-## Epoch IDE
-
-There are multiple options available for installing Epoch as listed below. See the handbook for usage instructions.
-
-### Install Script
-
-Run the following command in your terminal to install the latest release (on Windows, use WSL):
-
-```
-curl -Ls https://install.lf-lang.org | bash -s epoch
-```
-
-You can also install the nightly pre-release:
-```
-curl -Ls https://install.lf-lang.org | bash -s epoch nightly
-```
-
-You can use the `--prefix=<path>` argument to change the default install location.
-
-The default prefix is `/usr/local/bin` on a Mac and `~/.local/bin` on Linux and WSL. You may not have write access to this directory by default, in which case, if you still want to use the default prefix, you can replace `sh` with `sudo sh` in the above commands.

-
-```
-yay -S epoch-bin
