 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 to a value other than the default via the _database connection string_ in your PDP project (_not_ the connection string in the Prisma schema) via the `connection_limit` parameter. For example, to 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)
+To change the size of the connection pool:
+1. Open the [Platform Console](https://console.prisma.io/).
+1. Select the _workspace_ of the _project_ in which you're using Accelerate and navigate into that _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. 
 
-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.

+## Concepts
+
+The Platform Console workflows are based on four main concepts:
+
+- [**Account**](#account): In order to use PDP products, you need to have a PDP account. An _organization_ will typically create one account to manage all their workspaces, projects and environments.
+- [**Workspaces**](#workspace): An account can have multiple workspaces. A workspace typically represents a _team_ within an _organization_. **Billing happens on a per-workspace basis**, i.e. an _organization_ receives an invoice at the end of the month that captures all cost associated with the projects in a given workspace.
+- [**Project**](#project): A workspace can have multiple projects. A project typically represents the _application_ of a _product_ or _service_ a team is working on.
+- [**Environments**](#environment): A project can have multiple environments. An environment typically maps to a _development stage_, like `dev`, `staging` or `prod`. **API keys are provisioned on the environment-level**.
+
+Here is a visual illustration of how these concepts relate to each other:
+
+![](/img/platform/pdp-concepts.png)
+
+### Account
+
+Your account is the basis for all interactions with PDP products. You can use it to manage your workspaces (and their projects).
+
+If you need to delete your account, go [here](/platform/support#deleting-your-pdp-account).
+
+### Workspace
+
+In your PDP account, you can create several workspaces. A workspace is an isolated space to host projects in which you use PDP products.
+
+In each workspace, you can:
+
+- view and manage all projects (and their environments) in that workspace.
+- manage billing, i.e. select a [pricing plan](https://pris.ly/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) your organization is offering. 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 [pricing plan](https://pris.ly/pricing?utm_source=prisma-docs&utm_medium=docs-site) configured in that workspace:
+
+Here's an overview of the number of projects per workspace on each plan:
+
+|              | **Starter** | **Pro** | **Business** | **Enterprise** |
+| ------------ | ----------- | ------- | ------------ | -------------- |
+| **Projects** | 5           | 10      | 15           | Custom         |
+
+### 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 manage PDP products (Pulse, Accelerate, ...).
+- for **Accelerate**:
+  - set your database connection string.
+  - generate API keys.
+  - change the connection pool size.
+  - enable static IPs.
+- 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.
+  - generate API keys.
+
+The number of environments you can create in a project depends on the [pricing plan](https://pris.ly/pricing?utm_source=prisma-docs&utm_medium=docs-site) configured in your workspace:
+
+Here's an overview of the number of environments per project on each plan:
+
+|                  | **Starter** | **Pro**     | **Business** | **Enterprise** |
+| ---------------- | ----------- | ----------- | ------------ | -------------- |
+| **Environments** | 2 / project | 6 / project | 12 / project | Custom         |
+
+## Billing
+
+The [pricing plan](https://pris.ly/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 in PDP is done on a per-workspace basis:
+
+- A pricing plan is selected per workspace. That means, your PDP account can have multiple workspaces where each workspace uses a different pricing plan.
+- A payment method is selected per workspace. That means, your PDP account can have multiple workspaces where each workspace has a different payment method.
+
+At the end of the billing period, **your selected payment method will be charged with the usage costs of the PDP products across _all_ the projects (and their environments) in that workspace**.
+
+You can configure all billing details in the **Billing** section of your project.
+
+### Prorated billing
+
+All our paid plans are prorated, which means **you're only billed for the duration you use a specific plan**.
+
+For example:
+
+- if you subscribe to our **Pro** plan for only 15 days in a 30-day month, you'll only be charged for half of the plan's price.
+- if you want to try out a particular plan for only 2 days, you can do so and you'll only be charged for the respective fraction of the plan's price (2 days out of the entire month).
+- if you downgrade your pricing plan (e.g. from **Business** to **Pro**) after 10 days of a 30-day month, you'll be charged 1/3 (i.e. 10 days) for the **Business** plan and 2/3 (i.e. 20 days) for the **Pro** plan.
+
+Visit our [pricing page](https://pris.ly/pricing?utm_source=prisma-docs&utm_medium=docs-site) for more details.
+
+### Downgrading a pricing plan
+
+If you downgrade a pricing 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 current 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, thge Prisma CLI provides another way to interact with your PDP account and manage PDP products in your projects.
+
+This is if you need programmatic access to your account, e.g. for integrating it into CI workflows.
+
+Read more about the Prisma CLI [here](/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 a project.
