-### Download the compiler
 
-At this point Fe is only distributed via a single executable file linked from the [home page](https://fe-lang.org). In the future we will make sure it can be installed through popular package managers such as `apt` or `homebrew`.
+First run the command below to get fe compiler, and add fe compier to your PATH:
 
-Depending on your operating system, the file that you download is either named `fe_amd64` or `fe_mac`.
-
-> Note: We will rename the file to `fe` and assume that name for the rest of the guide. In the future when Fe can be installed via other mechanisms we can assume `fe` to become the canonical command name.
+```bash
+curl https://raw.githubusercontent.com/ethereum/fe/create-install-script/install.sh | sh
+```
 
-### Add permission to execute
+Check install successfuly 
+```
 
-In order to be able to execute the Fe compiler we will have to make the file *executable*. This can be done by navigating to the directory where the file is located and executing `chmod + x <filename>` (e.g. `chmod +x fe`).
+> fe
 
-After we have set the proper permissions we should be able to run `./fe_amd64 --help` or `./fe_mac -h` and an output that should be roughly comparable to:
