+Plutus simple model
+====================================================
+
+Unit test library for Plutus with estimation of resource usage.
+
+Library defines simple mock model of Blockchain to unit test plutus contracts
+and estimate usage of resources. What are the benefits for this framework comparing
+to other test frameworks for Plutus? It's:
+
+* easy to use
+* easy to think about
+* it has minimal dependency set. It depends only on plutus and cardano-ledger.
+    Ain't no plutus-apps or cardano-node or ouroboros
+* works for both Plutus V1 and Plutus V2
+* support for Alonzo and Babbage eras
+* blazing fast
+* can estimate usage of resources with real functions used on Cardano node.
+* pure
+* good for unit testing of on-chain code
+* being fast and pure it's also suitable for property based testing
+
+## Quick start guide
+
+See [user guide](https://mlabs-haskell.github.io/plutus-simple-model/) to get started
+
+## How to compile the library
+
+Library is compiled with nix, flakes and cabal. Enter developer nix shell with:
+
+```
+nix develop
+```
+
+Inside the nix shell we can run build and tests over make:
+
+```
+make build
+make test
+```
+
+It calls cabal under the hood.
+
+## How to update docs
+
+Docs are written in [mdbook](https://github.com/rust-lang/mdBook) and reside in the `docs` directory.
+They are auto-deployed with Git actions on push to main. To run docs locally use mdbook:
+
+```
+cd docs
+mdbook serve
+```

+Plutus simple model
+====================================================
+
+Unit test library for Plutus with estimation of resource usage.
+
+Library defines simple mock model of Blockchain to unit test plutus contracts
+and estimate usage of resources. What are the benefits for this framework comparing
+to other test frameworks for Plutus? It's:
+
+* easy to use
+* easy to think about
+* it has minimal dependency set. It depends only on plutus and cardano-ledger.
+    Ain't no plutus-apps or cardano-node or ouroboros
+* works for both Plutus V1 and Plutus V2
+* support for Alonzo and Babbage eras
+* blazing fast
+* can estimate usage of resources with real functions used on Cardano node.
+* pure
+* good for unit testing of on-chain code
+* being fast and pure it's also suitable for property based testing
+
+## Quick start guide
+
+See [user guide](https://mlabs-haskell.github.io/plutus-simple-model/) to get started
+
+## How to compile the library
+
+Library is compiled with nix, flakes and cabal. Enter developer nix shell with:
+
+```
+nix develop
+```
+
+Inside the nix shell we can run build and tests over make:
+
+```
+make build
+make test
+```
+
+It calls cabal under the hood.
+
+## How to update docs
+
+Docs are written in [mdbook](https://github.com/rust-lang/mdBook) and reside in the `docs` directory.
+They are auto-deployed with Git actions on push to main. To run docs locally use mdbook:
+
+```
+cd docs
+mdbook serve
+```
