 ## Publishing
 
-TODO: Update after implementing automated publishing.
+1. Update version and create tags
+
+For each package in the following order: `shared`, `taco-auth`, `taco`, do the following:
+- Update the `version` value in corresponding `package.json`
+- Commit the change using the following commit message:
+```
+chore(release): release @nucypher/<package>:<new_version>
+```
+- Tag the commit
+```bash
+git tag <package>@<version>
+```
+
+2. Push the commits, and the tags
+```
+git push orgin <branch> && git push origin shared@<new_version> && git push origin taco-auth@<new_version> && git push taco@<new_version>
+```
+* NOTE: each `<new_version>` may be a different value
+
+3. Publish `@nucypher/shared`, `@nucypher/taco-auth` and `@nucypher/taco` packages to npm.
+
+Perform a dry run to observe the eventual outcome without actually publishing
+```bash
+pnpm publish -r --filter '!@nucypher/pre' --dry-run
+```
+
+If the outcome looks good then re-run the command without the `--dry-run` parameter
+```bash
+pnpm publish -r --filter '!@nucypher/pre'
+```
+
+View resulting published versions:
+- [@nucypher/shared](https://www.npmjs.com/package/@nucypher/shared?activeTab=versions)
+- [@nucypher/taco-auth](https://www.npmjs.com/package/@nucypher/taco-auth?activeTab=versions)
+- [@nucypher/taco](https://www.npmjs.com/package/@nucypher/taco?activeTab=versions)
+
+4. Tag latest release of `@nucypher/taco` for various domains where appropriate:
+```bash
+npm dist-tag add @nucypher/taco@<new_version> devnet
+npm dist-tag add @nucypher/taco@<new_version> testnet
+npm dist-tag add @nucypher/taco@<new_version> mainnet
+```
+
+where `<new_version>` is the latest version that was published.
