+## Getting Help
 
-Thank you for your interest in contributing to NetBox! This document contains some quick pointers on reporting bugs and
-requesting new features.
+If you encounter any issues installing or using NetBox, try one of the following resources to get assistance. Please
+**do not** open an issue on GitHub except to report bugs or request features.
 
-## Reporting Issues
+### Freenode IRC
 
-* First, ensure that you've installed the latest stable version of NetBox. If you're running an older version, it's
-possible that the bug has already been fixed.
+Join the #netbox channel on [Freenode IRC](https://freenode.net/). You can connect to Freenode at irc.freenode.net using
+an IRC client, or you can use their [webchat client](https://webchat.freenode.net/).
 
-* Check the [issues list](https://github.com/digitalocean/netbox/issues) to see if the bug you've found has already been
-reported. If you think you may be experiencing a reported issue, please add a quick comment to it with a "+1" and a
-quick description of how it's affecting your installation.

-* If you're unsure whether the behavior you're seeing is expected, you can join #netbox on irc.freenode.net and ask

 NetBox is an IP address management (IPAM) and data center infrastructure management (DCIM) tool. Initially conceived by the network engineering team at [DigitalOcean](https://www.digitalocean.com/), NetBox was developed specifically to address the needs of network and infrastructure engineers.
 
 NetBox runs as a web application atop the [Django](https://www.djangoproject.com/) Python framework with a [PostgreSQL](http://www.postgresql.org/) database. For a complete list of requirements, see `requirements.txt`. The code is available [on GitHub](https://github.com/digitalocean/netbox).

+This is a list of valid fully-qualified domain names (FQDNs) that is used to reach the NetBox service. Usually this is the same as the hostname for the NetBox server, but can also be different (e.g. when using a reverse proxy serving the NetBox website under a different FQDN than the hostname of the NetBox server). NetBox will not permit access to the server via any other hostnames (or IPs). The value of this option is also used to set `CSRF_TRUSTED_ORIGINS`, which restricts `HTTP POST` to the same set of hosts (more about this [here](https://docs.djangoproject.com/en/1.9/ref/settings/#std:setting-CSRF_TRUSTED_ORIGINS)). Keep in mind that NetBox, by default, has `USE_X_FORWARDED_HOST = True` (in `netbox/netbox/settings.py`) which means that if you're using a reverse proxy, it's the FQDN used to reach that reverse proxy which needs to be in this list (more about this [here](https://docs.djangoproject.com/en/1.9/ref/settings/#allowed-hosts)).

Each rack has two faces (front and rear) on which devices can be mounted.
 
 Each rack is assigned a name and (optionally) a separate facility ID. This is helpful when leasing space in a data center your organization does not own: The facility will often assign a seemingly arbitrary ID to a rack (for example, M204.313) whereas internally you refer to is simply as "R113." The facility ID can alternatively be used to store a rack's serial number.
 
+The available rack types include 2- and 4-post frames, 4-post cabinet, and wall-mounted frame and cabinet. Rail-to-rail width may be 19 or 23 inches.

 ### Rack Groups
 
 Racks can be arranged into groups. As with sites, how you choose to designate rack groups will depend on the nature of your organization. For example, if each site is a campus, each group might be a building. If each site is a building, each rack group might be a floor or room.

+
+# Custom Fields
+
+Each object in NetBox is represented in the database as a discrete table, and each attribute of an object exists as a column within its table. For example, sites are stored in the `dcim_site` table, which has columns named `name`, `facility`, `physical_address` and so on. As new attributes are added to objects throughout the development of NetBox, tables are expanded to include new rows.
+
+However, some users might want to associate with objects attributes that are somewhat esoteric in nature, and that would not make sense to include in the core NetBox database schema. For instance, suppose your organization needs to associate each device with a ticket number pointing to the support ticket that was opened to have it installed. This is certainly a legitimate use for NetBox, but it's perhaps not a common enough need to warrant expanding the internal data schema. Instead, you can create a custom field to hold this data.
+
+Custom fields must be created through the admin UI under Extras > Custom Fields. To create a new custom field, select the object(s) to which you want it to apply, and the type of field it will be. NetBox supports six field types:
+
+* Free-form text (up to 255 characters)
+* Integer
+* Boolean (true/false)
+* Date
+* URL
+* Selection
+
+Assign the field a name. This should be a simple database-friendly string, e.g. `tps_report`. You may optionally assign the field a human-friendly label (e.g. "TPS report") as well; the label will be displayed on forms. If a description is provided, it will appear beneath the field in a form.
+
+Marking the field as required will require the user to provide a value for the field when creating a new object or when saving an existing object. A default value for the field may also be provided. Use "true" or "false" for boolean fields. (The default value has no effect for selection fields.)
+
+When creating a selection field, you should create at least two choices. These choices will be arranged first by weight, with lower weights appearing higher in the list, and then alphabetically.
+
+## Using Custom Fields
+
+When a single object is edited, the form will include any custom fields which have been defined for the object type. These fields are included in the "Custom Fields" panel. On the backend, each custom field value is saved separately from the core object as an independent database call, so it's best to avoid adding too many custom fields per object.
+
+When editing multiple objects, custom field values are saved in bulk. There is no significant difference in overhead when saving a custom field value for 100 objects versus one object. However, the bulk operation must be performed separately for each custom field.
 
 # Export Templates

 Export templates are written in [Django's template language](https://docs.djangoproject.com/en/1.9/ref/templates/language/), which is very similar to Jinja2. The list of objects returned from the database is stored in the `queryset` variable. Typically, you'll want to iterate through this list using a for loop.
 
+To access custom fields of an object within a template, use the `cf` attribute. For example, `{{ obj.cf.color }}` will return the value (if any) for a custom field named `color` on `obj`.
