# Lead streams
How to create lead streams — rule sets that automatically deliver Marketing Qualified Leads to a sales team when contacts match the criteria.
A lead stream is a set of rules that generates Marketing Qualified Leads (MQL) for Sales to process.
Whenever a contact matches the rules of a lead stream, the contact becomes a lead and is delivered to a chosen sales team. Once set up, a lead stream delivers leads continuously.
## Create a lead stream
Open the lead board by clicking Leads in the left sidebar.
To set up a new lead stream, click the Manage lead streams icon next to the lead streams drop-down.
This opens Lead Streams in Account Settings, where you can create or manage lead streams.
Click Add Lead Stream to create a new one.
A lead stream needs three things:
* A name and an optional description
* A set of filter rules
* One or more sales teams to deliver leads to
### Add a new rule
Click Add New Rule, name the rule, and choose a condition category — for example Score — to add the first criterion for becoming a lead.
In this scenario we want to find contacts with high lead scores.
Click Apply to add the rule. Add other rules to expand or narrow which contacts qualify as leads.
### Choose a sales team
Under Distribution to Sales Team, check one or more sales teams that should have access to this lead stream.
### Enable the new lead stream
You have the following options on a new lead stream:
* Enabled / Disabled — a new lead stream starts inactive. Toggle the switch to Active and click Save Changes to set it live. From that moment, any new matches to your rules generate leads.
* Clear leads — you can clear the lead stream of all leads at any time. This removes the leads from the lead board that match this stream. The stream must be inactive for this option to be available.
* Fetch history — a lead stream only generates leads from new matches. For example, if you want to make leads from contacts who answer a form, the stream generates leads only from form submits that come in while the stream is active. To make leads from past matches, click "Fetch ALL leads from history" to generate the historical leads once. The stream must be active for this option to be available.
## Check the results
Head back to the lead board to see the new leads.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://support.emarketeer.com/guides/lead-board-scoring/lead-streams.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
