 # Traction
 
-## Work In Progress
+## What is Traction
+
+[Traction](https://github.com/bcgov/traction) is an application built on top of [Aries Cloudagent Python](https://github.com/hyperledger/aries-cloudagent-python) to facilitate the provisioning and management of tenant agents. With Traction, the DITP team does not need to prepare and deploy new agent instances for each adopter: users submit a request for a tenant and are able to self check-in and manage their settings when approved.
+
+## Tenants
+
+A tenant is a "resident" of Traction: similar to occupants of a condominium, different entities/organizations access the same resources, but remain isolated and independent.
+
+There are several instances of Traction that can be used for different purposes:
+
+- [Sandbox](https://traction-sandbox-tenant-ui.apps.silver.devops.gov.bc.ca): this instance is completely self-serve and can be used for prototyping and discovery of short-lived projects. The sandbox is reset automatically, on the 1st and 15th day of the month.
+- [Development](https://traction-tenant-ui-dev.apps.silver.devops.gov.bc.ca): this instance would be the first step after prototyping in the `sandbox` and requires a request to be created in-app and reviewed by the DITP team.
+- [Test](https://traction-tenant-ui.apps.silver.devops.gov.bc.ca) and [Production](https://traction-tenant-ui.apps.silver.devops.gov.bc.ca) access can be requested the same way as for `development`, once the integration is ready to move further.
+
+A Traction tenant provides full access to an Aries agent connected to pre-approved [ledgers](#ledgers), however the functionality to become `issuers` is not enabled by default: a request outlining the business case/requirement to become an issuer should be submitted to DITP when the tenant request is initially created, or any time after that when integrating with credential issuance processes becomes necessary.
+
+More information about becoming an issuer can be found [here](traction-becoming-an-issuer.md).
+
+## Ledgers
+
+Traction is connected to several ledgers in read mode, which allows teh tenant to receive, present and verify credentials from issuers rooted on those ledgers - if necessary. In general, the `development` ledger can also read from `test` and `production` ledgers and the `test` environment can also read from `production`. The `production` environment is limited to production ledgers for security reasons.
+
+Each environment can also connects in write mode - for tenants who become issuers - to ledgers that are of the same level.
+
+!!! info "Info"
+Please note that an issuer can only ever connect to ONE ledger in write mode and that "moving" to another ledger is generally not recommended or supported at this time.
