+## Why Pongo?
+
+MongoDB is a decent database, yet it has issues around [ACID-complaince](https://jepsen.io/analyses/mongodb-4.2.6) and [licensing](https://www.percona.com/blog/is-mongodb-open-source), which can cause hardship for project scenarios and organisation policies.
+
+**Pongo brings the [PostgreSQL shape-shifting capabilities](https://www.amazingcto.com/postgres-for-everything/) to:**
+
+- benefit from **strong consistency** by using battle-tested and widely used PostgreSQL ACID-compliant database,
+- **easier integration** with other parts of your system using PostgreSQL,
+- **reuse your muscle memory from MongoDB** using compatible API. It will allow easier migration of existing projects,
+- **cut boilerplate** and easier nested data management than traditional relational tables,
+- operate **easier than crafting native PostgreSQL JSON queries**. They're powerful but not the most accessible,
+- get **performance boost** with [JSONB indexing capabilities](https://pganalyze.com/blog/gin-index#postgresql-jsonb-and-gin-indexes),
+- **benefit from PostgreSQL advanced capabilities** like [partitioning](https://www.postgresql.fastware.com/postgresql-insider-prt-ove), [logical replication](https://event-driven.io/en/push_based_outbox_pattern_with_postgres_logical_replication/) and [other PostgreSQL superpowers](https://event-driven.io/en/postgres_superpowers/)
+- **seamless integration with Cloud RDSes** and solutions like [CockroachDB](https://www.cockroachlabs.com/docs/stable/why-cockroachdb), [Supabase](https://supabase.com/), [Vercel Postgres](https://vercel.com/docs/storage/vercel-postgres).

+## Storage
 
 **The binary format of PostgreSQL JSONB means that data is pre-parsed, allowing faster read and write operations than text-based JSON.** You don't have to re-parse the data every time you query it, which saves processing time and improves overall performance. Additionally, JSONB supports advanced indexing options like GIN and GiST indexes, making searches within JSONB documents much quicker and more efficient.

 ## Is Pongo an ORM?
 
-It's not. It's focused on effective handling of the document data specifics. Node.js ORMs have capabilities to handle JSONB, e.g. DrizzleORM has good support for that for basic operations. Yet, they're all but limited to querying, usually for advanced ones you need to fallback to JSONPath or JSONB functions (so raw SQL). As you saw above, this syntax is not super pleasant to deal with. That's why Pongo aims to do it for you.

+
+## How is it different than FerretDB?
+
+FerretDB plugs into the native MongoDB protocol, which allows it to be used as MongoDB and connect to tools like Mongo UI, etc. Yet, it [requires running a proxy](https://docs.ferretdb.io/quickstart-guide/docker/).
+
+**Pongo operates on a different layer, translating the MongoDB API directly into SQL in the library code.** This can allow easier serverless integrations, such as sharing a connection pool with other PostgreSQL-based tools, etc. Of course, it won't allow using native tools based on the MongoDB network protocol.
+
+Pongo's goal is not to replace Mongo but to reuse its muscle memory and bring the PostgreSQL capabilities and superpowers into the Node.js land.
 
 ## Is it production ready?
 
 What's there is safe to use, but it's far from being 100% compliant with MongoDB. Pongo is a fresh project, so some stuff can be missing.
