 Features
 =========
-* Let's you open (preview) images in Vim!
+* Let's you open (preview) images in Vim!:
+  Image supported:
+    * .png
+    * .jpg
+    * .jpeg
+    * .webp
 * It's safe, never modifies the original image (unless you force write)
-
+* Adapted to work with python3 instead of python2
 
 Requirements
 ============
 * Vim with *python* support. You can verify if your Vim is compiled with python using:
 
   `vim --version | grep python`
 
-  If you see `+python`, your Vim has python support. If not, figure out how to get one.
+  If you see `+python`, your Vim has python support. If not, compile or install yourself
+  a vim with python support.
 
+  In arch:
+  ```
+  sudo pacman -S gvim
+  ```
+  In Debian based:
+
+  ```
+  sudo apt install vim-gtk
+  ```
+
+  It will install gvim which include vim with python support and a GTK application of vim.  
+  You will be asked to remove Vim, but relax, you will keep the option of use vim in terminal.
+
 * Also needs the Python library PIL. You can install PIL using `pip install Pillow`

 * [Pathogen](https://github.com/tpope/vim-pathogen)

 * [Vundle](https://github.com/gmarik/vundle)
-  * `Plugin 'ashisha/image.vim'`
+  * `Plugin 'Daniel1404/image.vim'`
+  Then reload your .vimrc file and Install the Plugin.
+
+  ```
+    :so ~/.vimrc
+    :PluginInstall
+  ```
 * [NeoBundle](https://github.com/Shougo/neobundle.vim)
-  * `NeoBundle 'ashisha/image.vim'`
+  * `NeoBundle 'Daniel1404/image.vim'`
 * Manual
-  * Copy image.vim into your `~/.vim/plugin/` directory
+  Copy image.vim into your `~/.vim/plugin/` directory
+  ```
+  git clone https://github.com/Daniel1404/image.vim
+  cd image.vim
+  cp image.vim ~/.vim/plugin/
+  ```
+
+Errors
+============
+Not an error but a deficit, it doesn't work well with image that are 
+full colored like Screenshots, because the plugin uses Ascii characters.
+
 
 Thank you!
