+  ```
+3. If you ran the [quick-install script](#install-in-one-command) using sudo, follow the steps to [uninstall](#uninstalling) and try again without sudo. 
+4. Make sure the [dependencies](#useful-programs) were installed.  
+5. Make sure your plugins are installed and updated. Run :PackerSync

+Colorizer provides a setup function which must be called for the plugin to work correctly. So we create a folder 'lv-colorizer' and
