-The master branch of zig-clap targets the master branch of Zig. For a
-version of zig-clap that targets a specific Zig release, have a look
-at the releases. Each release specifies the Zig version it compiles with
-in the release notes.

 ## Installation
 
-First, run the following:
+Developers tend to either use
+* The latest tagged release of Zig
+* The latest build of Zigs master branch
 
-```
+Depending on which developer you are, you need to run different `zig fetch` commands:
+
+```sh
+# Version of zig-clap that works with a tagged release of Zig
+# Replace `<REPLACE ME>` with the version of zig-clap that you want to use
+# See: https://github.com/Hejsil/zig-clap/releases
+zig fetch --save https://github.com/Hejsil/zig-clap/archive/refs/tags/<REPLACE ME>.tar.gz
+
+# Version of zig-clap that works with latest build of Zigs master branch
 zig fetch --save git+https://github.com/Hejsil/zig-clap
 ```
