+## What is Cap?
+
+Cap is the open source alternative to Loom. Lightweight, powerful, and cross-platform. Record and share in seconds.
+
+## How to self-host
+
+There are two storage options: you can store the video data on a remote storage service like S3 or R2, or you can choose the less recommended option of storing it directly on the local VPS (or another VPS) via a MinIO service.
+
+### Option 1: Remote S3-compatible storage (AWS S3, Cloudflare R2, etc.)
+
+Set these environment variables:
+
+- `CAP_AWS_ACCESS_KEY`: Your S3/R2 access key
+- `CAP_AWS_SECRET_KEY`: Your S3/R2 secret key
+- `CAP_AWS_BUCKET`: Your S3/R2 bucket name
+- `CAP_AWS_REGION`: Your S3/R2 region (e.g., us-east-1, auto for R2)
+- `CAP_AWS_ENDPOINT`: Your S3/R2 endpoint URL
+- `S3_PUBLIC_ENDPOINT`: Public endpoint for your bucket (same as CAP_AWS_ENDPOINT for most cases)
+- `S3_INTERNAL_ENDPOINT`: Internal endpoint (same as CAP_AWS_ENDPOINT for most cases)
+- `S3_PATH_STYLE`: true for R2/most S3-compatible, false for AWS S3 virtual-hosted style
+
+### Option 2: Local MinIO storage
+
+Deploy MinIO as a separate service in the same network and set:
+
+- `CAP_AWS_ACCESS_KEY`: MinIO root user
+- `CAP_AWS_SECRET_KEY`: MinIO root password
+- `CAP_AWS_BUCKET`: Your bucket name (e.g., capso)
+- `CAP_AWS_REGION`: us-east-1 (or any region)
+- `CAP_AWS_ENDPOINT`: http://minio:9000 (internal MinIO endpoint)
+- `S3_PUBLIC_ENDPOINT`: http://your-minio-domain:9000 (public MinIO endpoint)
+- `S3_INTERNAL_ENDPOINT`: http://minio:9000 (internal MinIO endpoint)
+- `S3_PATH_STYLE`: true
+
+## Email Login Links
+
+If the `RESEND_API_KEY` and `RESEND_FROM_DOMAIN` environment variables are not set, login links will be written to the server logs. To send login links via email, you'll need to configure [Resend](https://resend.com):
+
+1. Create an account at [Resend](https://resend.com)
+2. Connect a domain and set it as `RESEND_FROM_DOMAIN`
+3. Generate an API key and set it as `RESEND_API_KEY`
+
+## How to unlock limits (organization seats and recordings)
+
+<!--Method recommended from https://github.com/coollabsio/coolify/pull/6011#pullrequestreview-3337020957-->
+1. Open the terminal of the MySQL service
+2. Connect to the database: `mysql -u root -p planetscale` and use the `MYSQL_ROOT_PASSWORD` when prompted
+3. Run the SQL command below, replacing `your-user-id` with your actual user ID
+    ```sql
+    UPDATE users SET inviteQuota = 100, stripeSubscriptionId = '12345', subscriptionStatus = 'active' WHERE id = 'your-user-id';
+    ```
+4. You can verify the changes by running the following command:
+    ```sql
+    SELECT * FROM users WHERE id = 'your-user-id';
+    ```
