+zvm-direnv
+==========
+
+A way to use [zvm](https://zvm.app) with [direnv](https://direnv.net)
+
+Installing
+----------
+
+Put the following lines in your `.envrc`:
+
+```sh
+if ! has zvm_direnv_version || ! zvm_direnv_version 1.0.0; then
+  source_url "https://git.lerch.org/lobo/zvm-direnv/1.0.0/direnvrc" #"sha256-RuwIS+QKFj/T9M2TFXScjBsLR6V3A17YVoEW/Q6AZ1w="
+fi
+```
+
+Usage
+-----
+
+```sh
+$ echo "use zig 0.13.0" >> .envrc
+$ direnv allow
+```
+
+If you haven't used direnv before, make sure to [hook it into your shell](https://direnv.net/docs/hook.html) first.
+
+How it works
+------------
+
+This implementation utilizes zvm for installation of both [zig](https://ziglang.org)
+and [zls](https://github.com/zigtools/zls). It avoids the use of `zvm use` as
+this will change the zig version system-wide, possibly resulting in some
+confusing behavior. Instead, it uses zvm to download the appropriate versions
+if necessary, then prepends the desired version to the path used in the direnv
+directory.
