+# Development
+
+These are internal notes for the development of the project.
+
+## Installation
+
+Install dependencies
+
+```bash
+pnpm i
+```
+
+Setup environment correctly
+
+```bash
+cp .env.example .env
+```
+
+Look in the usual place for the relevant variables.
+
+## Running tests
+
+Before running tests, make sure you load the environment variables from the `.env` file.
+
+```bash
+source .env
+```
+
+> [!NOTE]
+> This is only necessary because I cannot for the life of me find out how to load the environment variables from the `.env` file in the `jest.config.ts` file.
+
+Then, to run the tests, run
+
+```bash
+pnpm test
+```
+
+## Publishing
+
+Just run
+
+```bash
+pnpm publish
+```
+
+This will create a new release in the `changeset` package.
