+# GIT CHEATSHEET
+## By Sharvil (20240927)
+Perform these steps on creating a new project.
+
+_**ASSUMPTION:** You are already in your project directory in the command line terminal._
+
+---
+
+### STEP 0.
+#### Initialize Git in your new project:
+Do this when creating a new project directory.
+Do this **ONLY ONCE**.
+```commandline
+git init
+```
+
+### STEP 1. 
+#### Create a `.gitignore` file:
+Add files/directories in it which you don't want to sync to git.
+Update this as frequently as your project needs you to. Start with this:
+```
+/.venv/
+/.idea/
+**/__pycache__/
+*.pem
+```
+
+### STEP 2. 
+#### Create a repository on Gitea (web UI):
+Do this **ONLY ONCE**.
+Open the following URL: https://wtt.ditscentre.in/ and sign in.
+- Ensure that the owner is `ditscentre` (img 0).
+- Give your repository a name. Preferably keep it the same as the project name that you made locally (img 0).
+- Type in a brief description of your project (img 0).
+
+![img 0](https://nexcom.ditscentre.in/utils/files/small/download/66f66a54196705ee2f25d28e)
+
+- Ensure that the default branch is `master` (img 1).
+- Create the repository (img 1).
+
+![img 1](https://nexcom.ditscentre.in/utils/files/small/download/66f66a54196705ee2f25d28f)
+
+### STEP 3. 
+#### Add files and directories to the staging area:
+The following command adds everything to the staging area.
+The '.' is important, it refers to the current directory.
+```commandline
+git add .
+```
+
+### STEP 4. 
+#### Commit the changes to local git:
+This step commits all the added (staged) changes to the local git instance with the provided comment.
+```commandline
+git commit -m "you comment here..."
+```
+
+### STEP 5. 
+#### We push the local commits to the repository:
+The format of the command is:
+```
+git push -u <repo_url> <branch_name>
+```
+
+---
+
+## For Python Devs: How to add a common subtree (like `utils_v2`)
+
+The format of the command is:
+```
+git subtree add --prefix=<local_dir> <subtree_repo_url> <branch_name> --squash
+```
+Before you start: ensure that you have committed all pending changes. Then run the following command **ONLY ONCE**:
+```commandline
+git subtree add --prefix=utils_v2 https://wtt.ditscentre.in/ditscentre/utils_v2.git master --squash
+```
+This will create a new directory named `utils_v2` in your project.
+**Do NOT change the files in it.** Just import and use them in your scripts.
+When you need to get the latest updates to these files, you must run a modification of the previous command:
+```commandline
+git subtree pull --prefix=utils_v2 https://wtt.ditscentre.in/ditscentre/utils_v2.git master --squash
+```
