 A [connection pool](https://en.wikipedia.org/wiki/Connection_pool#:~:text=In%20software%20engineering%2C%20a%20connection,executing%20commands%20on%20a%20database.) is a storage of database connections that can be reused for future requests to the database. When a new connection is requested, it is retrieved from the pool if one is available. Once the connection is no longer needed, it is returned to the pool for reuse.
 
 [Connection pooling](https://www.prisma.io/dataguide/database-tools/connection-pooling) is important as it allows you to reuse existing connections instead of creating new ones, which can be an expensive operation.

 ### Default connection pool size
 
 By default, Accelerate calculates a default connection pool size using the formula `num_physical_cpus * 2 + 1`.

 ### Configuring the connection pool size
 
-The connection pool size can be configured to a value other than the default via the _database connection string_.
+The connection pool size can be configured via the _database connection string_ in your Platform project (_not_ the Accelerate connection string in your Prisma schema) via the `connection_limit` parameter. For example, set a connection pool size of `10` like this: `postgresql://USER:PASSWORD@HOST:PORT/DATABASE?connection_limit=10`.
 
-![Update database connection string in Accelerate](/img/accelerate/accelerate-update-database-connection-string.png)
+If nothing is configured, a default value will be used.
 
-To adjust the connection pool size, you can add the `connection_limit` parameter to the database connection string. The value of `connection_limit` is the maximum number of connections that Accelerate will open against your database.
+To change the size of the connection pool:
+1. Open the [Platform Console](https://console.prisma.io/).
+1. Select the _project_ in which you're using Accelerate. You might need to select a different _workspace_ if you can't see your project.
+1. Select the _environment_ where you want to configure Accelerate's connection pool size.
+1. Update the connection string by appending the `connection_limit` argument.

+## Overview
 
-Platform Console enables you to integrate the latest Prisma Data Platform products into your application
+The [Platform Console](http://console.prisma.io) enables you to manage and configure your projects that use Prisma Data Platform (PDP) products, and helps you integrate them into your application:
 
 - [Accelerate](/accelerate/what-is-accelerate): Global database cache with scalable connection pooling
 - [Pulse](/pulse/what-is-pulse): A managed Change Data Capture (CDC) service that enables real-time database subscriptions
 
-[Go to Platform Console](https://console.prisma.io)
 
