-## Adding to a New Project
+## Cloning a Project That Uses This Library
+
+The library is a submodule — it does not download automatically with a plain clone.
 
 ```bash
-# Add as submodule — lib/shared is the conventional mount point
+# Clone and initialise submodule in one step
-git submodule add https://github.com/AidanBrzezinski/KiCad_Library lib/shared
+git clone --recurse-submodules https://git.lokislair.com/aidanbrzezinski/YourProject
 
-# Commit the submodule reference
+# Or if you already cloned without it
-git add .gitmodules lib/shared
-git commit -m "lib: add shared KiCad library as submodule"
-git push
-```
-
-When cloning a project that uses this library:
-
-```bash
-# Clone with submodules in one step
-git clone --recurse-submodules https://github.com/AidanBrzezinski/YourProject
-
-# Or initialise submodules after a plain clone
 git submodule update --init --recursive
 ```
 
----
+To never think about this again, set this globally on your machine:
-
-## Setting Up KiCad Library Tables
-
-**This step is required every time you add this library to a new project.**
-
-KiCad locates symbol and footprint libraries through two plain-text table files:
-
-| File | Purpose |
-|---|---|
-| `sym-lib-table` | Registers all symbol libraries (.kicad_sym) |
-| `fp-lib-table` | Registers all footprint libraries (.pretty folders) |
-
-**These files must live in the project root** — the same folder as the `.kicad_pro` file.
-They cannot live inside the submodule. KiCad looks for them relative to the open project.
-
-### Step 1 — Copy the table files from the submodule into your project root
 
 ```bash
-# Run from your project root
+git config --global submodule.recurse true
-cp lib/shared/sym-lib-table ./sym-lib-table
-cp lib/shared/fp-lib-table  ./fp-lib-table
 ```
 
-### Step 2 — Commit them to your project repo
+After that, `git pull` and `git clone` always include submodule updates automatically.
-
-```bash
-git add sym-lib-table fp-lib-table
-git commit -m "lib: add KiCad library table files"
-git push
-```
-
-KiCad detects these files automatically the next time the project is opened.
-Anyone who clones the project repo gets correct library registrations immediately —
-no manual configuration required on their machine.
 
 > **If KiCad prompts about missing libraries on open:** the submodule was not
 > initialised. Run `git submodule update --init --recursive` and reopen the project.
 
-> **If you add libraries manually via KiCad's GUI:** KiCad will modify these files.
+---
-> Commit the updated versions so other machines stay in sync.
 
-### Why `${KIPRJMOD}` and not an absolute path
+## Adding This Library to a New Project
-
-All paths in these table files use `${KIPRJMOD}` as the root:
-
-```
-${KIPRJMOD}/lib/shared/symbols/0_ic_logic.kicad_sym
-```
-
-`${KIPRJMOD}` is a KiCad built-in variable that always resolves to the folder
-containing the `.kicad_pro` file, regardless of OS or where the repo is cloned.
-Never replace this with an absolute path — it will break on every other machine.
-
-### Keeping table files in sync with the library
-
-If the library adds a new category and updates its own `sym-lib-table` or `fp-lib-table`,
-re-copy them into your project root:
 
 ```bash
+# From your project root
+git submodule add https://git.lokislair.com/aidanbrzezinski/KiCad_Library lib/shared
+
+# Copy the library table files into the project root
 cp lib/shared/sym-lib-table ./sym-lib-table
 cp lib/shared/fp-lib-table  ./fp-lib-table
-git add sym-lib-table fp-lib-table
+
-git commit -m "lib: sync library table files from submodule"
+# Commit everything
+git add .gitmodules lib/shared sym-lib-table fp-lib-table
+git commit -m "lib: add shared KiCad library as submodule"
+git push
 ```
 
+KiCad reads `sym-lib-table` and `fp-lib-table` from the project root automatically.
+These files must live in the **project root** — not inside `lib/shared`.
+Always use `${KIPRJMOD}` in paths, never an absolute path.
+`${KIPRJMOD}` resolves to the project root on any machine regardless of OS or
+directory structure, keeping the repo portable.
+
 ---
 
-## Updating the Library From Within a Project
+## Best Practices
 
-The submodule is pinned to a specific commit. It **never updates automatically** —
+**Never modify the symbol drawing for standard parts.**
-this ensures a library change can never silently break an existing project.
+When copying from KiCad's global library, only change fields — never move pins,
+resize the body, or change pin length. This keeps visual consistency across
+every schematic that uses the library.
 
