-Run `osenv` like this:
+## Installation
+
+### Requirements
+
+- Rust + Cargo (tested w/ 1.37)
+- A compatible shell (powershell/bash/zsh)
+
+### Compilation
 
 ```sh
-eval $(osenv)
+cargo install --path .
 ```
+
+This will install `osenv-bin` in your cargo bin folder (don't forget to add it to `PATH`!)
+You can already use it, with some caveats (having to specify the full string, like `osenv-bin | iex`), but you should just make a function and add it to your shell's profile file.
+
+### Add to profile
+
+If you're using sh/bash/zsh, add this to your .bashrc/.zshrc/etc:
+
+```sh
+osenv() {
+    RES=$(osenv-bin $@)
+    if [ $? -eq 0 ]; then
+        eval $RES
+    else
+        echo $RES
+    fi
+}
+```
+
+If you're using Powershell, add this to your `$profile`:
+
+```ps1
+function osenv {
+    $cmd = osenv-bin @Args
+    if ($?) {
+        $cmd | Invoke-Expression
+    }
+    else {
+        Write-Output $cmd
+    }
+}
+```
+
+If you rather have them as script to source, you can find them in `scripts` in this repo.
+
+If you want to enhance osenv to add a special "add to profile" command, or make some scripts that do (easy in powershell, not so much in the shell world), contributions are highly appreciated!
