+Plugins:
+----------
+
+Command: :set packpath
+
+    To see all the path vim will search for plugins.
+
+--> Where Packages are stored:
+
+    {packpath}/pack/{package-name}
+
+    Examples:
+    /home/junet/.vim/pack/git-plugins
+    /home/junet/.vim/pack/myplugins
+
+    {packpath}/pack/{package-name}/start/{plugin-name}
+    
+        To load a package along with all the plugins automatically when
+        vim starts. Use start/ directory inside package-directory.
+
+    
+    {packpath}/pack/{package-name}/opt/{plugin-name}
+
+        To not load automatically, but remain available to load
+        during vim runtime.
+        
+        To load a plugin in opt/ directory. Use command:
+
+        :packadd {plugin-directory-name}
+
+
+        For example:
+
+            :packadd vim-fugitive
+
+        This searches for "pack/*/opt/vim-fugitive" in the packpath.
+        Example: ~/.vim/pack/git-plugins/opt/vim-fugitive
