+**Prerequisite**: Ironbug v1.0 and above only works with the new Ladybug Tools (not the legacy version). It is suggested to use the [Pollination installer](https://www.pollination.cloud/grasshopper-plugin) to install the Ladybug Tools, which comes with all compatible libraries and engines.
 
+1. Download the Ironbug [single-click installer](https://github.com/MingboPeng/Ironbug/releases) and execute it with admin privilege.
+
+2. The installer will auto-select the valid Ladybug Tools' installation folder, and install the Ironbug to its `grasshopper\ironbug` folder.

+
+3. Finish the installation and enjoy!
+
+Note: installing the Ironbug with the new single-click installer will automatically remove the old Ironbug (if any) from `C:\Ironbug`.
+
+## Installation Issues:
+
+### 1. Ironbug can't find the OpenStudio:
+Ironbug only uses the OpenStudio that is installed to the Ladybug Tools installation folder. If you use the Pollination installer to install Ladybug Tools, the OpenStudio is installed to `C:\Program Files\ladybug_tools\openstudio`. The easiest way to fix this issue is to use the [Pollination installer](https://www.pollination.cloud/grasshopper-plugin) to install the LBT plugins.
+
+### 2. Single-click installer can't find the Ladybug Tools' installation folder
+It is likely you installed the LBT from Food4Rhino, or installed to LBT to a non-standard location that Ironbug's installer can't find it. The following two directories are checked by the installer to find the Ladybug Tools' installation folder:
+
+    1. C:\Program Files\ladybug_tools\
+    2. C:\Users\USERNAME\ladybug_tools\
+
+The easiest way to fix this issue is to use the [Pollination installer](https://www.pollination.cloud/grasshopper-plugin) to install the LBT plugins.
+
+If you really have to install the Ladybug Tools to a customized directory, for example `D:\ladybug_tools`, you will have to manually point the Ironbug's installer the correct Ladybug Tools folder. In this case, the installation path will be `D:\ladybug_tools\grasshopper\ironbug`
