+# iCalendar.vim 
+
+## Description
+This is a fork of the original script from Steven Severinghaus (https://github.com/vim-scripts/icalendar.vim)
+
+This is a very rudimentary syntax file for icalendar files (.ics), used by Apple's iCal, Mozilla's Sunbird, Google Calendar, and other software. 
+
+## Screenshots
+![screenshot](doc/icalendar_screenshot.png?raw=true)
+
+Here's a screenshot of the syntax highlighting using the "PaperColor" colorscheme.
+
+## Installation 
+You can install icalendar.vim in the usual way, by copying the contents of the plugin, autoload and doc directories into the equivalent directories inside the runtime directory (see `:version` to know where your system put vim runtime files).
+
+### Manual installation
+- Download the [zip file](https://github.com/antoniopaolini/icalendar.vim/archive/refs/heads/master.zip)
+- unzip it. 
+- Go to vim's user runtime directory (.vim/ or vimfiles\) and copy the content of the zip file into folders with the same name.
+
+### Plugin Manager
+
+#### Pathogen
+Alternatively, if you manage your plugins using **pathogen.vim**, you can simply clone into the bundle directory:
+
+Navigate to the vim's user runtime directory:
+- **Windows**: 
+	`cd %HOMEPATH%\vimfiles\bundle`
+- **UNIX (Linux, MacOS X, and others)**: 
+	`cd ~/.vim/bundle`
+
+Then clone the git repo.
+`git clone https://github.com/antoniopaolini/icalendar.vim.git`
+
+#### Others Plugin Manager
+
+If you use Vundle or another Vim package manager, you'll need to adjust the commands below to work with it.
+For example see Installation section of [this plugin](https://github.com/mattn/emmet-vim)
+
+## Version History
