+## Merging Conflicts
+
+It is very likely that you will encounter merging conflicts when working with the repository.
+
+Generally speaking, when encountering conflicts on the following files, you need to accept *any of them* but make sure to re-generate them:
+1. pnpm-lock.yaml
+2. database.types.ts
+
+### pnpm-lock.yaml
+To fix the conflicts, you can run the following command:
+
+```bash
+pnpm i
+```
+
+1. The lock file will be regenerated according to the changes in the repository and your local changes.
+
+### Database Types
+For the database types, reset the supabase local state and run the following command:
+
+```bash
+pnpm run supabase:web:typegen
+```
+
+This will regenerate the types according to the changes in the repository and your local changes.
+
+For the rest of the files, you need to resolve the conflicts manually.
