+# Uncategorized Documentation
+
+Any document in this directory may be moved in the future to
+a more suitable location. This is a good place to put any
+documentation that needs to be written when it's unclear what
+the best place for it is. This is to avoid situations where
+documentation _doesn't_ get written simply because it's not clear
+where it belongs (something which the author of this very document
+has been guilty of at times).

+# Notes about ES6 Class Syntax
+
+## Document Meta
+
+> **backend focus:** This documentation is more relevant to
+> Puter's backend than frontend, but is placed here because
+> it could apply to other areas in the future.
+
+## Expressions as Methods
+
+One important shortcoming in the ES6 class syntax to be aware of
+is that it discourages the use of expressions as methods.
+
+For example:
+
+```javascript
+class ExampleClass extends SomeBase {
+    intuitive_method_definition () {}
+    
+    constructor () {
+        this.less_intuitive = some_expr();
+    }
+}
+```
+
+Even if it is known that the return type of `some_expr` is a function,
+it is still unclear whether it's being used as a callback or
+as a method without other context in the code, since this is
+how we typically assign instance members rather than methods.
+
+We solve this in Puter's backend using a **trait** called
+[AssignableMethodsTrait](../../packages/backend/src/traits/AssignableMethodsTrait.js)
+which allows a static member called `METHODS` to contain
+method definitions.
+
+### Uses for Expressions as Methods
+
+#### Method Composition
+
+Method Composition is the act of composing methods from other
+constituents. For example,
+[Sequence](../../packages/backend/src/codex/Sequence.js)
+allows composing a method from smaller functions, allowing
+easier definition of "in-betwewen-each" behaviors and ways
+to track which values from the arguments are actually read
+during a particular call.

+# Puter Mods
+
+## What is a Puter Mod?
+
+Currently, the definition of a Puter mod is:
+
+> A [Module](../../packages/backend/doc/contributors/modules.md)
+> which is exported by a package directory which itself exists
+> within a directory specified in the `mod_directories` array
+> in `config.json`.
+
+## Enabling Puter Mods
+
+### Step 1: Update Configuration
+
+First update the configuration (usually at `./volatile/config.json`
+or `/var/puter/config.json`) to specify mod directories.
+
+```json
+{
+    "config_name": "example config",
+
+    "mod_directories": [
+        "{source}/mods/mods_enabled"
+    ]
+
+    // ... other config options
+}
+```
+
+The first path you'll want to add is
+`"{source}/mods/mods_enabled"`
+which adds all the mods included in Puter's official repository.
+You don't need to change `{source}` unless your entry javascript
+file is in a different location than the default.
+
+If you want to enable all the mods, you can change the path above
+to `mods_available` instead and skip step 2 below.
+
+### Step 2: Select Mods
+
+To enable a Puter mod, create a symbolic link (AKA symlink) in
+`mods/mods_enabled`, pointing to
+a directory in `mods/mods_available`. This follows the same convention
+as managing sites/mods in Apache or Nginx servers.
+
+For example to enable KDMOD (which you can read as "Kernel Dev" mod,
+or "the mod that GitHub user KernelDeimos created to help with testing")
+you would run this command:
+```sh
+ln -rs ./mods/mods_available/kdmod ./mods/mods_enabled/
+```
+
+This will create a symlink at `./mods/mods_enabled/kdmod` pointing
+to the directory `./mods/mods_available/kdmod`.
+
+> **note:** here are some helpful tips for the `ln` command:
+> - You can remember `ln`'s first argument is the unaffected
+>   source file by remembering `cp` and `mv` are the same in
+>   this way.
+> - If you don't add `-s` you get a hard link. You will rarely
+>   find yourself needing to do that.
+> - The `-r` flag allows you to write both paths relative to
+>   the directory from which you are calling the command, which
+>   is sometimes more intuitive.
