 There are a couple of good use cases to install custom bindists:
 
 1. manually built bindists (e.g. with patches)
-  - example: `ghcup install ghc -u 'file:///home/mearwald/tmp/ghc-eff-patches/ghc-8.10.2-x86_64-deb10-linux.tar.xz' 8.10.2-eff`

 3. DWARF bindists

 Since the version parser is pretty lax, `8.10.2-eff` and `head` are both valid versions
 and produce the binaries `ghc-8.10.2-eff` and `ghc-head` respectively.

 You need to use the `--isolate` or `-i` flag followed by the directory path.
 
-Examples:-
+Examples:
 
 1. install an isolated GHC version at location /home/user/isolated_dir/ghc/  
-   - `ghcup install ghc 8.10.5 --isolate /home/user/isolated_dir/ghc`
+    - `ghcup install ghc 8.10.5 --isolate /home/user/isolated_dir/ghc`
