+## Installation
+
+`envr` does not need to be installed, but it can be nice to add the alias `envr`
+to your shell profile, allowing you to activate the environment of the current
+directory with `envr` instead of `. ./envr.ps1`.
+
+### PowerShell
+```powershell
+Add-Content -Path $profile -Value "function envr { . ./envr.ps1 }"
+```
+
+### bash
+```bash
+echo "alias envr='. ./envr.ps1'" >> ~/.bashrc
+```
+
+### zsh
+```bash
+echo "alias envr='. ./envr.ps1'" >> ~/.zshrc
+```
