+There are currently two configuration options for setting up disk space management on the SDK currently. This small guide should help clarifying what they mean.
+
+For using them, just set [using the settings_set api](https://lbry.tech/api/sdk#settings_set) or `daemon_settings.yaml` file.
+
+## Relevant configuration keys
+### network_storage_limit
+Default: 0
+
+Disk space in megabytes to be allocated for helping the P2P network with background downloads and seeding. The way it works is explained in a section below.
+Setting it to 0 disables background downloading.
+
+### blob_storage_limit
+Default: 0
+
+Disk space in megabytes to be allocated for downloads and streams during normal usage of the SDK.
+
+Setting it to 0 disables disk space management for files (or make it unlimited in other words).
+
+## What happens when the limit is reached?
+
+There are plans for better space management policies, but for now we delete the oldest data. When that changes, this section will be updated.
+
+## What does helping the P2P network means?
+When you allocate space for helping the P2P network, your SDK instance will listen for DHT requests and re-host content as they are being requested, until the allocated space is full. Then it will announce and keep serving that content to other peers.
+This data won't pollute your library, show up in file list or require manual intervention. Everything happens automatically.
+
+Seeding also happens naturally to normal files, this won't replace or disable previous behavior.
