 ### Before going through anything from here, make sure you have read through [Lua basics guide for GMod here](https://wiki.facepunch.com/gmod/Beginner_Tutorial_Intro) first!
 
 ## List of contents:
+- [Frequently Asked Questions](faq/FOR_USERS.md) - Answers to common base users questions
 - [Weapon Template](lua/tfa/documentation/tfa_base_template.lua) - reference for the main weapon Lua file with all values ([legacy template](lua/tfa/documentation/tfa_legacy_template.lua) is available for backwards compatibility reference)
 - [Melee Weapon Template](lua/tfa/documentation/tfa_melee_template.lua) - reference for melee-type weapons
 - [Attachment Template](lua/tfa/documentation/tfa_attachment_template.lua) - file name is the ID of attachment that goes into `SWEP.Attachments` table, place to `<your addon>/lua/tfa/att` folder
 - [Animations Reference](lua/tfa/documentation/tfa_anims_template.lua) - list of animations that are used by the base
 - [Custom Hooks](lua/tfa/documentation/tfa_hooks_custom.lua) - list of [hooks](https://wiki.facepunch.com/gmod/hook.Add) added by the base for the addons intercompatibility
+- [Developer FAQ](faq/FOR_DEVELOPERS.md) - Common code stuff relevant to developing TFA Base addons
 
 ## Paths that are loaded by the base automatically (in load order):
 - `lua/tfa/enums/` - Early enums initialization (only recommended for early global variables declaration)

+# Frequently Asked Questions/Useful Stuff for Addon Developers
+
+## Changing stats in `SWEP.Primary`/`SWEP.Secondary` tables does not work!
+Due to extensive stat caching system, you would need to override the base table values and clear the stat cache:
+1. Change value in `Primary_TFA` or `Secondary_TFA` table respectively
+```Lua
+wep.Primary_TFA.Damage = 123
+```
+2. Call `SWEP:ClearStatCache` function with the stat name
+```Lua
+wep:ClearStatCache("Primary.Damage")
+```
+This example sets base `SWEP.Primary.Damage` value to 123 and applies all necessary modifications to it through attachments/hooks
+
+## How to properly override base functions?
+If you are thinking of copying the function and modifying it, don't! This could (and will) break a lot of stuff after base update when said function is modified.
+What you should do instead is override with calling functions from base class:
+```Lua
+-- Example override function with return value
+DEFINE_BASECLASS(SWEP.Base) -- required only once before ALL override functions
+
+function SWEP:Think2(...)
+    local retVal = BaseClass.Think2(self, ...) -- running base method first
+
+    -- your code here
+
+    return retVal
+end
+```

+# Frequently Asked Questions
+
+## Weapons are not making any sounds, is something broken?
+If there are no additional errors, this is not related to any TFA addons or any other addon at all. You most likely have pirated CS:S, HL2 EP1/2 content installed, which breaks any custom sounds added by addons. Make sure to uninstall any of it first!
+If there are errors produced each time: Make sure the error is produced by the base and not the weapon you are using before reporting the issue.
+
+## How do I lock X attachment on my server?
+You can only disable attachments completely (`Q` -> `Utilities` -> `Server` -> `Enable Attachments` or `sv_tfa_attachments_enabled 0`.) There will never be an option for selective attachments blacklist included in the base.
+
+If you are an addon developer, the base is providing a hook that enables to disallow equipping attachments. The documentation on base hooks is available [here](lua/tfa/documentation/tfa_hooks_custom.lua).
+
+## The C-menu (inspection screen) is not working!
+Copy the following line and run it in the console:
+```
+sv_tfa_attachments_enabled 1; sv_tfa_cmenu 1; sv_tfa_cmenu_key -1; cl_tfa_keys_customize 0
+```
+
+## What's the console commands list?
+If you are using Sandbox or Sandbox-derived gamemode, you can use the `Server` settings menu in the `Utilities` tab to tweak the base to your liking (even on the server, the menu is networked!)
+
+For gamemodes without Sandbox spawnmenu, the console parameters list will be provided ~~soon shortly~~ sometime later. As for now, you can use `cvarlist cl_tfa_` on client and `cvarlist sv_tfa_` on the server to list all registered variables.
+
+## (Screenshot showing a bunch of errors from the base)
+You probably have some reupload (or any kind of server content that bundles the code) installed alongside the official version of the base. __Make sure you only have official version of the base installed and enabled first__ (try disabling all addons, enable only the base and weapons you are using then enable addons in halves until you find the one that's causing the issues)
+
+Alternatively, (although highly unlikely) you might have too many addons installed and enabled to actually hit the Lua files limit, which causes parts of the base simply to not load properly.
+
+## Server settings are reset after server restart!
+This is a problem with your server host. Base settings use default engine ConVars, which require `garrysmod/cfg/server.vdf` file to be writable to be saved correctly. Raise an issue to your server host if that file is read-only, as it breaks settings from other addons as well, not just TFA Base.
+
+## I have a problem with a Star Wars weapon/pack...
+**Contact author(s) of the said pack, not us.** We are unable to help with all kinds of issues coming from third-party weapons/packs. Consult the server rules __before__ posting your issue.
+
+## I can't select any attachment
+A. Remove `-tools` parameter from your GMod launch options. Engine tools interfere with `gui.EnableScreenClicker` function which is used by many addons (not just TFA Base and TFA-VOX) and are not needed in normal gameplay.
