+## General
+### Update Houdini Vars on context change
+
+Allows admins to have a list of vars (e.g. JOB) with (dynamic) values that will be updated on context changes, e.g. when switching to another asset or task.
+
+Using template keys is supported but formatting keys capitalization variants is not, e.g. `{Asset}` and `{ASSET}` won't work
+
+
+:::note
+If `Treat as directory` toggle is activated, Ayon will consider the given value as a path of a folder.
+
+If the folder does not exist on the context change it will be created by this feature so that the path will always try to point to an existing folder.
+:::
+
+Disabling `Update Houdini vars on context change` feature will leave all Houdini vars unmanaged and thus no context update changes will occur.
+
+> If `$JOB` is present in the Houdini var list and has an empty value, Ayon will set its value to `$HIP`
+
+
+:::note
+For consistency reasons we always force all vars to be uppercase.
+e.g. `myvar` will be `MYVAR`

 ## Shelves Manager
+
+:::info
+Shelves manager is partially working, you can use **Shelf Set Path**, and is waiting for some bug fixes to be fully compatible with Ayon.

 You can add your custom [Shelves](https://www.sidefx.com/docs/houdini/shelf/index.html) into Houdini by setting your shelf sets, shelves and tools in **Houdini -> Shelves Manager**.

 The Shelf Set Path is used to load a .shelf file to generate your shelf set. If the path is specified, you don't have to set the shelves and tools.

+## FAQ
+
+### When will we need to modify Houdini addon code ?
+We've spent a lot of time making it possible to customize Houdini addon from settings.
+e.g. you can add your studio's menus, tools and digital assets from settings. 
+
+Still, you may need to modify Ayon addons only when :  
+- Adding/Modifying/Customizing Launch Hooks
+- Registering new Callbacks
+- Adding/Modifying/Customizing plugins (create, publish, load, Actions)
+- Adding a new Ayon launcher tray tool
+
+### How to add my menus, tools and digital assets to Houdini ?
+Mostly, you'd only need to update Environment to share these tools with your team. 
+e.g., 
+- `PYTHONPATH` to add a custom python library path
+- `HOUDINI_MENU_PATH` to add a custom menu path
+- `HOUDINI_OTL_PATH` to add a custom digital assets path
+
+Ayon allows you to add environment variables as:
+1. Global environment variable (it wil be available for all DCCs)
+2. Application specific (it wil be available for a particular DCC)
+3. Application variant specific (it wil be available for a particular DCC version)
+4. Tool (it wil be available on demand per project per asset from project Editor)
+

+
+### How to publish lookdev from Houdini ? 
+
+Publishing and managing Lookdev in Houdini is within our plan.
+The current solution to publish materials is to use HDAs as you can publish most of Houdini nodes as hda.
+
+### How to submit houdini patch version to deadline ?
+
+The custom AYON Deadline `GlobalJobPreLoad` functionality can help with that by adding the application specific environment variables before the job starts rendering. Using that we can point the Deadline Houdini plugin to e.g. just `houdini` for Deadline to find the executable by name instead of full path. To ensure it's found we just need to make sure the executable is available on the `PATH` environment variable. Like so:
+- update Houdini deadline config
+  ![faq-deadline-config](assets/houdini/admin/faq-deadline-config.png)
+- add Houdini dir to `PATH` environment variable and add `HOUDINI_VERSION` for each variant
