 # Getting Started with PyTC Client
 
-PyTC Client (PyTorch Connectomics Client) is a desktop application for biomedical image segmentation. It provides tools for managing files, visualizing data in Neuroglancer, training and running inference with deep learning models, proofreading synapse annotations, and detecting errors in image stacks.
+PyTC Client (PyTorch Connectomics Client) is a desktop application for biomedical image segmentation. It provides tools for managing files, visualizing data in Neuroglancer, training and running inference with deep learning models, monitoring experiments, and reviewing image masks.
 
 ## Launching the Application
 
-When you first open PyTC Client, a **Change Views** dialog appears. This lets you choose which workflow tabs to enable. The available workflows are:
+When you first open PyTC Client, the main workflows are available immediately in the top navigation bar:
 
 - **File Management** — Browse, upload, and organize files on the server
 - **Visualization** — View image and label data in Neuroglancer
 - **Model Training** — Configure and launch training jobs
 - **Model Inference** — Run inference with trained models
 - **Tensorboard** — Monitor training metrics in real time
-- **SynAnno** — Proofread synapse annotations
-- **Worm Error Handling** — Detect and classify errors in worm image stacks
-
-Check the workflows you want, then click **Launch Selected**. You can change your selection later by clicking **Change Views** in the top navigation bar.
+- **Mask Proofreading** — Review and edit mask layers in image stacks
 
 ## Application Layout
 
 The application has three main areas:
 
-1. **Top Navigation Bar** — Displays the PyTC logo, application title, and a row of tabs for each enabled workflow. Click a tab to switch between pages. The bar also includes a **Change Views** button and an **AI Chat** toggle button.

-# SynAnno Proofreading Page
-
-The SynAnno (Synapse Annotation) proofreading page lets you review and classify predicted synapse detections. It displays a Neuroglancer 3D viewer alongside a list of synapses and classification controls, enabling efficient annotation workflows.
-
-## Layout
-
-The proofreading page is divided into three panels:
-
-1. **Synapse List (left panel)** — A scrollable list of all synapses in the current project. Each entry shows:
-   - **Synapse ID** (e.g., "Synapse #1")
-   - **Position** coordinates (x, y, z)
-   - **Confidence** score (percentage)
-   - **Status icon** — A colored icon indicating the current classification:
-     - Green checkmark = Correct
-     - Red X = Incorrect
-     - Yellow question mark = Unsure
-     - No icon = Unreviewed
-   - A **progress bar** at the top showing how many synapses have been reviewed out of the total.
-
-2. **Neuroglancer Viewer (center panel)** — A 3D viewer displaying the image volume. When you select a synapse, the viewer centers on that synapse's location. A **Refresh** button appears in the top-right corner to reload the viewer. The current synapse ID is displayed next to the refresh button.
-
-3. **Proofreading Controls (right panel)** — Controls for classifying the selected synapse and editing metadata.
-
-## Reviewing Synapses
-
-1. Click on any synapse in the **Synapse List** to select it. The list highlights the selected synapse with a blue background and left border. The Neuroglancer viewer navigates to that synapse's 3D position.
-
-2. In the **Proofreading Controls** panel, you will see:
-   - **Synapse info** — The synapse ID, position, and confidence score.
-   - **Status Classification** buttons:
-     - **Correct (C)** — Green button. Mark the synapse as a true positive.
-     - **Incorrect (X)** — Red button. Mark the synapse as a false positive.
-     - **Unsure (U)** — Yellow button. Mark the synapse as uncertain.
-   - **Pre-synaptic Neuron ID** — A text input to enter or edit the pre-synaptic neuron ID number.
-   - **Post-synaptic Neuron ID** — A text input to enter or edit the post-synaptic neuron ID number.
-
-3. After setting the classification and optionally entering neuron IDs, save your work:
-   - Click **Save (S)** to save the current synapse's classification and neuron IDs.
-   - Click **Save & Next (→)** to save and automatically advance to the next synapse in the list.
-
-## Keyboard Shortcuts
-
-These shortcuts work when the proofreading page is active and you are not typing in an input field:
-
-| Shortcut        | Action                            |
-| --------------- | --------------------------------- |
-| C               | Mark current synapse as Correct   |
-| X               | Mark current synapse as Incorrect |
-| U               | Mark current synapse as Unsure    |
-| S               | Save current synapse              |
-| Arrow Right (→) | Move to the next synapse          |
-| Arrow Left (←)  | Move to the previous synapse      |
-
-## Workflow Tips
-
-- Use **Save & Next** (or press **S** then **→**) for rapid sequential review.
-- The progress bar at the top of the synapse list helps you track how many synapses you have reviewed.
-- You can click any synapse in the list at any time to jump to it — you do not have to review them in order.
-- Neuron ID fields are optional and can be filled in during a second pass.
