+## Use for different OS
+You can use tldr++ for another OS by setting `TLDR_OS` envrionment to your desired OS such as `linux`, `windows`, `osx` etc.
+
+Let's say you want to set it to Linux run the following command:
+
+```bash
+export TLDR_OS=linux
+```
+
+To make it permenant, you can add the line above to your shell rc file (e.g. `bashrc`, `zshrc` etc.)
