Custom Plugins

Neovim-flake, by default, exposes a wide variety of plugins as module options for your convience and bundles necessary dependencies into neovim-flake's runtime. In case a plugin is not available in neovim-flake, you may consider making a pull request to neovim-flake to include it as a module or you may add it to your configuration locally.

Adding Plugins

There are multiple way of adding custom plugins to your neovim-flake configuration.

You can use custom plugins, before they are implemented in the flake. To add a plugin, you need to add it to your config's vim.startPlugins array.

Adding a plugin to startPlugins will not allow you to configure the plugin that you have addeed, but neovim-flake provides multiple way of configuring any custom plugins that you might have added to your configuration.