-### Check which library commit your project is pinned to
+**Always use the full MPN as the symbol name.**
+`SN74HC193DR` not `SN74HC193` or `74HC193`. The package suffix matters —
+it determines the footprint and is what gets ordered from Digikey.
 
-```bash
+**One component per commit where possible.**
-git submodule status
+Makes git history readable and makes it easy to revert a bad footprint
-# +a3f8c2d lib/shared (heads/main)
+without affecting anything else.
-#  ^ the hash is the exact commit your project uses
+
-```
+**Push library commit before updating the project pointer.**
+If you update the pointer before pushing, other machines get a broken
+submodule reference that cannot be resolved.
+
+**Verify custom footprints against the physical part before committing.**
+Draw from the datasheet first. When parts arrive, check with calipers.
+A pad spacing error costs a full board respin.
+
+**Re-copy table files when library categories are added.**
+If `sym-lib-table` or `fp-lib-table` is updated in the library (new category added),
+re-copy them into your project root and commit. See [Updating the Library](#updating-the-library-inside-a-project).
+
+**Never register this library globally in KiCad.**
+Global registration uses absolute paths that break on other machines.
+Always use project-level table files with `${KIPRJMOD}`.
+

-## Best Practices
+## Naming Conventions
 
-**One component per commit where possible.**
+### Symbol names
-Makes git history readable and makes it easy to revert a bad footprint
+Always use the full MPN including package suffix:
-without affecting anything else.
+```
+SN74HC193DR      ✓   includes package suffix (SOIC-16)
+SN74HC193        ✗   ambiguous — which package?
+74HC193          ✗   missing manufacturer prefix
+```
 
-**Never modify the symbol drawing for standard parts.**
+### Footprint file names
-When copying from KiCad's global library, only change fields — never move pins,
+```
-resize the body, or change pin length. This keeps visual consistency across
+# Standard packages — KiCad convention
-the schematic.
+SOIC-16_3.9x9.9mm_P1.27mm.kicad_mod
 
-**Always verify custom footprints against physical parts.**
+# Custom parts — MPN + package
-Draw from the datasheet first. When parts arrive, check with calipers before
+HV5622PG_DIP44.kicad_mod
-sending PCB to fab. A pad spacing error costs a full board respin.
 
-**Keep the library repo and project pointer in sync.**
+# Custom parts with no single MPN — function + mounting type
-Push library commits before updating the project's submodule pointer.
+IN14_NixieTube_THT.kicad_mod
-If you forget, other developers get a broken submodule reference.
+EC11_Encoder_THT.kicad_mod
+```
 
-**Update the sym-lib-table and fp-lib-table in the library when adding categories.**
+### 3D model file names
-Then re-copy them into any project that uses this library (see sync instructions above).
+Match the footprint name exactly:
-This way all projects get the new category without manual GUI registration.
+```
+HV5622PG_DIP44.step
+IN14_NixieTube_THT.step
+```
 
-**Never register libraries globally in KiCad for project-shared libraries.**
+### Datasheet URLs
-Global registration uses absolute paths that break on other machines. Always
+Always link directly to the manufacturer PDF, not a product page:
-use `${KIPRJMOD}` via project-level table files as described above.
+```
+# Texas Instruments
+https://www.ti.com/lit/ds/symlink/sn74hc193.pdf
 
-**Add the Datasheets/ folder .gitignore if datasheet size becomes a concern.**
+# ON Semiconductor
-For now all PDFs are committed directly. If the repo grows too large,
+https://www.onsemi.com/pdf/datasheet/mc74hc193a-d.pdf
-switch to storing only datasheet URLs in the symbol Datasheet field instead.
+
+# Microchip
