+## FAQ
+
+**Is Prezto or oh-my-zsh supported in some way?** No, if you load them they
+will be treated like any other plugin. Remember that those two basically are
+just bundles of plugins, I recommend against using them because one should load
+the individual plugins through a plugin manager like antigen or antigen-hs.
+If there's anything inside those plugins that you want, just create a seperate
+repository for it [like I did][command-not-found].
+
+
+**Why do I get `No *.plugin.zsh file` error?** Because all zsh plugins
+should have that file. I want to enforce it so that people start following this convention.
+The easiest way is to just
+[fork the plugin you want](https://github.com/Tarrasch/pure/) and/or
+[make them change it](https://github.com/sindresorhus/pure/pull/73)
+If you're interested in some discussion about this, take a look at
+<https://github.com/Tarrasch/antigen-hs/issues/3> and
+<https://github.com/zsh-users/antigen/issues/23>.
+
+**What is the relationship of antigen-hs with antigen?** antigen-hs can achieve
+100% of antigen if the user is just willing to spend some time doing things
+right (like not using plugin bundles like oh-my-zsh). In reward they don't need
+to use software that is bloated. To be fair, many (including my good github
+friend @sharat87) might want to say that antigen is more featureful/convenient,
+not bloated. I'll let you choose side yourself. :)
+
+**What about the antigen commands like `theme` and others?** I do not found
+them useful or stable so I rather not have them. I rather rely on my own zsh fu
+when it comes to choirs like updating the repositories (nuking the
+`~/.antigen-hs` folder) than relying on some shaky commands of antigen.
+
+**Can I only source GitHub repositories?** At the moment yes, patches are very welcome! :)
+
+**Why not write it in pure zsh?**

+
+**Why Haskell?** I love it, and I found the Shelly plugin to work extremely
+well for this kind of tasks.
