+# TALA
+
+TALA is Terrastruct's proprietary diagram layout engine, made for
+[D2](https://github.com/terrastruct/d2). TALA is closed-source (for now). This repository
+is primarily for installation instructions. You can also use this repository to report
+issues, ask questions, and request features.
+
+To learn more about TALA, please visit
+[https://terrastruct.com/tala](https://terrastruct.com/tala).
+
+To compare TALA with other layout engines, please visit
+[https://text-to-diagram](https://text-to-diagram).
+
+## Installation
+
+TALA is freely installable and locally runnable for evaluation. You'll need an API token
+from your Terrastruct account to run it out of evaluation mode.
+
+### Prerequisites
+
+You should install D2 first. TALA is installed as a standalone binary in your path which
+D2's plugin system calls out to.
+
+### Install
+
+#### MacOS
+
+```sh
+brew install --cask d2talaplugin
+```
+
+#### Others
+
+We are working on adding to package managers and a universal install script that'll detect
+OS's. For now, you can find binaries in the
+[Releases](https://github.com/terarstruct/TALA/releases) page for Linux, Windows, MacOS, for
+both AMD and ARM (64-bit for all). Download the appropriate one for your OS to a directory
+in your path.
+
+### Post-install
+
+Check that it was installed properly:
+
+```sh
+d2 layout tala
+```
+
+It should print out information about TALA. If not, please see troubleshooting steps.
+
+### Use TALA
+
+You are now ready to use TALA to layout your diagrams! Specify that D2 should use TALA by
+setting the environment variable `D2_LAYOUT`.
+
+```sh
+D2_LAYOUT=tala d2 in.d2 out.svg
+```
+
+### Add API token (optional)
+
+You may skip this step if you are just evaluating.
+
+If you have an API token from your Terrastruct account, copy and paste it into your
+environment variables. E.g.
+
+```bash
+export TSTRUCT_TOKEN = "tstruct_..."
+```
+
+### Troubleshooting
+
+#### TALA not found
+
+```sh
+which d2talaplugin
+```
+
+If this does not return a directory, then `d2talaplugin` is not in your path.
+
+```sh
+echo $PATH
+```
+
+Please move the downloaded binary to one of those locations.
+
+#### License warning prints even with API token
+
+In the same terminal that you're running `d2` on, run
+
+```sh
+echo $TSTRUCT_TOKEN
+```
+
+If it is not found, then your environment variable has not been set in your shell. Make
+sure you add it to the appropriate shell config file and `source` it in the running
+terminal.
