+# Language Specific Packages
+
+This section of the monorepo contains the language specific published packages which may or may not be built from shared rust code.
+
+## Installation
+
+Whilst we are building out the capabilities, we will likely be making a lot of breaking changes.
+As such we will only be releasing alpha versions of the packages for integration with internal tooling.
+At this point anything is open to change, so because of that we'll only publish these packages to internal package sources.
+
+See below for the installation instructions for each supported language:
+
+### Python
+
+The Python packages are published as wheels on the GitHub release. These can be installed directly.
+
+For a binary wheel with multiple target platforms like [algokit_transact](https://github.com/algorandfoundation/algokit-core/releases/tag/python%2Falgokit_transact%401.0.0-alpha.1), you can use the below config.
+
+```toml
+[tool.poetry.dependencies]
+algokit_transact = [
+    { url = "https://github.com/algorandfoundation/algokit-core/releases/download/python%2Falgokit_transact%401.0.0-alpha.1/algokit_transact-1.0.0a1-py3-none-macosx_10_12_x86_64.whl", markers = "sys_platform == 'darwin' and platform_machine == 'x86_64'" },
+    { url = "https://github.com/algorandfoundation/algokit-core/releases/download/python%2Falgokit_transact%401.0.0-alpha.1/algokit_transact-1.0.0a1-py3-none-macosx_11_0_arm64.whl", markers = "sys_platform == 'darwin' and platform_machine == 'arm64'" },
+    { url = "https://github.com/algorandfoundation/algokit-core/releases/download/python%2Falgokit_transact%401.0.0-alpha.1/algokit_transact-1.0.0a1-py3-none-manylinux_2_17_x86_64.manylinux2014_x86_64.whl", markers = "sys_platform == 'linux' and platform_machine == 'x86_64'" },
+    { url = "https://github.com/algorandfoundation/algokit-core/releases/download/python%2Falgokit_transact%401.0.0-alpha.1/algokit_transact-1.0.0a1-py3-none-manylinux_2_17_aarch64.manylinux2014_aarch64.whl", markers = "sys_platform == 'linux' and platform_machine == 'aarch64'" },
+    { url = "https://github.com/algorandfoundation/algokit-core/releases/download/python%2Falgokit_transact%401.0.0-alpha.1/algokit_transact-1.0.0a1-py3-none-win_amd64.whl", markers = "sys_platform == 'win32' and platform_machine == 'AMD64'" }
+]
+```
+
+For a non binary wheel like [algod_api](https://github.com/algorandfoundation/algokit-core/releases/tag/python%2Falgod_api%401.0.0-alpha.2), you can use the below config.
+
+```toml
+[tool.poetry.dependencies]
+algokit_algod_api = { url = "https://github.com/algorandfoundation/algokit-core/releases/download/python%2Falgod_api%401.0.0-alpha.2/algokit_algod_api-1.0.0a2-py3-none-any.whl" }
+```
+
+### TypeScript
+
+The TypeScript packages are published to the GitHub packages NPM repository.
+
+For example [algokit_transact](https://github.com/algorandfoundation/algokit-core/pkgs/npm/algokit-transact).
+
+GitHub packages (the product) has some constaints, namely:
+
+- It requires authentication to install a package
+- It enforce packages scopes, which must match the GitHub username (`algorandfoundation` in our case).
+
+Unfortunately for us, the package scope in GitHub packages matches the official NPM registry and NPM itself does not support configuring multiple registries for a single package scope, so we need to be a little crafty when installing/updating the alpha packages we're installing from GitHub packages.
+
+To install, follow the below:
+
+1. Create a new [personal access token](https://github.com/settings/tokens/new) with `read:packages` permission and your preference of expiration time.
+2. Add the following to `~/.npmrc`:
+
+   ```
+   @algorandfoundation:registry=https://npm.pkg.github.com
+   //npm.pkg.github.com/:_authToken={TOKEN}
+   ```
+
+3. Install the package hosted in GitHub packages, which will update your NPM package lock file.
+
+   ```
+   npm install @algorandfoundation/[email protected]
+   ```
+
+4. Remove `@algorandfoundation:registry=https://npm.pkg.github.com` from `~/.npmrc`, so NPM hosted `@algorandfoundation` packages can be resolved.
+
+Note: You will need to perform steps 2-4 each time your either install a package for the first time or update a GitHub package hosted dependency. Installing from the lock file only requires the token.
