This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Install Opensidian as a system package on Ubuntu: https://dedupedai.com/use-cases/jpzk-opensidian/install-opensidian-deb-on-ubuntu/ - Check a release download against the signed checksums: https://dedupedai.com/use-cases/jpzk-opensidian/verify-release-download-before-install/ - Build Opensidian from source with a pinned Rust toolchain: https://dedupedai.com/use-cases/jpzk-opensidian/build-opensidian-from-source-with-rust/ - Open an existing Obsidian vault and add a community theme: https://dedupedai.com/use-cases/jpzk-opensidian/move-obsidian-vault-and-add-theme/ - Link research notes with wikilinks and attach PDFs and images: https://dedupedai.com/use-cases/jpzk-opensidian/link-research-notes-with-backlinks-and-files/ ## How to install Opensidian as a system package on Ubuntu with Opensidian Repo: [jpzk/opensidian](https://github.com/jpzk/opensidian) | Difficulty: Beginner | Time: 15 minutes | Basis: From the README Install the DEB package to get a menu entry, icon, and the notes app in one step. **Who it is for:** An Ubuntu or Debian user who wants a markdown notes app and does not want to build anything. **The problem:** They want a notes app that opens from the desktop menu without managing WebKit or Rust themselves. **The outcome:** Opensidian is installed as a system package and starts from the application menu. ### Steps 1. Download the DEB file from the Install section of the Opensidian README (opensidian-0.6.2-x86_64.deb). 2. Open a terminal in the folder where the file was saved. 3. Run `sudo apt install ./opensidian-0.6.2-x86_64.deb` 4. Open the application menu and launch Opensidian. 5. Open a vault folder with the Opensidian command, as described in the README features. ### Prompt to paste into your agent ```text In the jpzk/opensidian repo, follow the Install table to download the DEB package for version 0.6.2 into , then install it with apt. Report the exact apt output line that confirms installation. Verify that running `opensidian --version` or launching it from the menu opens a window. ``` ### Caveat The README says the app is under heavy development and the DEB was tested on Debian 13 and Ubuntu 26.04 LTS only.

Download the file you want, plus SHA256SUMS and SHA256SUMS.asc from the v0.6.2 release page, using `curl -LO https://github.com/jpzk/opensidian/releases/download/v0.6.2/SHA256SUMS` 2. Import the maintainer key with `gpg --keyserver hkps://keys.openpgp.org --recv-keys A6E69ED6BC4779F3281721484CC1AFDE15B64EA3` 3. Check the signature with `gpg --verify SHA256SUMS.asc SHA256SUMS` 4. Check the file hashes with `sha256sum -c --ignore-missing SHA256SUMS` 5. Install or run the file only if every checked line reports OK. ### Prompt to paste into your agent ```text In the jpzk/opensidian repo, download SHA256SUMS and SHA256SUMS.asc for v0.6.2 into , import the key listed in the README, and run gpg verify and sha256sum -c. Report the gpg verification result and each OK line. Verify that the gpg output shows a good signature from the expected key fingerprint before reporting success. ``` ### Caveat The check only proves the file matches what the maintainer published, so it depends on the key being the real maintainer key from the README.

Install the system dependencies for your distro from the Build from source section, for example `sudo apt install build-essential libssl-dev libwebkit2gtk-4.1-dev libgtk-3-dev libayatana-appindicator3-dev librsvg2-dev` on Ubuntu or Debian. (inferred, check the README) 2. Install Rust 1.98.0 if you do not have it, using `curl --proto '=https' -sSf https://sh.rustup.rs | sh -s -- --default-toolchain 1.98.0` 3. Load the Rust environment with `. "$HOME/.cargo/env"` 4. Clone the repo with `git clone https://github.com/jpzk/opensidian && cd opensidian/src-tauri` 5. Build the release binary with `cargo build --release --locked` ### Prompt to paste into your agent ```text Clone jpzk/opensidian into , go to src-tauri, and run cargo build --release --locked using Rust 1.98.0. Report the final cargo line and the path of the built binary. Verify that target/release/opensidian exists and is executable before reporting success. ``` ### Caveat The README reports a build of about 2.5 minutes on 4 cores with Rust 1.98.0, and older distro rustc versions may fail, so the pinned toolchain matters. Risk, remote script: The README's rustup step pipes a script from sh.rustup.rs straight into sh, so review that script or install Rust by another route if you prefer.

Open your vault folder in Opensidian with the Opensidian command, as shown in the README features. 2. Create the folder .obsidian/themes/ inside the vault, with one subfolder per theme named after the theme's name field. 3. Copy the theme's manifest.json and theme.css into that subfolder. 4. Open Settings, then Appearance, then Themes, and choose the theme. 5. If the theme is broken, check the greyed-out reason shown next to it; the app stays on AnuPpuccin. ### Prompt to paste into your agent ```text Given a vault at and a theme folder at containing manifest.json and theme.css, copy the theme into /.obsidian/themes//. Report the target folder path and the theme name from the manifest. Verify that the manifest name matches the folder name before reporting success. ``` ### Caveat The README says most Obsidian community themes work as they are, but not every theme is guaranteed to render correctly.

Open your research vault in Opensidian. 2. Write notes and connect them with [[wikilinks]] between related topics. 3. Open the backlinks panel and the graph view to review how notes connect. 4. Drag a PDF from your file manager onto a note; the original stays and `![[name]]` is inserted where you dropped it. 5. Drag a png, jpg, gif, or webp image onto a note; the image is moved into the vault and `![[name]]` is inserted. ### Prompt to paste into your agent ```text In an opensidian vault at , list the notes that contain [[wikilinks]] to , and report the names of notes that link back to it. Verify that each reported link target exists as a file in the vault before listing it. ``` ### Caveat The README says a PDF must really start with %PDF- to be accepted, and other file types are refused and left where they are.