-</TopBlock>
+## Concepts
+
+The Platform Console workflows are based on four main concepts:
+
+- [**User account**](#user-account): In order to use PDP products, you need to have a PDP user account. A _user_ will typically create one user account to manage all their workspaces, projects and environments. The _user_ can also be invited to join other workspaces to collaborate on the projects in that workspace.
+- [**Workspaces**](#workspace): A user account can belong to multiple workspaces. A workspace typically represents a _team_ of individuals working together on one or more projects. **Billing is on a workspace level**, i.e. the invoice for a workspace at the end of the month captures all costs associated with the projects in a given workspace.
+- [**Project**](#project): A project belongs to a workspace. It typically represents the _application_ or _service_ a team is working on.
+- [**Environments**](#environment): An environment belongs to a project. It typically maps to a _development stage_, like `dev`, `staging` or `prod`. **API keys are provisioned on the environment level**, and products are configured per environment as well (e.g. the database connection string used for Accelerate).
+
+Here is a visual illustration of how these concepts relate to each other:
+
+![](/img/platform/pdp-concepts.png)
+
+### User account
+
+A user account is the prerequisite for any interactions with PDP products. You can use it to manage your workspaces (and their projects). A user account can be invited to collaborate on workspaces created by other users as well.
+
+If you need to delete your user account, go [here](/platform/support#deleting-your-pdp-account).
+
+### Workspace
+
+You can create several workspaces. A workspace is an isolated space to host projects. A workspace can have multiple user accounts associated with it so that multiple users can collaborate on the the projects in the workspace.
+
+In each workspace, you can:
+
+- view and manage all projects (and their environments) in that workspace.
+- manage billing, i.e. select a [subscription plan](https://prisma.io/pricing?utm_source=prisma-docs&utm_medium=docs-site), configure payment methods, or view the invoice history.
+- view the usage of your enabled PDP products across all projects in that workspace.
+- manage team members and change their roles / permissions in the workspace.
+
+### Project
+
+In each workspace, you can create several projects. A project typically represents an application (a product or service). You typically have one [Prisma schema](/orm/prisma-schema/) per project.
+
+In each project, you can:
+
+- view and manage all environments in that project.
+
+The number of project you can create in a workspace depends on the [subscription plan](https://prisma.io/pricing?utm_source=prisma-docs&utm_medium=docs-site) configured in that workspace.
+
+### Environment
+
+An environment is an isolated space to provision PDP products for a given project. Environments typically map to development stages, like `dev`, `staging` or `prod`.
+
+In each environment, you can:
+
+- enable, disable and configure PDP products (Pulse, Accelerate, ...).
+- generate API keys.
+- for **Accelerate**:
+  - set your database connection string.
+  - configure the _region_ where Accelerate's connection pool is running.
+  - change the connection pool size.
+  - enable static IP.
+- for **Pulse**:
+  - set your database connection string (of a [Pulse-compatible database](/pulse/database-setup)).
+  - configure the _region_ where Pulse is running.
+  - configure database replication.
+
+The number of environments you can create in a project depends on the [subscription plan](https://prisma.io/pricing?utm_source=prisma-docs&utm_medium=docs-site) configured in your workspace.
+
+## Billing
+
+The [subscription plan](https://prisma.io/pricing?utm_source=prisma-docs&utm_medium=docs-site) you select in your workspace determins how many projects and environments you can create in that workspace:
+
+|                  | **Starter** | **Pro**     | **Business** | **Enterprise** |
+| ---------------- | :---------- | ----------- | ------------ | -------------- |
+| **Projects**     | 5           | 10          | 15           | Custom         |
+| **Environments** | 2 / project | 6 / project | 12 / project | Custom         |
+
+### Per-workspace billing
+
+Billing is set up on a per-workspace basis:
+
+- A subscription plan is selected per workspace. That means, a user account can belong to multiple workspaces where each workspace uses a different plan.
+- A payment method is selected per workspace. That means, a user account can belong to multiple workspaces where each workspace has a different payment method.
+
+At the end of a billing period, your selected payment method will be charged with the incurred costs of products across _all_ projects (and their environments) in that workspace.
+
+You can configure all billing details in the **Billing** section of your workspace.
+
+### Prorated billing
+
+All base plan prices are prorated, which means you're only billed for the duration of your subscription to a specific plan. In addition, you're also billed for any usage costs you've incurred during your subscription.
+
+For example:
+
+- if you subscribe to our **Pro** plan on the 15th day of a month, you'll only be charged the base plan price for the days left in that month.
+- if you downgrade your subscription plan (e.g. from **Business** to **Pro**) after 10 days of a 30-day month, you'll be charged for 10 days of the base price of the **Business** plan and 20 days for the base price of the **Pro** plan.
+
+Visit our [pricing page](https://prisma.io/pricing?utm_source=prisma-docs&utm_medium=docs-site) for more details.
+
+### Downgrading a subscription plan
+
+If you downgrade a subscription plan, you may need to delete some of your projects and/or their environments in order to adhere to the [limits](#environment) of the newly selected plan.
+
+For example, if your workspace is on a **Business** plan and currently has 14 (out of 15) projects, you will need to delete at least 4 projects to adhere to the project limit of the **Pro** plan. Additionally, you need to make sure that the remaining projects don't have more than 6 environments per project to adhere to the environment limit of the **Pro** plan.
+
+## Programmatic access via the Platform CLI
+
+In addition to the GUI of the Platform Console, the Prisma CLI provides another way to interact with your PDP account and manage PDP products in your projects.
+
+This can be useful if you need programmatic access, e.g. for integrating it into CI workflows.
+
+Read more about the [Prisma CLI](/platform/platform-cli).
+
+## API keys
+
+An API key is required to authenticate requests from your Prisma Client to products such as Prisma Accelerate and Prisma Pulse. You may generate multiple API keys per environment and manage those via the **API Keys** section in an environment.
